RENTHAL Ultra-Light Mud-Resistant Sprocket 154U - 520 (47 Teeth)
Designed for demanding riders, the RENTHAL Ultralight™ sprocket combines lightweight construction with durability. Machined from 7075 T6 aluminum, it offers excellent mechanical strength while minimizing unsprung weight. The "mud-resistant" tooth profile facilitates debris evacuation and helps reduce friction losses between the chain and the sprocket, making it useful in muddy terrains.
- Material: Anodized 7075 T6 aluminum (silver finish)
- Teeth: 47 teeth, pitch 520
- Design: Strategic cutouts to reduce weight without compromising strength
- Usage: Designed for off-road (MX, SX, enduro) and adaptable to some roadster applications
The anodization provides enhanced surface protection and a durable finish. The precision machining and mass reduction in key areas contribute to decreased transmission inertia, resulting in a more responsive feel during acceleration and controlled chain wear. Standard 520 part, designed for simple and reliable installation.
Manufacturer Part Number: 154U-520-47GRSI
- Common fitment examples: HONDA CRF 450 RX ENDURO (2026), BETA RR 250 2T ENDURO (2016), HONDA CRF 450 RWE (2026)
