Things Which You Should Avoid When You Start Your Motorcycle Tomorrow

If you’ve never travelled by motorcycle, we strongly encourage you to give it a try and see what you’ve been missing all these years. Riding a motorcycle is one of the most liberating experiences you can have in life. Your safety is sacred, thus you must take all reasonable precautions and efforts to prevent getting into an accident in the first place or suffering as a result of someone else’s negligence while driving. If you are unfortunate enough to lose your balance and have an accident, you may keep yourself safe and shield your body from physical harm by always wearing motorcycle safety gear.

There are a few mistakes you should never make in addition to being safe with branded motorcycle riding gear like a helmet and gloves. The seven frequent errors that frequently result in accidents have been gathered. Examine them to avoid them at all costs.

  1. Don’t tie shoelaces in loops: Have you ever wondered why riding boots for motorcycles lack lasers? It’s because the laces could obstruct you from applying the brakes or changing gears, or they could tangle in the brake lever and cause an accident. Even if you have to wear a pair of lace-up everyday boots, take care to avoid tying the laces in loops that could get caught in the foot pegs or on the gear lever. For further security, it’s a good idea to tie the loops under your heel and keep it tucked within the boot.
  2. Don’t watch the speedometer, watch the road: Your attention should always be on the road when you are riding a motorcycle. Many people make the error of keeping an eye on the speedometer when travelling at high speeds just for their own satisfaction. Because you don’t have much time to correct errors, if any when you’re moving quickly, it’s one of the most frequent blunders that you should avoid. Even if you must check your speed to comply with posted speed restrictions, do so swiftly and return to the road as soon as you can.
  3. Watch the tires of the vehicle in front of you( Don’t trust brake lights blindly): It’s possible for someone to abruptly decide to change lanes without adequately notifying you while you’re sharing the road with several other vehicles travelling in separate lanes. By carefully observing the road, you can prevent the accidents that are frequently caused by this. You should pay attention to the wheels of the vehicle, which will turn slightly before making the lane change, rather than the brake or signal lights of the car in front of you. This will allow you enough time to take evasive action and protect yourself.
  4. Don’t change speed in the middle of the corner: Changing the motorcycle’s speed in the middle of a corner is another typical error that motorcyclists need to avoid making. Determine whether the bend is suitable for the pace you are travelling at. If you believe you are travelling at a speed that the motorcycle cannot handle, slow down before entering the corner and adopt a lean angle that will allow you to control the motorcycle. Avoid changing your line once you’re in the turn since there is a very significant probability that you will lose your balance and crash the bike.
  5. Change gear before an overtake, not during an overtake: In the same way that you must keep the motorcycle moving at a constant pace while rounding a corner, you must do the same when passing another vehicle. A sudden gear shift in the middle of an overtake will cause the RPMs to drop, which will slow you down and could result in a car-ramming you from behind! Reduce the gear one step, follow the torque curve, gather speed, and then pass the moving object. Change the gear after your manoeuvre is finished.
  6. Do not use high-beam in traffic: A driver in the oncoming lane may become completely disoriented and lose their bearings if a bright light shines straight into their eyes. If this happens, the vehicle may jump the divider line and strike you tragically. The vehicles directly in front of you will find comfort in a brilliant beam of light since it will reflect in their rear-view mirror and fall squarely on the rise, potentially causing them to brake suddenly and put you in danger of hitting them from behind. Since you are riding a motorcycle, you are more likely to suffer catastrophic injuries if that occurs. Because of this, it is your obligation to be safe. Never use your high lights in bumper-to-bumper traffic or even in lane segments that are closely spaced apart.
  7. Avoid riding behind the centre of a car: Cars and other four-wheeled vehicles arrange their wheels so that the middle of the vehicle travels over potholes while the wheels entirely avoid them. You run a good possibility of unexpectedly crashing into a pothole if you are riding exactly behind the centre of a four-wheeler. Always leave adequate space between you and the car in front of you so that you have time to negotiate such unexpected road hazards, but if you must follow a car closely due to unforeseen circumstances, make sure that you are riding behind the wheels rather than the centre of the car.

Why Yamaha R15 are the best ?-Know The Advantages!!!!

The Yamaha YZF-R15 has undergone a significant improvement in the 4.0 version, making it more desirable than ever. Here are five reasons to buy the new Yamaha YZF-R15 V4.0, which includes changes to the motorcycle’s design and upgraded functions.

Styling

The look of the brand-new Yamaha YZF-R15 V4.0 is one of the main selling points. One of the most attractive motorcycles in the sub-200cc category in the Indian market, the YZF-most R15’s recent iteration takes design cues from the current YZF-R7. Full fairings, an M-air duct up front, a single-pod headlight, dual LED DRLs, a bulky fuel tank, a step-up seat, and a side-slung exhaust are all features of the design. Five colour options are offered for the new YZF-R15 V4.0: Metallic Red, Dark Knight, Racing Blue, R15M, and Monster Energy MotoGP. Depending on the colour option chosen, the prices change.

Premium Features

An LED headlight, LED DRL, LED taillight, and a Bluetooth-enabled fully-digital instrument cluster are all standard features across all motorbike models. Access to services like call alerts, SMS and email notifications, and phone battery level is made possible by Bluetooth communication. The smartphone app displays information on the amount of fuel used, maintenance suggestions, where the vehicle was last parked, malfunction notifications, the rpm dashboard, and ratings. Dual-channel ABS, traction control, and side-stand engine cut-off are all examples of standard electronic rider aids. A quick-shifter is also included as standard on the Racing Blue and R15M models, whereas the function is an optional extra on other models.

Hardware Upgrade

Along with updated features and redesigned aesthetics, the Yamaha YZF-R15 V4.0 also receives updated hardware. As opposed to conventional units on the previous motorcycle, the suspension configuration now uses upside-down telescopic front forks, putting it on par with the international-spec model and with competitors like the KTM RC125 and the RC200. The rear’s mono-shock with preload adjustment is still used for shock absorption. A 282mm single disc in the front and a 220mm rotor at the back conduct the anchoring functions, and the setup provides impressive feedback.

Tried and tested 155cc Engine

The 155cc, single-cylinder, liquid-cooled engine with the Variable Valve Actuation technology is still present in the motorcycle. The motor, which is connected to a six-speed gearbox, produces 14.2Nm of maximum torque at 7,500 rpm and 18.1bhp at 10,000 rpm. The assist and slipper clutch mechanism is still used by the gearbox. Above 7,400 rpm, the variable valve actuation system engages to give powerful performance across the rev range. The motorcycle is reasonably speedy in the lower RPM range, but it starts to rev up at about 4,500 rpm.

Fun to ride

Because of its superb handling, the Yamaha YZF-R15 has always been a fantastic motorbike to ride. The delta box frame and the sporty suspension arrangement give the motorcycle a nimble and responsive feeling. However, comfort suffers as a result of this. Using the assist and slip feature, the clutch feels remarkably light.

Verdict

The Yamaha YZF-R15 V4.0 is a much-improved version of the previous model, and the motorcycle is now more enticing than ever. The newly revised style is immediately appealing, and the feature list raises the attractiveness level even more. The YZF-R15 V4.0 continues to be one of the most entertaining motorcycles to ride in its class thanks to its fast, 155cc engine. The high cost of all the updates, however, may influence some purchasers’ purchasing choices in the Indian market. Additionally, the aggressive rider triangle and the sporty suspension tuning might not be suitable for all purchasers, which might influence their purchase decisions.

Want to increase your bike’s mileage? Then don’t do these things!!!

Mileage is the working capacity and efficiency of a vehicle engine after burning a certain amount of petrol, diesel or gas as fuel. Everyone wants more mileage on their scooters, motorcycles, motorcycles, etc. Below are some of the most common reasons for low-mileage motorcycles.

A motorcycle’s fuel economy and mileage are is one of the most important parameters for a motorcycle driver to measure a motorcycle’s performance. With fuel prices rising, it is always important to understand the factors that reduce fuel efficiency and motorcycle mileage.

Reasons why motorcycle mileage can get low

1. Low tire pressure

This is the main reason why all types of two-wheelers have low mileage. Low tire pressure puts extra strain on the engine and reduces its ability to work.

2. Dry and dirty chain

Another cause is a dirty motorcycle rear wheel chain attached to the engine. A dirty and dry chain increases friction and reduces the rotational motion of the motor. As a result, the motorcycle has less mileage.

3. Hit the brakes

If the motorcycle’s brakes are locked, it will try to stop the engine’s rotational speed. The engine then works under the strong pressure generated by the braking system and Disc brakes and drum brakes are activated. This can cause the motor to overheat quickly.

4. Not change the oil for a long time

Long intervals in changing engine oils are another reason for lower mileage. The oil usually becomes dirty and dark in 3-4 months. This happens due to the normal operation of the engine.

5. Sticky with Dirty Air Filters

If the air filter is dirty, the mileage of the motorcycle will also be shortened. The air filter acts as a cooling device for the engine. When the engine heats up or overheats, its performance is reduced. 

6. Use of inferior fuel

Gasoline, petrol and diesel counterfeits are also the reason for low mileage. Hit the power of the engine directly. Cheap quality oil does not create strong pressure against the piston when the engine burns fuel in the combustion chamber.

7. Improper driving style

This means overloading the motorcycle, shifting gears too often, raising and lowering ramps, etc. Riding the bike this way means less mileage.

8. Bad road conditions

Poor road quality is also a reason for the low mileage. Bad roads force the driver to shift gears a lot. This reduces the working efficiency of the engine and also increases fuel consumption.

Charvi Motors makes sure to provide you and your bike the care that it needs making sure that your bike gets that perfect mileage.

5 Quick Facts About The Yamaha FZ 16 Motorcycle

The Yamaha FZ16 edition was launched back in 2010 on the primary generation of FZ. The motorbike carries a Blue and White livery whereas its pure White alloy wheels were the main attraction for each purchaser. it had been power-driven by identical 149 cc, single-cylinder FI engine manufacturing fourteen BHP and fourteen Nm of force. The engine comes mated to a 5-speed case and carries 267 mm of hydraulic brake for economical braking. The motorbike weighs 135kgs and claims a high speed of 132 kmph.

  1. The FZ-16 could be a looker and it instantly attracts attention. It’s out of the question to lose focus once you’re watching the new Yamaha – it’s each sonsy and crowd-pleasing. The Indian FZ borrows style cues from its stunning-looking massive brother, the FZ-1, and is equally dazzling to appear at. Negligible body facing is the rule on the FZ-16, with its engine and cycle elements chivalrously noticeable as necessary components of the bike’s general vogue.
  2. The new bike uses beautiful slim-spoke alloy rims in black and also the same colour scheme for its engine, swingarm and silencer. immense section tyres augment its charm, whereas a good, cone-shaped front light source with a pointy beam and tiny town light-weight stares forward from below the FZ’s diminutive liquid show (LCD) instrument bay. The instruments – as well as a rev counter, meter and indicator – provide bushed a sporty-looking digital arrangement.
  3. The new FZ-16 deploys a city-friendly, broad and to some extent, low-set bar, and uses grips with a good feel, marvellous levers, sensible mirrors and enough switchgear. A helpful engine-kill switch is a component of the package, as could be a handlebar-mounted choke lever on the left. There’s a colossal and splendidly carved  model rosin fuel tank as unremarkably found on superbikes, a brushed end alloy fuel filler that sadly, lacks a pivot and comfy knee recesses that fully tuck in a rider’s thighs. The tank is split by a daring secondary colour stripe down its centre, whereas the important 12-litre fuel-storage bay sits placed just under, by design nearer to the bike’s centre of gravity. The FZ-16 comes with a trendy engine cowl, made with vents to direct and scoop airflow straight to the engine and electrical device.
  4. Other spectacular details comprise alloy footrests for each rider associate degreed pillion; an uncovered O-ring sealed drive chain, a nattily dead rip grab-bar and an original rear tyre human. Look closely and you’ll see that the new Yamaha uses a compact sheared silencer that routes itself midship, below the bike’s swingarm and frame, within the section of its rear tyre human. The FZ-16’s flanks and tail square measure elegant, whereas its good tail light-weight is housed at intervals in the rear splash guard.
  5. The new Yamaha uses an all-new, four-stroke, single-cylinder and CV FI engine that displaces 149 cc. The cool powerhouse uses big-size fins on its cylinder, furthermore as cooling fins within the lower sump space of the facility plant.

Effect Of Old Engine Oil/Grease as Lubricant for Bike’s Chain & Sprocket

The chain of a motorbike desires constant lubrication to function at its highest potency. Since it’s the element that directly transfers the ability from the engine to the wheel, it perpetually stays in motion. Hence, it becomes imperative to form the operation resistance to cut back wear and tear.

Regular maintenance is needed to make sure that a chain continually runs smoothly, doesn’t rust and continues to function on the vehicle for an extended time. In addition to cleaning the chain, regular lubrication and oiling also are needed.

Instead of using used engine oil or grease, one ought to use the dedicated material to place it within the chain. The engine oil or grease left behind dirt and rubble on the sprocket. It gets accumulated over time and will have an effect on the performance of the chain. Since that impacts the ability to deliver, the performance of the bike is influenced.

To tackle this, one may use chain lube or gear oil. These oils are not very expensive and can be applied even at home. Additionally to the present, one should not use the regular brush to scrub the chain instead use the brush designed for it. This helps during a thorough cleansing of the chain beside the sprocket system that is usually hidden behind. Of these measures make sure that correct lubrication of the chain and sprocket is used.

How often you ought to lubricate the drive chain varies from person to person. Counting on the number of kilometers driven, climatic conditions, paved surface conditions, and quality of the chain as per handling and frequency of movement, this can be sooner or later.

The variety of lubricants and care products for vehicle chains is nearly unmanageable. The varied remedies all have their distinct benefits and drawbacks.

Dirt, mud and sand will then stick and therefore the chain becomes a lot stiffer over time. Motor oil doesn’t run smoothly enough and might barely penetrate into all the cracks within the chain so as to lubricate it.

If there’s an excessive amount of oil or material on the surface of the chain, it’ll solely attract a spare quantity of sand, dirt, mud and wet. These fine “foreign bodies” act like sandpaper when the bike will be used and unnecessarily sand the chain, pinion and sprockets. Use chain cleaner spray to get rid of excess material. So plenty of chain oil doesn’t help a lot, so it’s necessary to use smart Quality Chain material for a sleek ride. Due to less knowledge, many people find themselves doing the temporary resolution thinking that the right resolution may be very expensive. However, solutions like using the correct material and oil rather than using engine oil or grease for the chain and sprockets don’t seem to be valuable in any respect.

FI Engine: Yamaha’s New Leading Technology Benefits-At Charvi Motors, Mysore

Decades ago when Yamaha introduced its first-ever FZ FI in the market the scene was a whole lot different. And, the market dynamics we have today are primarily set by Yamaha.

Yamaha was firm and persistent in defying the culture of carburetors because the future Yamaha envisioned from its very first days was to provide low emission and high performance. Another reason for Yamaha to persistently promote the benefits of the FI engine was its concern for the environment over cost-saving, and its responsibilities as a leading distributor to invest for a better future.

Since the invention of the internal combustion engine, automobile engineers have strived to find effective ways to deliver air and fuel to the combustion engine. The device which controls the ratio of the air-fuel mixture entering the engine is known as a carburetor, a fuel injection system also does the same.

In simple terms, a carburetor helps the air-fuel mixture to enter the combustion chamber. All this is done through mechanical parts. The fuel injection system also helps the combustion chamber to get an air-fuel mixture, but with the aid of electronics and sensors, and not through mechanical parts.

The fuel injection system comprises a complex set of electronic components and sensors. The system depends on a fuel pump to control the flow of fuel to the combustion chamber. This fuel pump is located inside the fuel tank of the bike. The supply of fuel to the combustion chamber is enabled through an Electronic Control Unit (ECU). This electric brain constantly monitors and makes complex calculations to deliver the best possible air-fuel mixture.

The complex calculations include parameters such as throttle position, engine speed, engine temperature and load, among others. The nozzle of the fuel injection system goes right into the chamber of the cylinder. Hence, the ECU directs the injectors to control the amount of fuel to enable the most efficient mode of combustion.

Fuel-injected engines are efficient when we talk ‘work’. By efficient, I mean the overall engine performance increases. A pump is actually located in the system that makes sure that the fuel efficiently mixes with air and is supplied to the combustion chamber to produce efficient power.

The pump regulates and utilizes the amount of fuel that is subjected to the combustion chamber. The accelerator acts as a command for the pump to start pouring the required amount of fuel and air to burn, making the engine generate more power and it results in enhanced throttle response.

Here are the advantages of fuel injection system on bikes:

  • Accurate air-fuel mixture and atomisation.
  • Cleaner and more efficient combustion.
  • Sharper and quicker throttle response.
  • Better fuel efficiency or mileage.
  • Compared to carburetors, FI systems are maintenance-free and less prone to damage.
  • Can easily be tuned through ECU mapping.

10 Tips to Improve Your Vehicle Mileage

Simple ways to get better fuel efficiency without you having to be adept at the mechanics that power your two wheeler, so that you can drive past the fuel pump more often than you stop there.

  1. KEEP THE PRESSURE ON- Driving with optimal tyre pressure makes a huge difference to your two wheeler’s fuel efficiency. Reduced tyre pressure means increased contact area between the tyre and the road. As a result friction between the rubber of the tyre and the road increases, resulting in higher fuel consumption. Over-inflated tyres will mean a lower consumption, but at the cost of grip and ability to disperse water on the road. Make sure the tyres are inflated at the manufacturer recommended levels and you’ll be fine. And don’t forget to check them once a week, always in the morning.
  2. SMOOTH OPERATOR- Be as smooth as possible with the two wheeler’s controls. Treat the accelerator and the brake pedals with respect. Rough speedy acceleration and sudden brakes might be more fun on the road but harms your vehicle’s fuel efficiency.
  3. CONSOLIDATE TRIPS- Two short trips will inevitably consume more fuel than one that is slightly longer. This is because your two wheeler consumes extra fuel each time you crank the engine. Combine as many trips as possible to keep fuel efficiency high. As a bonus, you’ll also be saving on traveling time.
  4. KEEP IT SHUT- A two wheeler’s fuel efficiency has a lot to do with how it parts air on the move. In other words, aerodynamics. High speeds can impact fuel efficiency and result in the tank draining out quicker due to increased drag.
  5. ALL GEARED UP- Shift to the highest possible gear without the engine knocking. A two wheeler consumes more fuel in lower gears when accelerating. If the engine’s not pulling, shift down instead of pressing the throttle. Shifting up at 2,000 rpm (1,500 rpm for diesel) gives the best mix of speed and economy. On an automatic with manual shift, short shift to save fuel.
  6. Avoid Over-revving- Over-revving can affect mileage negatively. Hard acceleration consumes more fuel. Hence, if you are willing to improve two wheeler mileage and save fuel, try to accelerate slowly and gradually.
  7. Use Gears Correctly- Changing gears correctly is essential to ensure high mileage. This applies to both manual and automatic transmission two wheelers. Use gears at the correct speed, which will help save fuel.
  8. Check Wheel Alignment- Misaligned two wheelers can adversely affect two wheeler mileage and fuel economy. Incorrect alignment can reduce fuel efficiency by up to 10%. Also, it can affect tyres as it would wear prematurely. Symptoms like a vibration in the steering wheel can result in uneven tyres, further leading to reduced two wheeler mileage. Hence, look closely at your tyres or visit any garage to ensure the tyres are properly balanced and aligned.
  9. Leave the Air-Con Turned Off- Unless it is a very high temperature outside, do not turn on the two wheeler aircon unnecessarily. Excessive usage can put a lot of strain on the engine and consume more fuel (especially at low speed). This is applicable for heated windscreens, demisters, etc.
  10. Maintain an Optimal Speed Limit- The list of tips to improve the mileage of a two wheeler includes maintaining an optimal speed limit as specified in the vehicle manual. As per research, driving at 80 mph uses up to 25% more fuel than 70 mph.

Short Discussion Grade for Motorcycle Engine Oils

Engine Oils are the most essential commodity in the running of your vehicles after fuel. It is this lube that keeps your engine running smoothly. But there are some specifics that every person using engine oil should know about. After all the marketing jargon that is thrown out to you about the oil’s performance and its capabilities, it all comes down to the basic technical specifications which we are going to explain to you here. We are not going to talk about the types of engine oils (that is a completely different part of the discussion), but we are going to check out the engine oil grades and what they mean.

If you check out any of the engine oils in the shops or online, you will be able to see one thing in pretty bold letters among everything else and that is a ‘W’ rating. You will be able to see numbers like 10W30, 20W50, 0W30, etc. which refer to Multigrade. These are the actual numbers that you have to consider while buying your engine oil because all the manufacturers recommend a certain grade of engine oil and these numbers are the actual grading system.

In the grading system of engine oils, (let’s consider 10W40 for example) the letter “W” stands for Winter and the number preceding the W is the low temperature count. That is the value which denotes the “low temperature performance of the engine oil”. For the engine oil to perform, it has to hold on to a certain viscosity level for optimum performance and so when the temperature fluctuates, the engine oil viscosity tends to get affected.

The low temperature rating starts from 0Wxx which is suitable for very cold climatic conditions with sub-zero temperatures. Here the 0Wxx oil holds its working viscosity even at such low temperatures. Though using this oil in hotter areas will not cause any problems to the engine but practically it is quite useless to use this oil as the real benefit of the oil will not be evident.

Coming to the hotter areas, the number following the W, (in our example is 40) is the number which determines the suitability of the oil performance in hotter temperatures. This also depends on a number of factors like engine revving, atmospheric temperature and engine cooling system. In the engine the temperature can reach over 100 degrees Celsius, and engine oils tend to lose their viscosity and get thinner if the temperatures go beyond their specified rating. This is the reason why most of the manufacturers recommend a certain grade of oil for a smooth running of the engine depending on the engine performance.

So if you have a high revving engine that heats up quite a lot, then a low rating of high temperature gradient will make the oil thinner and hence cause engine damage due to improper protection and high friction. Hence for that reason higher grade oil is more beneficial so that the oil holds its viscosity even at higher temperatures and provides the best engine performance.

So to sum everything up, the engine oil grading system has a low temperature and high temperature rating provided to choose the oil from as explained above. Though it is always better to stick to the engine oil recommended by your manufacturer, but if you are willing to change to some other brand of engine oil, always make sure to get the recommended grade of oil and only experiment when you are sure about your usage. For example; if you reside in a very hot climatic condition you can always use engine oil with higher temperature rating, like if you are using 10W40 oil you can go for 10W50 oil grade for better results.
