I recently had my rear blow out. replaced it with a shock from an 08 z400. had to grind alittle off the insides of the lower mount to get to fit but very little. makes the bike sit bout an inch higher in rear and is a little stiff but seems to work fine. had to adjust the preload really soft but rides good. im bout 175lbs or so, so would probably be perfect for someone alittle heavier
