Manufacturer Reference: 702 48 L
The PBR Ultra-Light 702 crown in 520 aluminum is aimed at demanding riders, whether from motocross or roadster backgrounds, who seek a lightweight and reliable component for their transmission. Drawing on experience gained in competition, this crown combines precision machining and carefully selected materials to maintain performance on both track and road.
The manufacturing process follows strict controls and uses high-quality raw alloys, which gives the crown good resistance to corrosion and abrasion while reducing friction in contact with the chain. CNC machining ensures uniform tooth profiles for clean and consistent engagement.
