DID 520MX chain

Just wondering how many of you guys use this chain and what you think of it, also will this chain fit an 09 yz450 in terms of width clearance around the countershaft sproket/engine case, don't want it rubbing on my engine case.

Thanks in advance

I have better luck with RK. They do not stretch as much

The YZ450 doesn't have a particular problem with clearance between chains and the case. If you don't align the rear wheel dead straight, you can have a problem with the chain hitting the frame, but that will happen even with the narrowest non-sealed chains.

For longevity, it's very hard to beat the Regina ORN6.

How does this chain compare to other non o-ring chains.
