Just wanted to post this info since i seem to lose it every time my computer crashes. This is from Steve Scott's web page and was the way he mounted CBR600 F2 wheels on his VF-500. I haven't done the swap yet to confirm his measurements, but he was racing with this set up... The following procedure was lifted from Steve Scott's site...which may or may not still exist Here's what you do to fit CBR600F2 wheels onto a VF500F Front: Remove front wheel bearings and replace with 6302V Machine exactly 6mm from every brake rotor mounting boss on both sides of the wheel. Machine a spacer 2.5 mm thick x 15mm id x 23mm od (right side) Machine a spacer 30.0 mm thick x 15mm id x 23mm od (left side) If you don't already have the small rotor monting bolts for the F2 rotors, go buy some. Bolt it up. Rear: Remove rear wheel bearings and replace with 6303RS Machine a spacer 5 mm thick x 17mm id x 30mm od (left side) Machine a spacer 8 mm thick x 17mm id x 30mm od (right outboard side) Machine a spacer 10 mm thick x 17mm id x 30mm od (right inboard side) Here's where you get to the point of no return... Take your VF500 cush-drive and chuck it into a lathe...remove sprocket, seal, circlip, and studs. Machine the seal pocket off, (10mm off the face where the seal was). Now you have a beautifully machined surface that is flush with the outer surface of your bearing. Machine the Sprocket mounting surface another 10mm deeper. keep the diameter consistent all the way. Shorten all the sprocket studs10mm There is no machining of the rear wheel. You use the F2 rear rotor, a 600 Hurricane caliper hanger with the VF500 caliper. You will have to fabricate a 6" brake-stay arm to attach to the hole in the top of the swingarm on the right side. So, from left to right, it's swingarm, chain adjuster, 5mm spacer, vf500 cush-drive, 4.5" wide wheel, 10mm spacer, caliper hanger, 8mm spacer, chain adjuster, swingarm. Bolt it up.
