RK Chain MRU420 U-Ring Clip Link

The RK Chain MRU420 U-Ring Clip Link is a clip-type connecting link designed for the 420 MRU series chain. The MRU U-Ring Chain features ultra-thin U-Ring seals that are less than half the thickness of standard O-rings, allowing it to maintain the weight of a non-sealed chain while offering over four times the lifespan of comparable non-sealed 420 chains. This reduces the need for frequent adjustments. With a tensile strength of 4,540 lbs and a maximum engine capacity rating of 150cc, this chain is suitable for street and off-road use on bikes up to 25 horsepower. It is an excellent choice for models like the Honda Monkey and Grom. The clip-type master link is included for easy installation.
