Rk520 Mxz4 chain
Got this chain about a month ago seems to be good quality. Very little stretching. Would recommend this chain to others.

As expected
I did not notice any significant initial stretching upon my first day at the track.

RK 520
This chain is really nice! Super light compared to the stock chain. The difference between the RK and stock is this is not an o-ring chain so you'll need to keep it oiled. One other thing to keep in mind. This chain will stretch passed spec as soon as you take it out on the mx track the first time. Tighten the back to specifications and you'll be good for a while.
