PBR Ultra-Light Hard Anodized Aluminum Sprocket 4586 - 520
Developed based on experience gained in competition, this PBR sprocket combines lightness and durability for 520 pitch chain transmissions. Machined from high-quality aluminum, it features a hard anodization that enhances resistance to corrosion and abrasion while maintaining a refined stainless steel look.
Designed to reduce friction in the chain through careful finishing and strict manufacturing tolerances, this sprocket is aimed at riders looking for a good compromise between reduced unsprung mass and robustness for road or sport use. Simple maintenance: regular play checks and appropriate lubrication to optimize longevity.
Compatibility (examples): BMW S 1000 RR ABS (2014, 2016, 2018) — check fitment on your model before installation.
