I decided to make this since I had a rough time finding this info.
Initial differences:
01-02 uses 320mm front rotors (same as the 99-07 Hayabusa) and a 220mm rear rotor.
03-04 uses 300mm front rotors and a 220mm rear rotor.
05-08 uses 310mm front rotors (same as the 08-09 Hayabusa) and a 220mm rear rotor.
The 05-08 wheels are lighter than 01-04 wheels and they have thinner spokes. I dont have exact weights for the wheels but I held an 06 front wheel in one hand and an 04 front wheel...
