Hi everyone. It's my first post but I'm following the forum since more than a year I'm working on a SE from 83 and I want to change the original alloy wheels. Initially I was looking from different swingarms that would fit, but I would loose the round look so I decided to stick with the original. Finding xs spoken wheels here where I leave is difficult, but cross/motard are easy to come by. I've been looking around quite a lot, but could not find any info about fitting supermoto/cross wheels on the xs (cr250/ktm400). I have found a couple of 18" supermoto rims+tyres from a ktm, that have the same axle size(17mm in the front and 20mm in the back). My may concerns are about the rear wheel, mainly the sprocket alignment, size of the rotor and possibly the rim being too large? What should I check when buying? Anyone has experience with it?
