  • Straddle Type Vehicle
    Publication number: 20090255489
    Abstract: A motorcycle includes an engine, a radiator that cools a cooling liquid, a first piping that connects the engine to the radiator, and a second piping that connects the engine to the radiator. The second piping, engine, radiator and first piping form a circulating circuit through which cooling liquid circulates. At least one of the first and second pipings is substantially constituted by resin piping. The time required to warm up the engine is thereby reduced.
