WATER-COOLED V-TYPE ENGINE, AND MOTORCYCLE INCLUDING SAME

摘要

A water-cooled V-type engine includes a first coolant passage for supplying a liquid coolant discharged from a water pump disposed proximate a first cylinder, to a water jacket of the first cylinder. The engine also includes a second coolant passage which is branched off from the first coolant passage, and which is provided for supplying coolant to a water jacket of a second cylinder. The engine design allows for a shortened coolant hose. The water pump may include an integral fluid conduit including a branching portion where said second coolant supply passage is branched from said first coolant supply passage, and a restricted portion proximate the branching portion. A motorcycle including a vehicle body frame is also described, where the water-cooled V-type engine is operatively attached to the vehicle body frame.
