i have done the complete swap,saved 6 + lbs & gained a solid tenth in the 1\8. it is way worth the mod for the cost.

What all did you need for the mod and where can you get it?

I just put a R1 wheel on the back of my 08 busa-You need to mill .120 off the rear caliper hanger, or you could make a thicker spacer to go between the caliper hanger and rear wheel.

depending on your swingarm make,chain alignment offset may vary from swingarm to swingarm.

If you do not mill the caliper hanger- the (gen 2 busa) caliper and the R1 rotor will not be properly aligned, at first I was going to shave some off the right side wheel spacer.....but the spacer is already flush with the dust seal. My rear axle would not go thru the wheel when I first tried because the caliper hanger was so out of alignment.

use a R-1 CALIPER& HANGER W/PROPER SPACING AS THIS COMBO RADIALLY WILL BE THE CORRECT MEASUREMENT.NOT TO MENTION THE R-1 brake assy is much lighter than the 2nd gen busa & has less drag on the disc.with the R-1 hanger flush to the rear rim spacer the caliper will line up axially,then make a spacer for between the hanger & swing arm,your done.

for those of you that are installing the r1 rear caliper and hanger, i thought i would share my setup. it was simple and perfect install on my bike. of course remember as already stated, there are differences between swingarms.....i used the original busa rear axle with the oem adjuster blocks on the outside of the swingarm, i used the r1 spacers on the inside of the swingarm and the r1 brake hanger and caliper so therefore the hanger is properly spaced between the rotor, now i used the right side r1 adjuster block as a space filler on the inside of the swingarm between the hanger and the swingarm... this worked perfect in my swingarm with absolute no machining or grinding....

the only aftermarket thing i had to do was drill and tap to hole in the hanger and installed to stainless steel socket head bolts, then i shrinkwrapped them for a rubber bumper. this will rest on top the swingarm and keep the brake assembly from spinning around when you hit the brake.... of course there is other option of how to do this im just sharing what i did and i have less than 5 bucks in it and a little time.....
