small-capacity bikes rev higher because
they need to have higher specific power output in order to maintain decent driveability
. they can afford to have higher rev limits because they have a small stroke compared to most car engines and so the piston speed & acceleration is much lower at a given rpm.
Why do motorcycle engines rev higher than car engines?
Motorcycle engines tend to have smaller and lighter parts than car engines, and while this limits their maximum throughput, it allows for higher RPMs, which allows for more power
.
Why do motorcycles rev so loud?
Motorcycles are so loud because of the size of the muffler most of them have, the length of the exhaust pipes and the lack of residence time the air and exhaust have to slow down, and because the engine is open to air and atmosphere with no engine compartment encasing and stifling the sound.

How high do F1 cars rev?
Currently, F1 engines spin up to
15,000 rpm
, whereas older, much-loved V8s and V10s topped out at nearly 20,000 rpm, creating an incredible shriek that defined the sport. An increased rev limiter isn’t a replacement for adding cylinders, but it could help sweeten the sound of F1’s V6s.
Why is 7000 rpm the limit?
Petrol engines usually redline at 7000-8000 RPM while diesel hits the peak at around 4500 RPM. This is because
diesel engines are not made for high RPM in the first place
. They are slow to combust than petrol and are mainly focused on more torque rather than RPM.
Does high rpm hurt engine?
Will High Rpm Damage The Engine?
A high rpm can damage your transmission over time, even if it is extremely low or high loads
. The high rpm also causes wear on the bearings and oil seals, which results in faster fluid breakdown.
Why do people on motorcycles rev their engines?
And, after reading a whole bunch of stuff about the matter, I found a pretty clear online consensus: Motorcyclists rev their engines
because they don’t want to stall
— especially with new or recently repaired engines that have not been “broken in” yet — or, in the cases when that probably isn’t an issue, because they’ …
Are loud motorcycles actually safer?
Sometimes, it seems there are almost as many myths about motorcycle safety as there is genuine advice. And one that persists is the notion that ‘loud pipes save lives. ‘ I.e., the louder your motorcycle’s exhaust is, the safer you’ll be. But
a new study has thoroughly debunked that
.

Why do race cars rev so high?
Lower piston speeds means less stress on the connecting rods and crankshaft as well as acceptable flame propagation speeds
, allowing the engine to rev even higher. Also, by having a wider bore, you can have larger intake and exhaust valves, leading to better airflow at high RPM.
What is the highest revving V8 engine?

Why do rotary engines rev so high?
Rotary engines are also known for revving high, and that’s because
in eschewing pistons altogether, they don’t have any reciprocating mass, just rotational mass
. You also need lots of air, which is why the Honda S2000 employs variable lift on its intake valves.
Are Indy cars faster than F1?
