Why would a more efficient engine give a motorcycle a higher top speed?

At lower speeds traction is important and at higher speeds aerodynamic forces become significant. Again, the higher the power to weight ratio is the higher speed can be achieved in first gear (in general).

Are motorcycles faster than cars in corners?

Corner speed So over a course with a series of corners, a car can be faster than a motorcycle. “Also on tight roads, a bike is a smaller percentage of the road so it can manoeuvre through the same sequence of bends faster as the bike doesn’t need to do as tight a corner radius so the difference is reduced.”

Why do Harleys have such low horsepower?

Since Harley motors don’t generate a lot of RPM, their horsepower figures are low. In comparison, a Yamaha FZ1 engine displaces 1000cc’s, actually much less than the big V-Twin, but has over 100hp at 9k RPM. It stomps the Harley in roll on acceleration and top end speed.

How are motorcycle engines so powerful?

Motorcycle engines have very short strokes, which characterizes with: It allows higher RPM (because piston has shorter distance to pass, which means shorter cycle time, which means higher number of RPMs) Higher maximum power per same displacement (but torque is not higher) Higher fuel consumption.

What happens when you get a flat on a motorcycle?

Roll off the throttle smoothly, and try and stay off the brakes entirely as the bike slows down through engine braking. Apply both brakes gently once the bike has slowed significantly, and stay centered and balanced over the bike’s chassis. Slowly, gradually, bring your bike to a safe stop.

Are Harleys underpowered?

Cruisers, like Harley Davidson bikes, are slower than sports bikes because they have push-rod valve trains and are air-cooled, and can therefore not operate at high engine RPMs to develop lots of power. The ‘real’ bikers in the forums believe cruisers are slow because the owners don’t know how to ride.

How much HP does a 1000cc bike have?

1000cc Motorcycles: For 2-cylinder engines, expect to get about 80 to 100 HP. However, a 4-cylinder engine can get up to 180 to 320 HP for some ultra-fast acceleration.

Why do motorcycle engines rev higher than car engines?

That means in the context of a question about why motorcycle engines rev higher than car engines, you are wrong in saying the reason the bike engine revs higher is because of the stroke, it is because the stress on the internal components of the bike engine are lower.

Why does a 1000cc engine have more hp than a motorbike?

While a 1000cc engine in a bike needs little for that purpose, plenty of power to move up the rpm range for better HP. They’re much smaller, and can therefore spin much faster. HP = torque x rpm. Thanks for the lesson, but you really don’t understand this “very complex subject”. You have a very basic understanding.

What would happen if you put a car engine in a bike?

A high revving I4 like you would find in a 600cc sports bike has 150cc cylinders. Even if you shortened the stroke and increased the bore of the car engine the pistons would be much larger and much heavier than the pistons in the bike, so the car engine would still have higher stress for the same rpm.

How do you increase the RPM of a small engine?

If you want a small & compact, lightweight, engine, keep the cubic capacity small, & hence the rpm will need to increase to achieve the same total ‘flow’. The more you can compress the charge prior to ignition, the greater the relative expansion, & the more power that can be absorbed from the process.
