I have for sale a set of supermoto 17" wheels for a cr85. Excel rims, Buchanan spokes. Stock hubs. Have Sava supersoft tires with lots of life on them mounted. No sprocket or rotors. Sold the cr85 in dirt configuration. Willing to ship. Located in Winston Salem NC. $400
I'm still learning about dirt bikes and their wheels, but I think you're correct. I could change the hone and re spoke it to fit my bike. I'll think and get back to you. Would you perhaps want to sell one ?
I had this on a big wheel version with the longer swing arm. I am not sure if people are able to squeeze the 17" wheels in on a short swingarm. It probably depends on the tire.
Rear hubs are different from a 150R to a CR85. 17's will fit a standard swingarm on both but very tight and gearing becomes a headache trying to adjust the chain. Some mill out a little of the axle block to allow the axle to slide back a little more.
