A four-cycle multi-cylinder engine includes a crankcase, a cylinder block, a crankshaft, and a gear-shift input shaft. The crankcase is vertically divided into an upper case and a lower case. The cylinder block is integrated with the crankcase. The crankshaft and the gear-shift input shaft are journaled to a contact surface of the crankcase. The cylinder block is inclined rearward such that an extended line intersects with a cylinder axis line of the cylinder block at an acute angle in an engine side view. The extended line connects respective central axes of the crankshaft and the gear-shift input shaft.

An exhaust control device for engine configures an exhaust system by joining exhaust pipes at a collecting pipe. The exhaust pipes are coupled to a plurality of respective cylinders. At least two types of exhaust valves are configured to perform an exhaust control at different parts in the exhaust system. The exhaust control device for engine includes first exhaust valves, a second exhaust valve, and an actuator. The first exhaust valves are mounted to a plurality of communicating pipes and communicating the predetermined exhaust pipes. The second exhaust valve is mounted to the collecting pipe. The actuator is configured to drive to open and close the second exhaust valve. The first exhaust valves are configured to be driven to open and close corresponding to an actuating region of the second exhaust valve.

A motorcycle is provided with an engine unit having a crankcase and a cylinder assembly protruding diagonally frontward and upward from the crankcase. An air cleaner box has a rearward-descending shape extending from the upper side to the rear side of the cylinder assembly as seen in a side view to form a vertically elongating box shape. The air cleaner box is disposed between left and right frames of a chassis, and both side surfaces of the air cleaner box are separated from the chassis. The air cleaner box has a frontward-narrowing and rearward-narrowing width as seen in a top view. As a result, it is possible to obtain a sufficient box capacity and facilitate a compact design. In addition, it is possible to smoothly flow an air stream in the lateral sides of the air cleaner box.
