Description
A 13-tooth front sprocket is the common starting ratio for a lot of Suzuki RM and RM-Z setups, and ProTaper builds this one to outlast the stock part it replaces.
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
- CNC machined and internally broached to tight tolerances for a precise fit on the countershaft
- Cut from case-hardened, core-refined chromoly steel for a strong tooth root and long service life
- Computer-engineered tooth profile helps cut chain drag and keeps power moving to the rear wheel
- Balanced design reduces vibration transfer through the drivetrain at speed
- Proprietary surface coating slows corrosion and wear compared to bare steel sprockets
- Manufactured specifically as a 13-tooth front sprocket for RM and RM-Z motocross models running a 13-tooth front
ProTaper builds this front sprocket for RM and RM-Z motocross models running a 13-tooth front, and the tooth count is fixed at 13, 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 13T 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.
