Yamaha BW350 Front Drive Chain & Sprockets Complete Kit

We carry front drive chain and sprocket complete replacement kits for all BW350 models. As the stock 530 size sprockets are no longer available and no other aftermarket alternatives are available, our kit converts the front chain drive system to a 520 size chain and includes a new steel front sprocket (engine mounted sprocket - stock 14 tooth size), replacement 16 tooth inner countershaft sprocket (17 tooth is stock), and a high-quality DID non-O-ring chain and master link (must be cut to length).

A spacer is included to keep the narrower jackshaft sprocket aligned with the output sprocket.  Please be aware that this kit will give your machine a slightly higher top speed as the inner countershaft sprocket is 1 tooth smaller than stock.
