125-200cc Chain for 125??

[PC.]

Does an 09' CR125 require a thin-width chain (like Honda 450R's do) or just a standard width 520 chain?

I have used all sorts of chains on the 125's, they all seem to work fine, no issues I am aware of.

I have a big wide standard o-ring chain on mine, I need to change the front sprocket, it is hooked a bit. I need a new chain Guide too.

Thanks!

I got a new 14T front if you're interested. I want a 13.

No way man I am not trying to set any land speed records...

I am really happy with my 13-52 gearing I have set up now. I have 2-3 slightly used 13's laying around from Shane and Kelly going to 12 tooth I think. Let me know if you need one.

I use D.I.D. narrow enduro racing x-ring chain on my wr150,it causes less drag and wear on the chain guide and has only required one adjustment since new approx. 400 off-road miles ago. Good stuff

I have been using the Parts Unlimited X ring on mine. No problems at all.

 

[CelticDude]

I've been using the x-ring also. What kind of chain lube are you using?

 

[Blakelpd5]

Also running parts unlimited chain. I spray some wd40 on it every two rides. I'm thinking I have over 100 hrs on this chain.

You really should put a smaller piston in that thing so it will rev higher, that way you can get the same top speed without having to gear it up. I did a 6th gear pull on my trail ride last week to test the JD jetting kit some more and came up with 64mph on the GPS... There was still a little more there but after blowing it up doing stuff like that I am a little worried about holding it tapped on gravel for that long. As you can see from the average speed on this ride I really don't need taller gearing. I hit 69mph on the same GPS just before I blew it up a year and a half ago, I can't remember if that was 13-50 or 13-52 gearing though.

I have been running a KMC o-ring chain for 137.2 hours and about 1900 miles, I installed it a few weeks before I installed the trailtech GPS. I spray it with WD40 after every wash and have tossed some chain lube on it maybe 4 or 5 times. I am still on the stock front sprocket at 151.2 hours, damn these bikes are easy on drive components. I swap rear wheels and sprockets back and forth between bikes it is hard to get a good idea on rear sprocket wear. Having to change the front sprocket every 2 years is going to break the bank...

I am with you, not too many dry lake beds in these tennessee mountains..... 125cc's are plenty.

I bought a GYTR (Yamaha's in-house aftermarket brand) o-ring chain for $41 + shipping off ebay. It's a re-branded Regina o-ring chain.
Should last me a good while.

I use Maxima MPPL, or Moose Chain lube and sometimes I use Maxima Chain Wax . Mppl and Moose Chain lube (not the Heavy Duty) are very similar. Won't hurt Orings and dirt doesn't stick. If you use Chain Wax. Put on while chain is warm and then let sit overnight to dry and take set.
