JT steel rear sprockets are manufactured using only the finest grade of C49 high carbon steel.

Two styles of rear sprocket were used on the DR350. The 90-95 'S' and 'SE' (street legal) models have a cush drive hub. The 96-99 'S' and 'SE' as well as all of the 'dirt only' models have a non-cush rear hub. Select your sprocket accordingly. If you are not sure, look at your bike. If the sprocket is bolted directly to the wheel hub you have a non-cush model. If your sprocket is bolted to a separate sprocket carrier you have a cush drive model.
