Looking for older KTM sprocket

[Gary B.]

I have a 1990 600 LC4 with a Sidewinder sprocket #5252 48T. If my memory serves, the rear hub has been replaced with an older unit. I'm waiting on a reply from Sidewinder. I also have a Sprocket Specialists sprocket for this same bike, but can't find a part# on it. Anyone have any thoughts on this? My local KTM dealer isn't real easy to work with and another local (non-KTM) dealer is stumped. :think:

Nothing there is pre-1990. I'd like to cross-reference the SideWinder #5252 into other brands, unless the SideWinder piece is still available. As I said, I'm positive this rear hub is off an older bike.

 

[Gary B.]

I found a # on the other sprocket. 269 48. It could be a Sunstar sprocket.

 

[VintageDirt]

Yes! That's the same number I just found here http://www.sprocketspecialists.com/PDF/2004catalog.pdf

I'm waiting for a call back from one of our local wrenches, he closed his bike shop here years ago and I know he has some Renthal sprockets for older KTM's still kicking around.

 

[Chili]

Ok, got a call back. He has Renthal's in 48 and 50 tooth that should cross reference to that Sprocket Specialist one you listed (269). Drop me a pm if you're interested and I'll pick them up and get them shipped for you. Last I saw them in his shop they were not packaged but loose (bought in bulk type scenario) but obviously new. Price was very attractive as well.

*Between 90-99 KTM made a 600 and a 620. The LC4 model is a 620 of 1995 vintage or later.
The #269 sprocket is for pre-1990 600 models disignated with either MX, or ENDURO nomencalture.

So, there is confusion if you starte you have a 1990 600, that is an LC4. That doesn't jive.

Now, if you do have a 1990 600, the proper sprocket would be the #925 (Sprocket Specialists #).
*(this info is from Sprocket Specialists...I cannot vouch for it's precision)

There is another way...
If you take some measurements, I can make certain you get the proper sprocket for your bike. (~$37)
I need the following:
How many bolt holes?
What is the diameter of the bolt holes?
What is the diameter of the hub circle (big hole in sprocket)
What is the mounting hole diameter (imaginary circle going through each bolt hole center).
What is the number of teeth you desire?
With that info, I can tell you what sprocket you have, and have it built.
This would only be an American made sprocket, hand machined by an American craftsman. If you are looking for an imported stamped sprocket, disreguard.
:)

Jay based on the measurements we took from a Renthal #161 Sprocket, he is in fact running an older hub.
