I was on the Marchesini website and they have an MS Excel spreadsheet showing the fitments available, and for Honda the CRF450, CR250, XR400&650R are all available with the 5.0 rear rim.
Anyway, I measured the swingarm last night and it is almost 7-1/2 inches wide.
The rim will definitely fit, but it will be interesting to see how the offsets work out.
With a centered 5.0 inch rim, there is about 1-1/4 inch clearance each side, the chain takes up maybe 7/8 inch of width, so that leaves 1/2 inch for tire clearance, say a little more that 6.0 inch for tire width.
Now a 160x17 tire is 160mm wide = 6.3 inch. That sounds as if it won't fit! :headscrat
BUT, it seems the actual tire width varies from the stated width, check out this site for instance:
Of course that depends on the tire brand so it remains to be seen which tire I will get for the rear, cause offset is also part of the equation.
A little more can be had if the right spacer is shaved a bit and the left spacer is customed to a wider width, but that depends on the Marchesini hub offset doesn't it?
Hopefully some Junkie out there will put ruler to tire so that once the rims come and I know the offsets, I can get the tire and slip it on with no problems.
Whelp, I was given an estimated wait of 3-6 weeks for the wheels, so thats plenty of time to think about it...
Nice choice Keith :thumbup: . Hopefully you wont have any clearance issues with it. I hate when I see the lip of the rear supermoto Marchesini all chewed up from the chain :headshake . Hey Dan, I bet you are getting the new radial Magura brake setup aren't you :Funny:
