Mid level chain
Wanted an o-ring or x-ring chain but RM did not have any for 420 size chains. Bought the cheap RM brand and it stretched like a rubber band. This one is holding up much better.

Best 420 chain on the market
I'm a bit of a chain nut, because they have become so expensive, you better make the right choice or be disappointed and broke. I've been disappointed in the past, so when my kids got KX mini's I researched chains to find the right ones to rely on. I also wondered about the 428 chain conversions that so many people say you need, but that turns out to be false. My researched showed this RK 420MXZ chain to be the strongest 420 chain on the market. It beats ALL versions of DID, EK, Renthal, and every other chain I could find. It's also stronger than all but one or two 428 offerings, and those 428's beat it by only like 300 PSI (out of like 4200 psi if my memory serves). Not worth the weight! It's also stronger than most other company's 428 chains that weigh more and rob power. I buy the GB gold version because I think the plating helps with rust resistance, but this chain is the same without the gold coloring for a little less money. ALL chains stretch a bit at first. This one has pulled my 260 lb behind around the yard and at WOT on the ice for many laps, and I am extremely happy with it. No issues. Skip the marketing hype and look at the data the chain makers publish. You'll come to the same conclusion.

Good chain
Good value for the price. Seems to last. Son is wearing chains out faster due to more aggressive riding. I think this chain wears well for the money.

Good for the price
This chain is worth the money but if I had money to spend on a chain I would just buy a Renthal I expected more power that's the only reason I gave it 4 stars but overall a excellent product!
