The Renthal 520 R33 Drive Chain is built for riders who want dependable power transfer and longer service life in harsh motocross and enduro conditions. Instead of a traditional O-ring design, it uses Renthal’s SRS (Self-Regulating Seals) ring system, helping retain lubrication while reducing friction and wear over time. The result is a chain that stays smoother for longer and stands up better to roost, mud, and repeated high-load impacts.
To boost durability, the chain is manufactured using the proven quad-riveting process from Renthal’s R4 range, and it features high-carbon alloy steel pins, solid bushings and rollers, plus shot-peened plates and rollers for improved fatigue resistance. Installation is also made easier thanks to the updated hollow-end rivet link design, which does not require a Quad Stake Rivet tool.
Key features:
✅ SRS (Self-Regulating Seals) ring system for increased longevity (no traditional O-rings)
