I have a 2021klx300r that I am trying to put a set of supermoto wheels on, the only problem is all I can find are wheel packages for the kx250f or the kx450f is there a big difference in the wheels? If the axles are a different diameter can a spacer be used to make up the difference? ( Like a spacer to make the axle 22mm from a 20mm) new to this but would really like to do this without spending a fortune on factory klx300sm wheels. Thanks for the help, Clayton

 

i would think you'd need a set of klx250sf wheels for a direct fit. Look on eBay, you'll find some used or from salvage.

 

Or keep an eye out here. Seems someone wants to sell or trade off a set on occasion. Other option would be to get any KLX250/300 rear wheel and an 09 or later front wheel and lace up a set of 17s to them.
