A straddle-type vehicle includes a fuel pipe provided on a rear side of an engine, a generator provided on the rear side of the engine and adjacent to the fuel pipe, an outside air introduction duct configured to guide air outside the straddle-type vehicle to the rear side of the engine, and a partition wall provided between the fuel pipe and the generator. The partition wall partitions a region on the rear side of the engine into a generator arrangement region where the generator is provided and a fuel pipe arrangement region where the fuel pipe is provided. The outside air introduction duct includes a first outlet configured to allow the air to flow out to the generator arrangement region.

A front suspension assembly for a vehicle having a connector adapted for connection to a front ground engaging member of the vehicle, a lower swing arm adapted for pivotal connection to a frame of the vehicle about a lower swing axis and being pivotally connected to the connector, an upper swing arm adapted for pivotal connection to the frame about an upper swing axis and being pivotally connected to the connector, the upper swing arm being above the lower swing arm, and a shock absorber assembly having a first end adapted for pivotal connection to the frame above the upper swing axis and a second end pivotally connected to the upper swing arm. The connector is pivotable relative to the lower and upper swing arms about a steering axis. A vehicle having the front suspension assembly is also disclosed.

This measurement device for measuring the angular velocity or acceleration of a two-wheel vehicle, is provided with a main detection unit which detects the three-axis angular velocity or three-axis acceleration, a support unit which can support the main detection unit on the body of the two-wheel vehicle, and a correction unit which cancels the lean of the body to the left and right in the main detection unit.

A vehicle includes a frame, a seat, a storage box, an engine body at least partially overlapping with the seat when seen from above, an intake system component, a fuel system component, an evaporative emission system, a pressure sensor, and at least one of an electric vent valve or an electric suction pump. At least one of the pressure sensor, the vent valve, or the suction pump is supported by at least one of a frame, a storage box, an engine body, an intake system component, or a fuel system component.

A balanced motorcycle powertrain is described. Embodiments of the balanced motorcycle powertrain include components mounted to a frame of a motorcycle such that the powertrain can be evenly balanced about a centerline of the frame. The balanced motorcycle powertrain can include, but is not limited to, a motor, a transmission, a pair of clutches, a clutch shaft, a crank shaft, a pair of superchargers, a pair of chains, a pair of rear sprockets, and a rear wheel. Each of the components can be oriented such that the powertrain is substantially balanced about the centerline of the frame.

A controller and a control method are capable of improving safety by automatic emergency deceleration action while suppressing a motorcycle from falling over. One arrangement also obtains a brake system that includes such a controller. In the controller, the control method, and the brake system, a control mode that causes the motorcycle to take the automatic emergency deceleration action is initiated in response to trigger information generated in accordance with peripheral environment of the motorcycle. In the control mode, automatic emergency deceleration that is deceleration of the motorcycle generated by the automatic emergency deceleration action is controlled in accordance with a lean angle of the motorcycle.

A saddle-riding vehicle includes a radiator in front of an engine of the saddle-riding vehicle and on one lateral side of the vehicle in a vehicle widthwise direction with respect to a center line in the vehicle widthwise direction. The radiator includes: a radiator body that allows coolant of the engine to flow through the radiator body; a radiator fan at a rear face of the radiator body; and a fan cover that covers the radiator fan from a rear of the radiator fan to guide exhaust air from the radiator to the one lateral side in the vehicle widthwise direction.
