(54) V-type internal combustion engine for motorcycle


(57) Object: To provide a V-type internal combustion engine, which is capable of mounting lifters for chain tensioners on a rear wall of a rear bank without any interference with a mission case portion, while eliminating the necessity of setting a rearward tilt angle at a particularly small value.
Solving Means: A primary transmission unit 54 and a rear timing transmission unit 462 are connected to both ends of a crank shaft 15; and a side wall 95a, on the rear timing transmission unit 462 side, of a mission case portion 95 is offset on the primary transmission unit 54 side from the rear timing transmission unit 462. With this configuration, it is possible to easily mount the lifters 492 for chain tensioners on a rear wall of the rear bank 42 without interference with the mission case portion 95.
