RK Chain 520EXW XW-Ring ATV / Enduro

RK Takasago's 520EXW represents the pinnacle of off-road chain engineering, purpose-built for ATV and enduro applications demanding uncompromising performance. The XW-Ring seal system employs advanced Nitrile Butadiene construction with triple contact lips and dual convex stabilisers, creating three distinct lubrication reservoirs that shield against abrasion and lubricant loss in extreme conditions. Rated to 10,430 Nm tensile strength and suitable for machines up to 750cc, this premium chain delivers exceptional durability through heat-treated hi-carbon alloy steel, seamless rollers, and thermally crack-resistant side plates. Trusted by factory racing teams including FMF KTM and Duncan Racing, the 520EXW outlasts conventional chains by tenfold while maintaining superior high-speed stability and heat resistance. Clip-type master link included; available in 100-120 link configurations.
