Go for it!!!!!!!!!!!!!!!!!!
I've made some spacers for a rm125 rear wheel to fit in my RMZ250.
On the K-5 are Yz Öhlins forks. We have made some spacers, new axle, front cliper and more small things to fit works creat.
Look at exel, they have interchangable wheel. Mabey you can steal some idea's!!!
