You dont think the electronics will have any problem with the different wheel speeds being input into the ECU with a 18/19 combo?I'm sticking with the stock rear - at least for now. I don't see any reason to change it yet.
Years ago, I would often change KTM990 rears from 18 to 17 because there were so many more tire choices available. These days there are plenty of wide 18s to choose from.
OK I like your thinking.Hey SkipD. I think the electronics will still work fine with the diameter difference. The only way to know is to build the wheel and go ride it. If the electronics do have a problem I will make a new front ABS reluctor ring with the appropriate number of slots in it to make up for the diameter difference.
The rim is a Sun 2.75 x 19 laced up with Buchanan's stainless steel spokes. I've mounted up a Motoz Adventure 110/80-19.
Edit: You don't lose any cornering clearance because the 110/80 tire is a lot wider so it holds the bike higher when leaned way over. It might even gain a little bit.
Also, even though the rim diameter is a 2" difference the overall diameter of the 19" tire is only 1" smaller than a 21.
I haven't test fit it because my forks are still out to Cogent Dynamics but I did measure before getting started on the wheel project. I should have about 1/4" clearance on either side between the tire and inner surface of the fender.OK I like your thinking.
The Motoz is quite wide at the outer knobs have you tried it for clearance on the front guard or have you gone for the high front guard.
I was thinking of a fat street tire for the 19 and keeping the 21 setup for offroad.
Camel ADV have tanks plus a high fender kit, they also do a right side peg support kit that I think is a must have.I haven't test fit it because my forks are still out to Cogent Dynamics but I did measure before getting started on the wheel project.

I'd like to do a high fender set up but haven't done any research in that direction yet. Who has a kit? Is there a DIY setup?
I converted my KTM990 after watching a buddy tear the front fender and ABS sensor off of his in the mud :surprise:
Couchy have you had a chance to run the 19 yet, any issues with ABS or TC because of the smaller dia (I am thinking not because when they Dino them front wheel is fixed) What tire and rim size are you looking at.Getting my spare wheels done with a 19” front in next few weeks, will report back. I’ve raced bikes for 10 years and done 300+ Trackdays, the AT is my only bike these days but I’ll still go to a few Trackdays to see mates so I’ll drop the 19” then with a slightly wider tyre, still won’t set the world alight but I’m sure it’ll be a good laugh and take a few sportsbike scalps ?
