Abstract: A vehicle includes a restrictor that prevents movement of a brake controlling operation transmission member and is provided at an upper portion of at least one of an upper cross portion, a right side portion, and a left side portion. The brake controlling operation transmission member includes a leaning-associated deforming portion that is located between a brake controller and the restrictor to deform in response to the leaning of a body frame and a wheel-turning-associated deforming portion at least a portion of which is located between the leaning-associated deforming portion and a brake device to deform in response to the turning of a right front wheel and a left front wheel.

Abstract: A left front fender includes a left upper wall portion, a left side wall portion, and a left guide portion. The left upper wall portion defines a left upper inner surface facing a portion of an upper surface of a left front wheel. The left side wall portion extends downward from the left upper inner surface to define a left side inner surface facing a left side surface of the left front wheel. The left guide portion defines a left guide surface extending rightward from the left side inner surface toward the left side surface of the left front wheel.

Abstract: A hull for a planing type watercraft has a rear portion that includes one or more steppers and a step plate fixed to the hull rearward of the first stepper so as to create a gap between a leading end of the step plate and the corresponding stepper. The step plate may additionally include longitudinally extending channels. The gap may further include apertures to supply air to the gap.

Abstract: An integrated control for a machine such as an engine installed in a vehicle or vessel is conducted by the steps of: determining the characteristics of a user and/or using conditions; and changing characteristics of a control unit of a machine in accordance with the determined characteristics. Normally, the control unit includes: a reflection hierarchy for outputting a base value; a learning hierarchy for learning and operation; and an evolutionary-adaptation hierarchy for selecting the most adaptable module. The machine is “trained” to suit the characteristics of the user and/or the using conditions.

Abstract: A jet propulsion system for watercraft employs twin impellers contained within a common housing assembly. The housing assembly defines an intake duct that delivers water from a single water inlet opening to impellers supported within the housing. The inlet opining can be positioned centrally on the watercraft to avoid drawing air in during abrupt maneuvering. A dividing wall extends from a location forward of the impellers into the water inlet duct to divide the flow of water well upstream of the impellers. The dividing wall is configured to reduce cross-effects caused of the counter-rotating impellers in the water flow upstream of the impellers without requiring any substantial change in direction of the water flow from the water inlet opening to the impellers.
