The cush hub (sprocket carrier) bearing leads a tough life. This is especially true if your cush rubbers get old and soft. They can allow the chain to pull the cush hub sideways putting a twisting load on the bearing. If there's any question about the condition of your bearing replace it now with this double sealed bearing and quality seal.
High Quality chain. Will need to be cut to fit your sprocket combination.
All of these chains come with a clip type master link
A real Heavy-Duty Chain Guide manufactured from 5mm (3/16") thick 5052 Aluminum. This guide will take a pounding and continue to put that chain right on the sprocket. The rub block is machined from UHMW plastic and can be positioned to fit just about any sprocket available for the DR. These are powder coated black for a great look and additional protection.
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.
High quality steel front sprockets.
The DR650 is rather hard on the cush drive rubbers. Replace these any time you feel excessive play in the sprocket carrier hub. Excessively worn dampers can cause the cush hub bearing to fail - which will ruin your sprocket carrier. Sold as a set of 6 rubber dampers.
Polyurethane drive cushions for the DR. Polyurethane has a higher abrasion, cut, and tear resistance than rubber as well as much better resistance to chemical breakdown. This will offer longer life and better damping when compared to the stock rubber cushions.
