No difference. Maybe heavier steering and not as responsive.

Squeezing wide 140mm radial onto narrow rims causes some nervousness at limit. You'll end up with 5-10mm unused stripe on edges of 140 tyre, so effectively you'll be using only 130mm of it anyway. You'll want to retrofit Ninja 300 4.0" rear wheel in order to make most use of 140 tyre.

Many, many reports of Ninja 400 racers going from 150 to 140 tyre for improved handling. That's because Kawasaki didn't upgrade 400's rear-wheel from Ninja 300's 4.0" width. So 150 tyre just doesn't work on that narrow of rim.
