The Regina ORS O-ring chain is a whopping 3.4 oz heavier for a 116 pin chain than their premium non-O ring chain. At any given moment, there are only 8 O-rings in motion, and of those, only the four at the front sprocket are moving as much as 15 degrees. What drag? What the chain feels like on the stand does not translate into drag that can be felt on the track or trail, and I doubt it would add up to anything significant on a dyno. Name one with a tensile strength higher than than the 8100 lb tensile strength of the Regina ORS. Having trouble? The DID ERT is the only one I know of.

My Reginas run for about two years or better with very little of what you would really call maintenance to get them to do that. Hose them off, put a dry, non-sticky lube on them to prevent rust, that's it.

you mentioned the did also the primary drive 520 h racing chain on page 386 of rocky mountain catalog shows 8510 lbs. of tensile strength.

OK, then, now I know of 2. But tensile strength is less important than it gets made out to be sometimes. There are any number of guys out there running chains with no more than 5 or 6000 psi tensile ratings, or even less, who never break their chains, and probably won't. The limits of tensile strength are usually tested the most in cases where the chain has been set too tight to allow it to have slack throughout the entire range of rear suspension travel. If that happens, the chain can be subjected to huge forces as the suspension swings through the tight spot. Otherwise, power-on landings and times when the rear wheel is skipping around under full power do the most to test tensile strength. Usually, the true limits of a high end chain are never even closely approached.

These standard chains also have a higher average tensile strength than the Regina 520 ORS(520-ORS 7510 lbs ):

RK 520-MXZ 8800
D.I.D. 520-NZ 8220
D.I.D. 520-ERT 8470
Regina 520-RX3 7644
(there are beaucoup more)

Gray is correct in his last post though. And that very scenario is why lots of sprockets (and chains and bearings, etc...) get worn before their time. Just a slight bit too tight is all it takes.

In reality, even the lowest end chain will not see the full potential of force during any normal run. If all things are proper, including adjustment, there isn't a dirt bike that can create enough force to even come close to the yeild point of a chain side plate. A CR500 will maybe create 1800 lbs.

On high end chains, Regina, Tsubaki, and Diamond all have the lowest posted tensile strengths. But as stated, tensile strength is more of a marketing ploy than anything. Although, a chain that states a higher tensile strength is usually constructed of superior components. Higher meaning over 6000 lbs.
