Supersprox Parts & Accessories

Supersprox have been producing motorcycle sprockets since 1959 — originally Welsh, now the biggest aluminium sprocket maker in Europe and North America. The Stealth hybrid line runs an aluminium inner ring with a hardwearing steel outer for the weight saving without the wear penalty, and the all-steel SCM-435 case-hardened sprockets are spec'd where ultimate longevity matters more than weight.

Mostly relevant on chain-driven Sportsters and chain-conversion builds rather than belt-drive Big Twins. If you're running chain final drive, this is precision-engineered sprocket work at sensible money.
