The RK 520 EXW Drive Chain is designed for riders who want reliable power transfer, long wear life, and consistent performance in harsh off-road conditions. Thanks to its pre-stressed and pre-stretched construction, the chain maintains more even load distribution, helping reduce stretch and cutting down on frequent adjustments.
Built from high-grade medium carbon alloy steel, with shot-peened and heat-treated components, the EXW series is made to handle high speeds and extreme heat—ideal for powerful off-road machines and aggressive riding. The W-Ring sealing helps keep lubrication where it belongs while blocking dirt and grit, extending chain life and improving overall drivetrain efficiency.
Key features:
✅ Pre-stressed & pre-stretched for equal load distribution and minimal maintenance
✅ Shot-peened & heat-treated alloy steel for strength and durability under hard use
✅ W-Ring sealed design to resist contamination and extend service intervals
Benefits of use:
🔹 Less adjustment over time thanks to reduced initial stretch and stable performance
