I loved it on my 99SV650s I slacked off both cables at the handlebar all the way to full slack... then popped it on with little dificulty... it's a b!tch if you try to half-a$$ it and don't slack both cables up as much as you can..
with the gen-2 bikes... I hear it can be a little more tricky... some say you have to modify the side of it like shown on the canyonchaser site

But I have also heard from some gen2 riders that you don't need to cut anything....
It may have something to do with how far the cables have stretched from use already.... or how they slacked off the cables...
all I can say is it was the best $8 I spent on my old 99 sv650s.... I got a full throttle twist without having to reposition my hand or use excessive arm movement to get full throttle
Oh you can get just the throttle tube and fit your own grip.... OR make it easy and get the part with the grip already attached..... AND if you are anal go ahead and get the left grip to match while you're at it... they are cheap even when bought at the yammy dealer
