View Full Version : Can you put a 1125R frame on a firebolt?

I was wondering, with the larger fuel capacity of the 1125R would people consider putting the frame on a firebolt? I'm thinking that the Engine Mounts would be different, but perhaps that could be handled. any Ideas? Do you Know BPG??

Its not possible, but if larger fuel capacity is what you're after, you can use a frame from a XB12Ss. I think you may have to swap some other things like the swing arm as well.

But the Ss frame does not have the same radical steering geometry then the firebolt

No its not as short, but it's still shorter than the 1125R frame

Well not just for the length of the frame:
SS: Rake (at steering head) 23.1º 23.1º
Fork Angle 21.6º 21.6º

Firebolt: Rake (at steering head) 21.0º 21.0º
Fork Angle 21.0º 21.0º
