What gives a motorcycle more torque?
Take the two chain sprockets on our motorcycle for example. To increase the torque at the rear wheel, the rear sprocket is larger than the front sprocket. In other words, the radius of the rear sprocket is bigger. Bigger radius with same force means higher torque.
What are the torque producing engine?
Torque is a rotating force produced by an engine’s crankshaft. The more torque an engine produces, the greater its ability to perform work. The measurement is the same as work, but slightly different. Since torque is a vector (acting in a certain direction), it’s quantified by the units pound-feet and newton-meters.
Why engine torque is in a curve?
They are related and proportional to each other by speed. The ‘torque-band’ in an engine curve represents its pulling ability which determines a vehicle’s ‘driveability’ & ‘acceleration’. Torque is most needed while moving a vehicle from the stand-still and/or climbing a slope.
Which is more important torque or horsepower?
Well, if you just want to go fast and hit 140 mph, then horsepower would be more effective for you. However, if you want a strong car that can pull boulders and take off quickly, a high torque might be more important to you. In short, torque makes your vehicle quick. Horsepower makes it fast.
How do you calculate maximum torque of an engine?
Calculate torque (T) using the formula T = 5,252 x horsepower/rpm. The results are measured in pound-feet. For example, if you have a 40-horsepower motor designed to operate at a peak of 1,200 rpm, the formula would be T = (5,252 x 40)/1200 = 175.07 lb.
What is the rpm for maximum torque of today’s engines?
The power band of an internal combustion gasoline automobile engine typically starts at midrange engine speeds (around 4,000 RPM) where maximum torque is produced, and ends close to the redline after reaching maximum power between 5,000 and 6,500 RPM.
How does torque help a bike?
What is Torque in Bikes? In other words, it’s the amount of force or twisting force that is available at the wheels to propel the bike further. Such bikes that consist of lower torque can help in moving the bike at a faster speed while having higher torque can enable the bike to move greater loads.
Why do motorcycles have power and torque numbers?
Power tells how fast you can work, and a motorcycle works when it accelerates, when it climbs a hill, and even when it rides at a constant speed: the air resistance and all friction (in the motorcycle itself as well) has to be overcome. So, power tells you how fast a motorcycle can do all those things. So why show the torque?
How much torque does a Harley Davidson Electra have?
A Harley Davidson Electra Glide has about 13 KGM (92 lb ft) torque , about twice as the common 600 cc hyper sport motorcycle has, yet the later will be much faster. There is more emphasis on the RPM , which the peak torque is produced. And I’ll give a classic example – the two stroke 125 cc Cagiva Mito.
How do you calculate the power of a motorcycle?
Power is expressed in kilowatt (Kw) or in Horsepower (Hp). When you know the torque of your motorcycle with a given rpm, you can deduce the power, by multiplying the torque with the number of revolutions per minute (and of course with a constant factor to adjust the different dimensions like rpm, Hp and Nm). Torque and power curve
What is an example of a low rpm motorcycle?
Another example is the Yamaha VMax: lots of torque, with very low rpm’s. Motorcycles with this strategy are often motorcycles with a high capacity (many cubic inches): then the torque at low rpm’s may be so high that the maximum power is still reasonable, even when power is not what the engine is optimized for.
