Super Service and Great value
New riders think a chain is a chain but after you replace a few after only a few riding hours price becomes the second variable. Dennis Kirk sells this great RK heavy duty chain for a great price. Properly cleaned and adjusted I expect alot of riding time before I'm in the market for another.

Good Chains
RK chains are as good as you can get. We have alot of sand that eats chains, these seem to out last the others that we have used.
