RK EXCEL BL420-MRU DRIVE CHAIN BLACK
Ultra-light sealed performance meets bulletproof durability. The RK EXCEL BL420-MRU features proprietary Ultra Thin U-Ring seals—less than half the thickness of standard O-rings—giving you sealed-chain protection without the weight penalty. Run 4x longer than comparable non-sealed 420 chains, fewer adjustments, and serious street credibility.
Built for 150cc street and off-road machines up to 25 HP, this chain locks down 4,540 lbs of tensile strength in a featherweight 1.74 lb package. 17.1mm max width, clip-type master link included. When reliability matters and weight kills performance, the MRU delivers both.
