BikeMaster KTM Front Sprocket 520 15T

What you get here is a single front sprocket, specifically a 15-tooth sprocket designed for a 520 chain size. This sprocket is built from 20CrMnTi steel, which is then shot peened to help it wear better over time and heat treated for extended durability. It’s made to fit a range of KTM motorcycles, including models like the 690 Duke and 640 Supermoto.

The shot peening process helps create a more consistent wear surface, which means you should get good mileage out of this sprocket. It’s designed for a direct fit, so installation should be straightforward, and it works with BikeMaster chains if you're looking to replace your chain at the same time.
