- Proper size sockets for front (uses a large hex bit, don't try to use the tool in your kit that fits in it) and rear (large socket, again, don't bother with the tool in the kit although you won't break that one, it just won't accomplish anything because it's about 10x too short to get enough torque) plus breaker bar to remove
- Torque wrench to install
- front and rear stands
- a few other hex bits to remove the front axle pinch bolt and rotors (if necessary)
- a rag to cover the front fender if using a triple tree stand in the front
- rear spools recommended for the back
- a friend to help balance the bike while you lift on the rear stand to reduce the chances of dropping it, front will be easy once the back's up so you won't need your friend anymore
- if you play with the front brakes while your rotors are not sitting in the calipers you'll need a thin but strong bit of wood to pry the calipers open again without damaging anything, I know from experience
