RK 420 MRU X-Ring Chain, 120 Links

Ships from our supplier in 2-3 business days, at your door in about a week.

RK's MRU is a lightweight, low-friction sealed 420 chain for the Honda Monkey and Grom. Its U-ring seal is less than half the thickness of a common O-ring, which lets RK build a sealed chain at the weight of a non-sealed one; RK quotes four times the chain life of a comparable non-sealed 420 chain and fewer adjustments.

Finish is RK's black scale: black inner and outer plates with gold pins and rollers.
