What is Chromoly 440 steel used for?
The front sprocket uses CNC-machined, heat-treated Chromoly 440 steel. The front sprocket teeth remain in repeated contact with the chain while riding. Steel is used here to prioritize load and wear resistance. If the old teeth are pointed or unevenly worn, fit a front sprocket with the same tooth count to retain familiar riding characteristics. Also inspect chain and rear sprocket wear so all three components work together consistently.
Selecting tooth count for your riding needs
Consider the front tooth count together with the rear sprocket currently fitted. Dividing rear teeth by front teeth gives the final drive ratio. When replacing a front sprocket, retain the tooth count if you are happy with the bike's current riding characteristics. This model is available with 17 teeth.
Checks before installation
Year 2012 appears in both name ranges, so confirm the sprocket using an output-shaft image. Inspect the shaft bore and retaining mechanism of the sprocket removed from the bike. A front view does not show all grooves and raised sections on the shaft-facing side.
