Abstract
A horizontally-opposed type engine for a motorcycle, in which a pair of left and right cylinder heads are connected to a pair of left and right cylinder blocks in such a manner that combustion chambers are formed between each of the cylinder blocks containing a plurality of cylinder bores disposed in parallel with the axial lines thereof extending substantially in the horizontal direction and pistons slidably fitted in the cylinder bores; a crank shaft is disposed in such a manner as to be perpendicular to the axial lines of the cylinder bores; and the engine is mounted on the motorcycle with the axial line of the crank shaft extending in the longitudinal direction, wherein the restriction to the bank angle of the motorcycle given by the exhaust pipes is made small and thereby the bank angle is easily ensured. A plurality of exhaust passages, for introducing exhaust gas from the combustion chambers, are provided in each of the cylinder heads in such a manner as to be tilted toward the central side of the motorcycle in the width direction and to be opened downwardly.
