This is a top quality BGM front sprocket with 17 teeth.
It is mostly used to increase gearing and improve the top speed of your scooter.
Sorry, these are no longer sold. Please see our selection of Indian sprockets.....
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.
