RENTHAL Front Sprocket 257 - 428 13T

Renthal sprockets and crown gears are developed in competitions in the USA. They are precision machined from high-quality materials. These transmission components limit friction in order to transmit as much power as possible to the rear wheel.

• Anti-mud: improved evacuation of mud for maximum and constant efficiency
• Made from a nickel-chrome-molybdenum alloy: greater strength
• Lighter than original parts
• An excellent compromise between efficiency and longevity
• Recommended for race use

Suitable for:
