I think it'll ALMOST fit, meaning basically no.
I thought of taking the 400 pound Seca 550 and adding the 1100 engine, but that won't work without major frame welding and stretching.
You need to measure the 2 engines.
You would need to do NASCAR quality tube welding for strength.
Everything needs to be "square" and "true"
The swingarm is all wrong.

But you'd end up with a serious HOSS of a bike !!
Just brush up on your German a bit and build this. . .

yeah that 1100 pocket bike is sic!! that is a little crazier than what i want, but not to far off. I have a ninja 600 that i parted out. so i an going to change out the whole front end: forks brakes wheel etc. but then my wheels wont match and i still have a rear drum brake, i found an fj motor for cheap. i was going to try and mod my chassis to accept it and a new swingarm this winter. then i could run rear disc brakes and chain so I could change my gearing. and it would be hella fast. that is the best part

 

Riding position looks very comfortable :lol:

 

That's one way to cut the bikes weight down a bit.
