950 Supermoto Chronicles - Page 521

Last week I traded my KTM625SXC for a KTM 950 SM. Twice the power-twice the fun!

I have a Bridgestone 180/55-17 rear tire and it is very close to the chain guard, it is also clear wear marks from the chain in the edge of the tire.

Is this normal or have the previous owner screwd something up?

It has never been a problem for me on any of my SM's....but it also doesn't happen on my 950...

I doubt that's a problem. I don't have any clearance issues on my 950sm, but the 450exc I turned into a supermoto has bad chain rub on the tire (many do) No issues there either. That's a thick area of the tire.

My local dealer actually keeps a jack plane on hand specifically for shaving that area down on tires used for sumo conversions.

Post a pic of the area and we can go from there.

Not sure there should be LC8 chain rubbing on the back tire. Especially with a 180/55, since it is stock width. The comments about the 450 are accurate and I, too, shaved to keep the chain off the edge of a 450SMR tire. The 950 has a wide swing arm and plenty of space for the chain and tire to live without rubbing. I'll double check my pics for a different story.

edit to add pic of sampa's :

Thats why I wanted a picture.

I don't think it should be rubbing either.

That would be a wildly misaligned wheel..

900rider · 10-09-2012, 10:06 AM

I haven't had my rear wheel off in a while, possible to misalign by swapping the spacers by mistake?

Spacer got dropped, is more like it!!
Edit to add: the sprocket bolts would rub on the swingarm with no spacer...

My chain took off a bit of the rear frame twice. Once because the shop (apparently since i hadn't touched it) had left the rear wheel misaligned. Wasn't much but enough for the engine breaking to push the chain to the rear frame. The second time was when my chain was weirdly worn so that the length was ok but it was really slack sideways. I think i mishandled the o-rings or something. Basically those are the only options i can come up with why the chain would rub.

Just rolling along. Grabbed a dirt tag. The TKCs would have been useful for the 2 miles of mud getting the tag, but the Pilot 3's were preferred for the 250 miles of twisties to and from it

Another bow to Mr Barlow and his route selection!

Surely you have found a lighter and cooler running set of cans by now???
The fact you are still running stock exhaust is interesting. It must serve your purpose some how?

I am not worried about the tire, there is plenty of rubber in that area, but I am conserned about the wheel and its position in the swing arm.
When mounted in the correct position, it should not rub the chain guard and the chain, I doubt that it was the KTM engineers intention.

There seems to be a spacer on both sides of the wheel, I will take the wheel of the bike and look more careful.

The chain and sprockets are really worn, I have new parts that will go on the bike this weekend, maybe that will be the end of the chain rubbing the tire.

How do I attach a picture? Link to picture: http://www.sporthoj.com/forum/attach...1&d=1349896548
