Renthal Aluminium Ultra - Light Self - Cleaning Hard Anodized Rear HA - 520 SprocketRef : RT00444A / 1075636030

Manufacturer Reference: 224U-520-48GPPE

RENTHAL Ultra-Light mud-resistant aluminum anodized sprocket, designed for Cross and Roadster uses where every gram counts. Machined from 7075 T6 aluminum, it combines lightweight and mechanical strength for demanding riders who ride in mud and extreme conditions.

• Anti-mud tooth profile: facilitates mud evacuation and limits accumulation between the chain and the sprocket.
• Machined 7075 T6 aluminum: high rigidity and reduced weight to decrease rotational mass.
• Hard anodization: surface reinforcement against wear and a neat finish (purple color).
• Targeted weight reduction: strategic cutouts to save weight without compromising strength.
• Specifications: 48 teeth — chain pitch 520 — standard type.

This sprocket provides a technical response to the needs of off-road and sport roadster riding: better transmission responsiveness due to reduced inertia, easier cleaning in muddy conditions, and increased abrasion resistance. Compatible with 520 pitch drivetrains, it mounts as a standard replacement. Ideal for MX, SX, and enduro, it is particularly suitable for bikes such as GAS GAS ES 700 (2026), KTM 690 SMC R (2026), or DUCATI DESMO 450 MX (2026).
