A recreational vehicle includes a seatbelt sensor configured to detect when a seatbelt is in an engaged position or a disengaged position and an engine control module in communication with the seatbelt sensor to automatically limit a maximum speed of the vehicle to a reduced maximum speed limit upon detection of the seatbelt is in the disengaged position.

An engine control device for an engine provided with a supercharger, including a cylinder injection valve and a port injection valve. The device includes an injection controller that controls injections of fuel through the cylinder injection valve and through the port injection valve, on the basis of at least a load on an engine. The injection controller, in a low load operating state, causes the fuel to be injected through the port injection valve; in an intermediate load operating state, causes the fuel to be injected through the cylinder injection valve during an intake stroke, and causes the fuel to be injected through the port injection valve; and in a high load operating state, causes the fuel to be injected through the cylinder injection valve at least during an intake stroke and during a compression stroke.
