The invention discloses an engine and a motorcycle, the engine is provided with a cooling system, the cooling system comprises a large circulation cooling system and a radiator, the large circulation cooling system comprises a large circulation cooling channel communicated with the radiator, and the large circulation cooling channel is arranged in the engine. The cooling system further comprises a small circulation cooling system, the small circulation cooling system is provided with a small circulation cooling channel communicated with the large circulation cooling channel, and the small circulation cooling channel is arranged in the engine. The large circulation cooling channel is provided with a large circulation liquid inlet communicated with the liquid outlet end of the radiator and a large circulation liquid outlet communicated with the liquid return end of the radiator. The radiator is arranged at the longitudinal front end of the engine, the large circulation liquid inlet faces the radiator, and the large circulation liquid outlet is close to the liquid return end of the radiator. The water pipe layout in the engine cooling system can be optimized, arrangement of water pipes is reduced, meanwhile, the silencer is better arranged, and therefore the whole vehicle is more compact.
