will a ninja 300 engine bolt straight into a 250 ninja?

From what I was able to find, it doesn't seem as simple as just bolting it in, but it doesn't appear to be too hard to swap them either.

Personally, I don't think it would be worth your time, though.

Have I done it - Nope.
Do I think its a bolt in - Yes!

Second Pic: Ninja 250 - doing motor swap. Rotten Ronnie's bike.

The front frame mounts are stamped steel and removable.
When I Swapped that motor on Jason - Rotten ronnie's bike - his mounts were twisted.

The donor bike's mounts were perfect, so even if the front mounts need some work - it would be easy job to do that.
