PBR steel sprocket, designed for 520 transmissions that demand robustness and precision. Derived from PBR's competition experience, this standard sprocket (type 823) is machined from an 18NCD5 steel alloy, chosen for its abrasion resistance and corrosion resistance. Ideal for motocross riders and roadsters looking for a reliable drive component during replacements or restorations.
This sprocket stands out due to a strict manufacturing process that ensures a consistent tooth profile to minimize jolts and premature chain wear. Its finish aims to reduce friction in contact with the chain and prolong the lifespan of the transmission without overpromising unverified gains.
Compatibility (examples): HUSABERG FE 350 (2014), HUSQVARNA WR 400 (1989), HUSABERG FS 650 E /6 (2008). Suitable for standard replacement mounts on motocross and roadster motorcycles equipped with a 520 transmission.
