Manufacturer's ref: 112U-520-51GEHA

The Renthal Ultra-Light mud-resistant crown 112U made from 7075 T6 aluminium combines lightness and strength for motocross, MX, and enduro riders. Precisely machined, its specific tooth design facilitates mud evacuation and limits friction between the chain and the crown, providing a more responsive transmission on heavy terrain.

• Material: 7075 T6 Aluminium, hard anodised
• Number of teeth: 51 (pitch 520)
• Type: Standard 112U, aluminium finish
• Design: mud-resistant profile + strategic cutouts to reduce weight without sacrificing strength

The hard anodisation reinforces the surface and enhances aesthetics while protecting against wear. The lightweight cutouts and optimised machining help reduce the mass of the final drive, which can contribute to better bike responsiveness and more uniform chain wear. Designed for muddy and demanding environments, this crown fits on 520 transmissions where performance and reliability are paramount.

Compatibility examples: KAWASAKI KX 450 X (2026), SUZUKI RM-Z 250 (2006), KAWASAKI KX 450 (2026). Ideal for riders looking to optimise their bike's performance in off-road conditions.
