RENTHAL Ultra-Light Mud-Resistant Sprocket 189U - 420 (49 Teeth)
Designed for off-road, the RENTHAL Ultra-Light 189U sprocket combines lightness and durability for MX, SX, and enduro riders. Machined from 7075 T6 aluminum, it maintains high strength while minimizing unsprung weight. Its specific tooth profile facilitates mud evacuation and reduces friction between the chain and the sprocket, providing sharper handling in muddy conditions.
The anodization strengthens the surface and preserves aesthetics against abrasion from gravel and mud. The cutouts and tooth profile are designed to limit dirt accumulation, simplify maintenance, and maintain transmission efficiency.
Notable compatibility: specifically suited for HONDA CRF 150 R (2020/2022/2026).
