Description
Sharing a bolt pattern across Yamaha and Kawasaki motocross bikes, this ProTaper 12-tooth front sprocket gives riders on either brand the same race-proven part without hunting for brand-specific numbers.
Stock front sprockets on most powersports machines are made to a budget, not to a race schedule, and they show it after a season of hard riding. ProTaper addresses that with a purpose-built replacement engineered around real load data instead of assumptions.
Features and Benefits
- Precision broached and machined to hold consistent tolerances from the factory
- Case-hardened chromoly steel construction resists rounding at the tooth tips under load
- Lightening holes trim rotating weight without giving up structural strength
- Self-cleaning mud grooves shed dirt and debris so the chain keeps tracking cleanly
- Protective coating helps the sprocket resist wear and corrosion between cleanings
- Manufactured specifically as a 12-tooth front sprocket for shared-bolt-pattern Yamaha and Kawasaki motocross models
ProTaper builds this front sprocket for shared-bolt-pattern Yamaha and Kawasaki motocross models, and the tooth count is fixed at 12, so the ratio math on your bike stays predictable from the first ride to the last. Riders swap sprockets to chase acceleration off the bottom or top-end pull on faster tracks, and having a dependable 12T option means you are not guessing at how a used part will hold up. This is not a graphics kit or cosmetic upgrade, it is a drivetrain component that takes direct load every time the throttle opens, so the metal and the machining behind it matter more than the price tag.
Why buy ProTaper from IPD Racing
IPD Racing has stocked and raced ProTaper drivetrain parts since 2005, and this sprocket is the same part number our own mechanics reach for when a customer’s bike comes in with a stretched chain or rounded teeth.

Verify bolt pattern and chain pitch against your specific model before ordering, and ask IPD Racing if anything looks off.
