Drive sprocket, 17 tooth
It is mostly used to increase gearing and improve the top speed of your scooter.
If you are using a 46 tooth rear sprocket then you would need to use an 81 link chain.
Depending on the specification of your engine your engine might not have enough power in 4th gear using a 17/46 set-up.
This is usually used with Li 150 gear boxes and 46 tooth sprocket with 81 link chain.
