"O" Ring chains.

czowner · 06-29-2008, 04:55 PM

I hunted out an "O" ring 428 chain, not an easy task. I fitted it along with some new sprockets and drive pins 1500km ago, here's the good bit; I've not had to adjust it again after fitting.

Next time you run the bike into your top end, see if you are hiting the same top speed as you used to with the old non O ring chain. I am seeing a slower top end and speed with my new 520 RK XOS chain. I just talked to a old friend today on the subject and he personaly has seen a significant power loss going to X ring chain on 2 different atv's. Now Im begining to see why the DID 428 non O ring chain I bought got the "raceing" lable. Soon as I get some non o ring 520, I'll run my hill and see exactly what the deal is and post it. The RK520 X ring needed tightening after the first 65 miles!

Going to a 520 from a 428 is a lot more rotating mass. That's probably where you lost some top end.

As far as I'm aware speed is no different. I did consider going to a 520, but I think it's a bit heavy duty for a mere 18bhp bike, and as Red points out it's more weight for the motor to move.

According to the D.I.D. tensile strength chart for their chains, there is only 1 chain they make, the 248V that is suggested for a 250 cc engine. All the other 3 DID 428's are suggested for 125cc engines. On the other hand, the 520NZ and 520S are both suggested for 250cc engines. The 520MX is rated out to a 500cc engine. So you see there are different wieght 520's that can service out to a 1000cc engine such as the 520ZVM2.
The 250cc D.I.D. tesile rateings for the 520S(7,200), 520NZ(8,220) are both considerably higher than the 250cc tensile rateing of the 428V (5,340). The DID 248 Racing chains of NZ,S, and H are all 125cc Suggested. They claim their ER,ERT,MX and NZ hi performance racing chains are all light weight and NON o ring except for the ERT2 endurance/Road racing. I only wish they would give a physical wieght also for comparison. The point is, if you want a long lasting chain, the 428 "shouldnt" come close to a comparable 520. The thing Im finding out is the O-ring resistance factor. It looks like they are primarily for long continuous use without lub intervals are mud puppy work in the ATV arena. For a commuter with a occassional dirt trip its becomming clear to me I think I made a mistake buying a X ring chain on a entry power level bike. Just how heavy a difference there is between the 2 and that relavance toward performance is something I look foward to finding out!

For what it's worth Dad and I got over 8k miles from our stock 428 chains if I remember correctly. The 428H listed in the parts threads seems to be fine too.

dieselhead · 07-01-2008, 12:28 AM

8K on the OEM rubber band is exceptionaly good, The RK520-XOS box said its "guarenteed?" for 20K. But thats a 100 dollar chain! I agree, the 428H chain may be the best bang for the buck with all things considered.
JUST found this spec chart and added it to the chain sticky
http://www.didchain.com/specs.htm AND the weights are in there!

Funny old world, that's how long my chain lasted as well.

Just figured id kick this subject back up to what I found out in my comparison between X ring and Non O ring chain. I posted it in the Chains 101 sticky. Its pretty drastic.
