don't get me wrong i'm a cage and bar builder but i respect all other cage and metal workers powers has some pretty good designs.i recently had a customer bring a powers 12 bar over for me to install on his r1''now they might have just sent him the wrong one cuz he got it from gixxergirl.com but if this is the right bar it does not fit right at all it has only 2 atatchment points that are a clamp design if i was to cut the hell out of his bike it could work but as soon as he sets it on the bar a little hard it will colapse foward which could be fixed ''if anyone talkes to them tell them to make a bracket that goes in the end of the subframe of the r1 and if this is a problem with any other bike do the same that way when you set it down harder than you normally would you won't have to fix it every time ......just my opinion hope i don't offend ..thanks brian/nw stuntbike
