Lambretta Drive side sprocket 20 tooth, Race-Tour MB

This is a top quality MB front sprocket with 20 teeth.

It  ideal for use with a long chain.

If you are using a 47 tooth rear sprocket then you would need to use a new 83 link chain.

The combination of 20/47 only really works with the GP200 gearbox and gives a final drive of 4.7 - depending on your chosen exhaust this may not allow your engine to pull well in 4th gear.
