I don't want to get into a tire brand discussion, just a size question.
The tires I run on my 525 are 120/100-18. The next size is the 140/80-18. I was thinking if I dropped down to the 120 I might just be able to keep the lowering link installed and not hit the tank.
Another thought- I haven't noticed any posts or threads about drilling the drain holes in the 690 swing arm. Isn't this an issue with them as with the rest of the KTM line?
I ran the Kenda trakmaster II on the rear in a 120/100-18 for a little over 1000 miles without any issue. The tire worked fine, no rim issues, no abnormal wear issues and I was on dirt and pavement. In the woods the narrower tired hooked up almost as well as a trials tire...it was very impressive. I also have run a trials tire on the rear with no issue.
