Lambretta Drive side sprocket 21 tooth, Race-Tour MB

This is a top quality MB made front sprocket with 21 teeth.

It's ideal for use with a long chain.

If you are using a 46 tooth rear sprocket then you would need to use a new 83 link chain.

The combination of 21/46 only really works with the GP200 gearbox and gives a final drive of 4.67 - depending on your chosen exhaust this may not allow your engine to pull well in 4th gear.
