Counter shaft seals can wear out over time. Replace it with a genuine Yamaha counter shaft oil seal.

This is a genuine Suzuki part. We recommend installing a countershaft seal retainer to prevent the countershaft seal from popping out while riding.

OEM Suzuki seal retainer for the DR650. Simple insurance against your countershaft seal popping out of its bore.

This is not a common problem but for those folks who have had the seal come out it has proven to be quite difficult to get it to stay in place. This steel retainer eliminates any possibility of the seal coming out and ruining your day by coating your rear tire with oil.

Polyurethane drive cushions for the KLR650. 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 rubber counterpart.

The KLR650 is rather hard on the cush drive rubbers. Replace these any time you feel excessive play in the sprocket hub. Excessively worn dampers can cause the cush hub bearing to fail - which will ruin your sprocket carrier.

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.

Replace these any time you feel excessive play in the sprocket hub.

Excessively worn dampers can cause the cush hub bearing to fail - which will ruin your sprocket carrier.

Sold as a full set.

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.

Now you can have minimum output shaft wear, minimum chain drive wear with the FRITZCO DRIVELINE sprocket. The design of their sprockets provide correct chain alignment, allows for full spline contact with the XR650L's output shaft, fit the counter shaft either way, and straight up no hassle installation with the OEM two bolt retainer and fasteners (except 13 tooth that comes with it's own quick change retainer). Their sprockets are machined from alloy steel that is comparable in every way to OEM Honda and the best offered by other manufactures. The sprockets are then given a heat treatment that provides a compatible sprocket for the Honda output shaft and longest wear life possible.

A way to double the sprockets life would be to have a sprocket that fits on the shaft either way so both sides of the teeth can be used. Bear in mind you can't wear one side of the teeth all the way through, then flip the sprocket, and expect double life. You must reverse when a normal wear pattern develops.

A 16 TOOTH SPROCKET IS THE BIGGEST FRONT SPROCKET THAT WILL RUN WITH THE STANDARD 110 LINK CHAIN AND 45 TOOTH REAR SPROCKET ON A XR650L* THE OEM COVER WILL REQUIRE MODIFYING TO USE THE 16 TOOTH SPROCKET ON YOUR XR650L.
