Abstract
In a V-type engine for a motorcycle in which both banks are arranged in a V-shape in a plane orthogonal to the axis of a crankshaft and the heights of both the banks are different from each other, the heights of the pair of banks are visually recognized to be almost equal to enhance the functional beauty of the engine and improve the marketability. A plurality of fins are aligned in the direction along cylinder axes and are provided on sides of cylinders and on sides of dummy covers for covering at least part of cylinder heads from the sides. Wherein the total number and center line mutual distances of the fins are almost equal in both banks. Lengths between the center lines of the fins closest to a crankshaft of the fins and a cross point of the cylinder axes are set to be almost equal in both the banks.
