Bought some wheels(warp9) a while back(yesterday) and since this will be my first time dealing with supermoto I didnt know there was a difference between axle sizes and hole count for rims. The wheels I bought were on a 2001 Yamaha WR426F, and my goal is to put them on a 1997 Honda CR250R. My first question is, since the front rims from my sumo wheels to my dirt wheels have the same spoke count, can I just relace the dirt hub into the sumo wheel? Second question. The rear dirt wheel has 16 spokes, while the sumo wheel has 18. What can I do to fix that issue? Is there a Honda hub that will have 18 spokes that I can buy and relace? or is there some kind of conversion kit? Also does anyone know the axle size for a 1997 Honda CR250R, I can't seem to find it anywhere, not even in the Clymer handbook for my bike. Thanks Guys!
