Renthal Aluminium Ultra-Light Self-Cleaning Hard Anodized 112U - 520 SprocketRef : RT00193A / 1121384

Manufacturer Ref: 112U-520-50GEHA

The RENTHAL Ultra-Light 112U crown in hard anodized aluminum combines lightness and robustness for off-road use. Machined from 7075 T6 aluminum, it offers excellent fatigue resistance while reducing unsprung weight — an advantage when the track becomes demanding.

• Configuration: pitch 520 / 50 teeth, standard type 112U.
• Mud profile: shaped teeth to facilitate mud evacuation and limit chain-crown friction.
• Hard anodization: strengthens the surface against wear and highlights the aluminum aesthetic.
• Strategic cutouts: targeted weight reduction without sacrificing rigidity or reliability.

Designed for motocross, supercross, and enduro, this crown is aimed at riders looking to optimize the responsiveness and traction of their transmission while improving the durability of the part. It fits on chassis that accept the 520 pitch and 50 tooth count.

Particularly suitable for KAWASAKI KX 450 / KX 450 X (2026) and SUZUKI RM-Z 250 (2006) models. A smart choice for those looking to lighten their chain-sprocket assembly while maintaining a precise handling on the track.
