.... what is a orn6 chain?


The Regina ORN6 is an O-ring sealed #520 racing chain that uses a press fit clip type master link. It's available under the Regina name, and also from MSR as the "MSR Regina ORN6". I don't know if it is still the case, but for many years, the Renthal R1 was a relabeled ORN6 sold at a higher price.

The ORS6 is an O-ring sealed chain that employs a riveted type master link, for those who prefer that. Regina also makes the ZRH and ZRD chains which use a patented variation of a multi-lipped seal in place of O-rings for those who want something upscale.

The Renthal R1 is a non o-ring chain. You are referring to the Renthal R3.

Correct, you don't want the added aggravation of a rivet link on a motocross bike. Rivet links are for high hp street bikes. I personally even run clip links on my street bikes, but I smear some RTV on the clip so it doesn't pop off as a little added insurance.

Depends on what you mean by "best". "Best" is a very much overused and fairly useless term.

The ORN6 by Regina (also sold as the Renthal R3 at one time, but at a very much higher price) is a very, very durable chain that's sold at a relatively reasonable price. If best means the most expensive, it's not. It also does not have the highest tensile strength on the market, either, but If you keep it correctly adjusted and clean, you won't be able to break it.

They last over a year, year and a half for me, and they keep the rear sprockets from wearing as fast because they just don't stretch.



Is the Renthal R3 still this chain Gray? Hard to find Regina stockists in New Zealand, but have come across the Renthal R3 (does seem to be a reasonable price however) - or have they changed - based on your comment above ("at one time").

I'm afraid I don't know that.

I ran a 520 on my R6 in '05 when I was road-racing, and at the time it made 116 rwhp on the dyno (after a shaved head, thinner head gasket, degreed cams, PCIII, full Yosh. etc. etc). While I'll agree that the dirt/debris is hard on a chain, I'll disagree that a dirt bike itself puts more stress on a chain than a 600 - simple math, it's putting more than twice the amount of hp through the same chain.


Your R6 also has a cushioned rear drive. The mx bike is directly mounted to the rear hub. Then you have the larger distance between the sprockets, and the increased slack needed to compensate for suspension travel.

If you want to talk stress in terms of "strengths of materials" then whatever bike puts the most tq to the rear wheel will handle the greatest stress.

If you want to talk stress in the context that it's being talked about here, the chain on an mx bike sees a much, much more "stressful" life than a road bike chain.

if you are looking for a good chain that fits in your budget i would go with the Primary Drive i have used one on my YZ45f and it has lasted me for two years here is a link where i got mine.
Primary Drive then in the search type chain that's how i found them.

I've had good luck with both the Regina ZR chain (higher end z-ring chain) and the Regina ORN6 chain.

my best luck has been with DID products, both drive and cam chains, but I haven't tried them all. You sort of get what you pay for.

RK GB520EXW This is the best chain that I have ever used. The GB stands for gold. If you want black then it is called a 520EXW.
