That really depends on how low you put it. I lowered mine an inch so I could touch down with more than a tippy toe. I actually had trouble backing out of or into parking spaces. The 1" lowering I did has had little effect on the handling. I am sure there is some but nothing like those streched busa's or those POS chopper/hardley's. Don't go that far pleeeeease..... I needed it lowered to give me better odds at not dropping it. I like it and am used to it know (I haven't grown any more) so it will stay lowered.Z_Fanatic said:More like disadvantage, supposedly it keeps wheelies to a minimum and delivers power efficiently to the rear wheel if the swing arm is also stretched. But it seriously handicaps sportbike's handling to more like stretched choppers and HD.
