PBR Twin Color Aluminium Ultra-Light Self-Cleaning Hard Anodized 702 - 520 SprocketRef : PBR01034A / 1096612006

PBR Twin Color crown made of ultra-light aluminum, designed for off-road competition (MX, SX, enduro). Its construction in 7075 T6 aluminum provides an excellent balance of strength and weight, while the hard anodization protects the surface and enhances the racing look in blue.

• Manufacturer reference: 702 53 TC4
• Number of teeth: 53 (chain pitch 520)
• Material: 7075 T6 aluminum, hard anodized
• Mud-proof profile: machined teeth for improved mud evacuation
• Strategic cutouts to reduce weight without compromising mechanical integrity

The tooth profile and Twin Color finish reduce the risk of clogging and limit friction between the chain and crown, allowing for smoother transmission on wet or muddy terrains. The cutouts decrease rotating mass, which is beneficial for acceleration changes and rear-end maneuverability.

Designed as a reliable upgrade part for off-road machines, this PBR crown fits 520 setups and pairs particularly well with machines like SHERCO 450 SEF-R, BETA RR 390 4T, or GAS GAS EC 250 F. A technical and aesthetic choice for those looking to enhance and lighten their rear end without compromising durability.
