Reliable and long lasting chain

Comments On Mar 05, 2013:I run these chains simply because they are cheap, reliable, and there are no fitment issues regarding clearances around the countershaft sprocket. I ride moto and occasionally hit the desert or a trail ride. Id wager to say an o-ring chain may be a better buy if you really abuse your bike in mucky wet conditions, but with the type of riding i do, these work perfectly.

best i've found

Comments On Feb 21, 2012:Have tried various chains on 250 four strokes and 450 four strokes. Have standardized on ERT2 because, after the initial little bit of stretch, the adjustments STAY PUT. With other chains I am forever having to adjust a bit.

low rolling resistance

Comments On Jan 17, 2012:I have been one to use oring chains in the past. I had one on a 1999 yz125 that I bought new back then. My buddy told me to switch to a non-ring chain. The first ride I immediately noticed more responsiveness and overall power with an overall smoother feel.
After that experience, I looked a little closer at the oring vs non-oring chains. The oring chains do not move up and down in the links as easily. Try the same on a good quality non-oring and the links virtually fall all over one another. Its a very significant reduction in friction.
I also have a cbr929rr with some mods. It has about 140 rear wheel horsepower. On this bike I use an o-ring chain of the 520 size. This is the same did ert chain oring chain that you would use on your dirtbike. It can handle all of the power of my streetbike. If you look at the tensile strength difference between the did oring and non-oring, there isn't a huge difference. The 2008 crf450r that I ride has around 50 rear wheel HP. It really doesn't need the o-ring especially when the non-oring has so much less friction.
