We carry DMO Specialties rear drive sprocket adapters for all years of the BW350. The original rear sprocket for these bikes, Yamaha part number 2JN-25437-51-00, has been discontinued, and there are currently no direct bolt-on aftermarket rear drive sprocket available, so this is the solution. The beautifully machined part bolts up to the stock rear sprocket hub on these machines and allows you to run easy to find Honda 400EX rear drive sprocket, which we will soon offer below.
