I can't believe you guys, you're misisng the most obvious improvements to a bike's performance:
Anodised footpegs
Tinted screen
illegal can with NO jetting changes
Tiny numberplate (helps the police to stop you and find your can is illegal)
stick-on tank protector
Leather suit with knee sliders

I hold visions of your bikes in my mind's eye as my tuning inspiration GC - honest!!
