You will need the GSXR wheel, guard, discs and calipers.
Unfortunately the K5 1000 went to a different front end so they are not interchangeable like the 01-04 1000/750/600 models.
The Hayabusa run the same wheel as the TL which is different to the GSXRs.
So to save a lot of dramas it will be better to use K5 1000 everything.
I just did the swap on my '03 B12 and after I got the parts it was a fairly simple job.
You will also need to get a spacer machined up for the top clamp as the Bandit stem is a smaller diameter than the GSXR one at the top where the two meet.
I got one of these ABM top clamps so I could avoid clip-ons.
The forks are shorter but if you keep the ride height at the rear as close to stock as possible you shouldn't have any problems with stability or clearance.
