I have a 09 FE570 and am thinking about getting a set of SM wheels for it. What year and model ktm wheels will bolt right up? How wide of a rear wheel is recommended? Thanks, Mark
03 onwards. up to 02 they had 20mm front axle (rears will still fit) 03 onwards they stepped it up to 26mm-which is the same as your bike. You can get a kit from KTM to fit 20mm axle to your forks as well. 5'' rear rim would be the go, and is also the most popular size for motards.
On my 09 I actually have a 20mm CR450X hub with some custom spacers! all fits good though, well after a bit of fiddling . I run a 3.5" front rim, and a 5" rear (120 n 150 tyres). You will have to cut your fork protectors as the tyres will rub, I just let the tyres cut them and then cleaned it up after with a dremel after the first ride. 150 is a perfect fit, a 160 rear tyre would be a hassle.
