Maybe go on a strict diet to lose a few pounds? [img]i/expressions/face-icon-small-wink.gif[/img] [img]i/expressions/face-icon-small-smile.gif[/img]

 

you can change the standar exaust by an HMF, they say it will save 7 lbs compared with stock and you will get a nice power boost.
also you can replace the front grab bar with the gytr aluminium one. I don't know how much it will save you but must be a cuple of pounds. with both you can save about 10 lbs, not too much, but better than nothing.
