Dont know if NSR stuff is same as NC but a rather trick set of fork legs.

Obviously the OD is correct, but I'd imagine it'll be the length that's the main thing. Is there any benefit to fitting NSR forks to a VFR? Do they have better calipers without the need to fit brackets on the NC30 forks. They do look pretty trick though.
