Two-wheelers with belt drives

As we all know that motor cycles make use of chain drives as means of transmitting power from engine to rear wheel.

Now i was wondering what would happen if this chain-sprocket thing was to be replaced by belt and pulley system.

it will have its own advantages : it will be lighter, noise levels will be reduced, and it will make the vehicle designer's job easier.

Does it have any advantages though ? is this feasible ?

No, belts can't be used due to following reasons:

- Belts have much less strength than chains
- Susceptible to slip, speed ratio doesn't remains constant
- Periodic retensioning is required
- Upper limit on power and speed
- Belts deteriorate on exposure to lubricants
- Limited life and need periodic replacement

can you elaborate on this ?

Belt drives depend on friction. Things may happen to reduce this at a critical moment leading to accidents. mechky's elaboration is explicit.

speed limit is about 2000m/min and power limit is about 60kW

Some cars use timing belts. Some motorcycles also use belts. And there seems to be no problem.
Please correct me if I am wrong. 😕

Yes those are belts. those are ribbed belts. they are basically used for timing. they seem to make good substitutes for chain drives in those harley davidsons .

So belts can be used, right?

ofcourse. as you can see that they are already being used.

Yes. I do recognize that #-Link-Snipped-#. 😀 However, the first respond to your topic is a "no". So, I wonder if what #-Link-Snipped-# says is true.

I never really know the reason why, but I know that many have substituted chains with belts (...and of course they change the sprocket too).

i first said no, because mechky gave strong reasons. But now since belt drives are implemented and the bikes are running normally, then there is no point in disagreeing

Yes, toothed belts similar to timing belts are appropriate.
