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.
