acerbis guards suck, get some cycra's if you want any real crash protection.
here's mine with derlin supermoto bar sliders on the ends...
the acerbis guards on my drz couldn't even take an impact without getting all twisted out of place exposing my had to big nasty rocks. i've drop my tiger at low speeds about 4 times now with these guards in mud, dirt/gravel, and pavement. so far no damage to the bike or my hands.
on mine i did chop my lever ball things off, but i regret that, i think they could be make to fit maybe grinding off half of the balls. (sounds painful tho).
anyway that's my opinion. i will never buy another acerbis handguard.
