PBR Twin Color Crown ultra-light anti-mud hard anodized aluminum 489 - 520
Designed for the terrain, this PBR crown combines lightness and robustness for motocross, MX, and enduro riders. Precisely machined from 7075 T6 aluminum, it features a hard anodization that protects the surface and enhances the Twin Color finish (green).
The tooth geometry has been designed to facilitate mud evacuation and minimize friction between the chain and crown, thus contributing to better transmission efficiency on muddy surfaces. Strategic cutouts lighten the part without compromising its mechanical strength, reducing unsprung mass for a more agile motorcycle behavior.
Careful finish and colors suitable for racing machines: a choice that is both aesthetic and functional for those seeking durability and off-road performance. Ideal for 520 transmissions — check the diameter and number of teeth before installation. Frequent compatibilities: KAWASAKI KX 450 (2026), SUZUKI RM-Z 250 (2006), KAWASAKI KX 450 X (2024).
