Whats the best out there in the o-ring/x-ring type?  By best, I mean the most stretch resistant and longest lasting. I'm not worried about any hp reduction from and o-ring/bigger/heavier chain.  Just looking for the heaviest duty and longest lasting.

I get excellent service from the Regina ORN6 .  They last me well over a year of desert and MX use, and I replace them when they are 1.5% longer than new, not 2%, as Yamaha recommends.  The resulting sprocket life from such a small amount of stretch is also impressive.

I use RK MXZU on my 450 and they last the whole season of MX racing and practice's. At the end of the year I still practice with it on but change it out along with new Vortex sprockets before the next season. Time wise..........this is usually 36hrs ride time.

36 hours?  In the season and a half I get from the Regina ORN6, there are 14 desert races that run roughly two hours each, plus an hour or so of riding the day before, plus probably a dozen ride days scattered in at what I'll call an hour each, just to be conservative.  So I'm looking at 54 hours a year times 1.5, which is 81 hours.  Even then, the only reason the last one got replaced was that the top and bottom edges of the plates had run over the guides so long that they were worn down to where the master link clip was flush with the edges of the plates.  36 hours doesn't seem like such good service to me.  Because of the lack of chain stretch, the rear sprocket usually lasts through two chains.

I run the Regina ORN6 as well and they are excellent. I had 131 hours on my last one when I took it to Baja. Put another 1,660 miles on it down there. It's finally time for a new one.

I'd stray away from primary drive, spent 2 hours in the back country fixing one that snapped on a buddies bike. It was garbage, the metal looked soft the way one of the links stretched and finally pulled apart.

Renthal, DID, and RK racing chains have all been good too me.

I've had good luck with the DID x ring and master than was riveted on. Pretty easy with the right tool and no worries like Gray experienced

It's not a worry.  I install them right, and the Regina master link is interference fit.  I've never lost one, although I have replaced clips that were badly worn. The chain plates were also worn to the point that rollers were starting to contact the guides. 

 

But, if one wanted a riveted master link version of the ORN6, it's available as the ORS6.
