A vehicle has a frame; a motor connected to the frame; a rear drivetrain connected to the frame; a front drivetrain connected to the frame and having a lockable front differential; a manual override control; and a controller operatively connected to the lockable front differential and to the manual override control. The controller is adapted for controlling the motor to limit a speed of the motor when the front differential is locked and the manual override control is not activated.

A switch assembly for mounting to a handlebar of a vehicle is disclosed. The switch assembly has a main housing mounted to the handlebar. The main housing has a first lateral side, a second lateral side opposite the first lateral side, a rear side, and a front side. The main housing defines a recess. The recess opens in the first lateral side and the rear side. The switch assembly also has one of: a cap selectively received in the recess; and a switch housing selectively received in the recess. The switch housing has a switch mounted thereto. The switch is configured for communicating with a component of the vehicle. The recess is configured for receiving the cap and for receiving the switch housing. A vehicle having a handlebar with the switch assembly mounted thereto is also disclosed.

A controllable differential system for a vehicle includes a differential that may be disengaged or engaged, and may further be locked when engaged. A differential lock switch has three positions for sending commands to an actuator for disengaging or engaging the differential and for sending commands to a controller for unlocking and locking the differential. The vehicle includes a motor, a transmission continuously connected to a rear drivetrain, and the differential mounted in a front drivetrain. The vehicle may be driven in rear-wheel drive mode when the differential is disengaged or in four-wheel drive mode when the differential is engaged. The vehicle may enforce a vehicle speed limitation or an engine speed limitation when the differential is locked while a manual override control is not activated. The vehicle may implement an anti-lock braking system that may be disabled when the differential is locked.

A method for controlling engine braking in a vehicle comprises: determining a position of a throttle operator; determining a speed of the vehicle; and determining an engine braking mode selected. In response to the position of the throttle operator being a fully released position and the selected braking mode being a first engine braking mode: controlling an engine and a position of a throttle valve according to the first engine braking mode for applying a first level of engine braking. In response to the position of the throttle operator being the fully released position and the selected braking mode being the second engine braking mode: controlling the engine and the position of the throttle valve according to the second engine braking mode based at least on the speed of the vehicle for applying a second level of engine braking. A vehicle implementing the method is also disclosed.

A vehicle headlight system has at least one headlight having low, high and off modes. A controller is electrically connected to the at least one headlight and communicates with a switch. The switch has first, second and third positions. The second position is intermediate the first and third positions, and is biased to return to the second position from the third position. The controller controls the at least one headlight to be: in one of the low beam mode and the high beam mode when the switch is in the first position; in another one of the low beam mode and the high beam mode when the switch is in the second position; in the off mode when the switch is in the third position for more than a predetermined amount of time. A method for controlling at least one headlight of a vehicle is also disclosed.
