Correct me if im wrong but I think in Europe motorcycle licenses are more strict. When your 17-21 you are restricted to so much horse power. Cant remember the exact amount. So the 125 applies to the young crowed that arn't allowed to buy that turbo busa for there first bike.
I was searching around for exhausts and came across this Leo Vince Exhaust - Leo Vince Racing Slip-On Exhaust Evo II Yamaha FZ6R - Indysuperbikes
Now I know this couldnt be for a FZ6R..Right?
