Honda CB400, just a wee squirt, sure makes getting to and from work a helluva lot easier though!
Also not too bad in the twisty stuff..
Havnt done a lot to it, just k&n filter, cut down a two brothers pipe for a bit more noise - bit of wank more than anything.
MX bars for a bit more leaverage, pazzo shorty brake and clutch leavers, and some more little bling bits.
