Product Description
Maintain perfect power transfers and factory performance margins on your youth race bike with this Genuine KTM OEM Front Countershaft Drive Sprocket. Stamped and machined directly by KTM to exact original blueprints, this 13-tooth replacement sprocket serves as the optimal choice for restoring factory-spec final drive performance or replacing a heavily hooked or worn drive gear. [1]
Constructed from heavy-duty high-carbon structural alloy steel, this sprocket undergoes local thermal induction hardening to ensure deep surface resistance against premature teeth rounding. Unlike universal aftermarket options, this genuine component features perfect spline tolerances matching KTM's transmission output countershaft, eliminating erratic chain tracking, vibrations, and premature output shaft spline wear.
- KTM Factory Genuine Quality: Offers exact material tolerances, specialized geometry, and case hardness specified by the original manufacturer. [1]
- Optimal Gearing Layout: The 13-Tooth design restores or preserves the original torque response and acceleration curve of your 50cc youth machine.
- Precision Spline Tolerances: CNC computer-cut interior splines provide a perfectly true concentric rotation, safely protecting vital internal engine components from premature wear.
