I recently started shopping for a new chain and sprockets and I am going with the IronMan 14/48 for my 600 and I need an education on chains. I'm seeing O-Ring, X-Ring, and Z-Ring. What are the differnces? I want the best chain I can get. Any suggestions would be appreciated.

I've personally never heard of a z ring but an Xring last 1 1/2 times longer than an oring.

In past, I had excellent luck with Regina Gold o-ring chains. They hardly stretched at all on a KTM300EXC in muddy eastern conditions. This topic was just discussed (check recent posts a few pages back) and Ironman and Qadsan both recommended the DID ERV2 chain. They seem to know there stuff and I guess Ironman puts on lots of desert miles. Here is the link to those posts: http://www.thumperta...5/o/all/fpart/1

I am getting a new chain and sprockets and I have decided on a DID X Ring chain and Iron man Sprockets. I have a 1993 XR600R and wrote ironman asking which sprockets I should order. Here is what they had to say..

Stock gearing on that bike is 14/48. The only sprocket we have for that model is a 47 rear. The X-Ring is a very good chain and works fine with our sprocket. I would suggest getting the 47 and ordering a steel front from Sprocket Specialists or Moose.

Im a bit confused because lots of people have been recommending Iron Man and saying they use them. I would prefer Iron Man sprockets, am I trying to buy them from the wrong place maybe ??? I looked them up on

If not from there, Where can i get these magical sprockets for my bike ???


If you have no fear, you didnt go as fast as you could have ...

I have 47, 48, and 49 rear Ironman-in fact i have 3 48 tooth rears...!
Thats for a XR650R--but they are the same as the CR sprockets...i cant say for sure with the XR600 if the 650 and CR sprockets are interchangealbe-but i would guess they are-but check it out first...
If you want to go with the 47 rear--the difference is going to be small-although a bit noticable.

Hope that helps...!

I got a question while we are on the subject. I put Moose front and rear steal chromoly sprocket on my bike with a moose xring chain.(nice gold one too) When I spin the wheel on the stand the chain doesn't flow to well with the sprocket. Kind of like the links are too long/short for the sprocket tooth spacing. Anyone have this issue? Will it correct it self after a break-in?

I went through some of this last spring. I have a 48 Ironman rear and Titax front. I originally bought both front and rear from Ironman but the front would not fit. I found out later that they thought the 650R and the 600R used the same front sprocket but they do not- the 650R sprocket is like .340" thicker ( the "washer" with the two holes on it used to hold the sprocket in place won't slip past the grove in the shaft so yuo can't bolt in into place). I ended up buying a Titax front sprocket from rockymountainmc.com - all they had in stock at the time was a 14( you might also try the TT store)I am also using the DID X ring, great so far. Hope this helps.

Anyone know if XR600 and XR650 rear sprockets are the same?

I got the impression from the dude I talked to at Ironman that their rear XR600 and XR650R sprockets were the same but I don't know that for a fact. They sure seemed surprised that the 650R countershaft sprocket wouldn't fit my 6hunny.

The XR600R uses the flat style rear sprocket bolts, whereas the 400 and 650R use the conical shaped bolts. I'm sure the spacing is the same, so if you order the appropriate conical style bolts, you should be able to choose from a wider range of sprockets. Earlier XR250's (pre 1996) also used the low profile flat contact style bolts like the 600R.
