I haven't done a lot to it but heres a list.
Carbon fibre Cans, Ape CCT's, Mild Race Cams, K&N Filter, Pig Spotter Mirrors, CRG Mirror & Custom Bar end, Tank gaurd, Drilled rear pegs & sets, Visior Change, Spike visior Bolts, Upgraded Front springs, Modified tail piece.
I'm thinking of putting nice spikie Motorcross pegs on and changing the indicators to slim leds or flush mounts. Also, 30mm Tail raise kit and a belly pan of some sort... an other idea's?
