What are the minimum CC that require a motorcycle license in Kansas?

From K.S.A. 8-126. Definitions; located at http://www.ksrevenue.org/taxincent-ksa8126.htm

"(aa) "Motorized bicycle" means every device having two tandem wheels or three wheels, which may be propelled by either human power or helper motor, or by both, and which has:

(1) A motor which produces not more than 3.5 brake horsepower;

(2) a cylinder capacity of not more than 130 cubic centimeters;

(3) an automatic transmission; and

(4) the capability of a maximum design speed of no more than 30 miles per hour."

A two wheeled motorized vehicle must be less than all four of these requirements to not be considered a motorcycle.
