Work great!! From 31mph,now it’s running at 40mph,so it gave me 9 mph,make sure that your bike have enough power to launch it!!

I topped out at 43mph with a 80cc 2 stroke on a 26in wheel I highly recommend buying the pull starter because it will be hard to get it started sometimes . You will also need to retro fit the sprocket to a bracket because not all fit

I got the smaller sprocket to make the bike have faster top speed but the motor does not have enough power to use it.

At 5’9 I weigh 124 pounds and this gear allows for the perfect balance of top speed and acceleration. A go to choice if you’re a light person.

Got my max speed from 27 to 32. Not bad for a motorized bike i think.
David Schubert –
I have this gear on a 66cc stroke from bikeberry.com and have hit close to 60mph have to able to feed the motor and a good pipe matters i got a 20+mph with just a few bolton parts

You better have some power if you’re looking for speed
David lavergne lacasse –
It’s ideal for my bike frame and fit m’y wheel hub with the little space I have Between the frame for the chain but I have to reach almost 20 kmh before disengaging the clutch tink its more appropriate for a small wheel I have 20″ fat bike wheels and the engine seems to strain slightly but very fast surely with some engine modification will be perfect I think

It’s a good beefy sprocket and it handles 60 plus MPH
