Question

Can i put a 1989 ninja 500 motor into my 2003 ninja 250 motorcycle?

Answer 1

Look at it this way  the motorcycles were designed by  people who went  to school for many years and have been designing motorcycles for a long time. They seem to think that it took two motorcycles to fill those sizes. You might not want to do it.

Answer 2

Hm. I'd have to question the strength of the frame. Not meant to hold the weight or the  power.  Maybe they overbuilt it.  Might reinforce the cradle, to make it stay in it's place.
