✨Renthal 491--415-36P-BK Ultralight Rear Sprocket 36T KTM 50 SX 2014–2025
The Ultralight rear sprocket is engineered to deliver efficient power transfer and reduced rotating mass on mini and electric motocross bikes. CNC-machined from premium 7075-T6 aluminum, this Renthal Ultralight rear sprocket is significantly lighter than steel while maintaining the strength required for aggressive riding and competitive race conditions.
Designed for performance-focused youth motocross and electric models, the Renthal Ultralight rear sprocket features an optimized tooth profile that allows the chain to roll smoothly on and off the sprocket. This design reduces friction, noise, and wear, helping extend chain life while improving throttle response and drivetrain efficiency during racing, practice, and routine maintenance.
