Abstract
An engine unit for a motorcycle that efficiently supplies lubricating oil to a clutch mechanism includes a connecting rod connected to a crank shaft, an oil pump, a clutch shaft having a clutch shaft body and a centrifugal type clutch, and a reduction mechanism having a reduction shaft in parallel to the crank shaft. The oil pump supplies lubricating oil to a connection of the crank shaft and the connecting rod. The clutch shaft body is arranged in parallel to the crank shaft. The clutch shaft body is closer to the crank shaft than is the reduction shaft. Lubricating oil supplied to the connection to scatter is led to the clutch shaft.
