A cylinder head for a motorcycle engine in which the cylinder head includes an intake side including an intake passage and an intake valve movably disposed within the intake passage, and an exhaust side including an exhaust passage and an exhaust valve movably disposed within the exhaust passage, the exhaust side being positioned remote from the intake side. A cooling liquid inlet port and a cooling liquid discharge port are located on the intake side. A cooling liquid passage runs through the cylinder head to reduce an operating temperature of the cylinder head.

Cylinder head cooling system

A cylinder head for a motorcycle engine, which has a pair of cylinders arranged in a 'V' configuration such that the cylinders converge toward a crankshaft axis and such that a space is defined between the cylinders at an upper extent of each of the cylinders. The cylinder head includes a base configured to be coupled to one of the cylinders, an intake side including an intake passage and an intake valve movable disposed within the intake passage, the intake side being positioned adjacent the space, and an exhaust side including an exhaust passage and an exhaust valve movable disposed within the exhaust passage, the exhaust side being positioned remote from the space. A cooling liquid inlet port and a cooling liquid discharge port are located on the intake side. A cooling liquid passage runs through the cylinder head to reduce an operating temperature of the cylinder head.
