yup
That GT frame would prolly work. Or that type of V frame set-up, the middle of the bike has to be open. What I'm wondering is how much travel or "bob" you have to allow for drive chain clearance and proper functioning. As in, if you get too much frame flex that would cause the chain to fly off or mess up your front sprocket or engine performance. I guess you'd have to mount one and see what happens. Prolly have to strenghten the engine mounts to start with, or rig it to flex slightly.
