the popular mod for body is a rr tail swap.
suspension mods can be rear swingarm swap and/or front end swap. or just rebuild front forks with uprated springs and emulators. better set of tires.
engine mods are ignition advancers, airbox mod, removal of emissions control if your bike came with them.
