1stly, I am new here. I have had a look through the posts but don't seem to find and info relating to my topic.
My reason for wanting to do this is I am building a super single race bike, Honda 500 XL motor in the MC18 chassis, and it's difficult to find race rubber in the stock 18" rear wheel of the MC18. I have got my hands on the rear end of a MC21 which includes the swingarm, axle, caliper and wheel.
I'm keen to know if this is going to be a straight swap or not. My initial measurement show the MC21 is about 5mm wider the the MC18, but the MC 18 seems to have more than that in excess space. Would it just be a case of swapping spacers etc? Has anybody done this before?
