If you dont believe me than check out this website: http://www.novarossi.com/eng/motori/ns12s3.htm

How can a motor with a smaller stroke and a smaller bore be bigger.... Just a thought................

You guys are using the palmaris calc wrong .... Punch in the a stroke of 14.02 and a piston bore of 13.79...... It is all legal


I know for a fact that web guys sometimes input the wrong info... I would imagine that the motor is more likely to be legal than not....
i didn't use the palmaris website cal.............anyway it works..........

just check the info on ninja engine website and do the maths.........

stroke>>> 13.78
bore>>>>14.02

capacity = pi*(14.02)²/4 * 13.78


=>capacity = 0.1298 cubic inch............
