This is a top quality made in Germany BGM front sprocket with 16 teeth.
It used to raise gearing and slightly improve the top speed of your scooter.
Sorry, 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 old stretched 80 link chain, or go for one of my chain tensioners and use an 81 link iwis chain.
