well i know its a diff bike but i had my bandit 400 lowered by buying the different dog bones off ebay - they were cheap and they lowered it quite a bit - got a mate to fit em for me and he also slightly lowered the forks to ensure bike was proportioned (im sure that aint the word im looking for hahaha) well enough as in balanced front and back once lowered.
on my cbr400 i just lowered he forks but that means you can dive into corners more sharply mid corner so to speak which some peeps like but you gotta make sure its all balanced front and back when you lower it. THe only other thing it affected on my bandit was the side stand obviously is closer to the ground so it doesnt lean over quite so much so if lowered a lot you may need to sort your side stand too or just be aware when parking up!!
i got fed up with all the lowering milarky and am now the very very happy owner of a harley sportster which fits me like a glove just as she is... wooohooo at last lol
anyhow its all possible to lower just a bit of changing to do and enjoy your lurverly newww bikey x
