IF you have all the parts you need, it shouldn't take long.
Is the new wheel ready to go? Bearings good, dust seals good?
Are the calipers ready to go? Seals are good, pistons are clean, brake pads are good?
Are the rotors true? If you are replacing pads, prep the rotors!
Do you have new brake lines to install?
Do you need anything to make the vmax wiring plug into the R1 master brake switch?
What are you doing for a speedometer?
Do you have a fender and the hardware needed to install?
Fork Extensions- I would be buying a set of these if you don't have 'em. Even though COO's triple has a 1.5" or 2" drop, you will probably still want extensions. 2" extensions at that.
