Abstract
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.

1-20. (canceled)
A vehicle for traversing the ground, comprising:
- a plurality of ground engaging mechanisms;
- a plurality of vehicle systems supported by the plurality of ground engaging mechanisms, the plurality of vehicle systems including
- a plurality of suspensions operatively coupling the plurality of ground engaging mechanisms to the chassis;
- and
- a drive train including an engine, the engine being operatively coupled to at least a portion of the plurality of ground engaging mechanisms to drive the portion of the plurality of ground engaging mechanisms;
- a chassis supported by the plurality of ground engaging mechanisms;
- a seat supported by the plurality of ground engaging mechanisms, the seat having a forwardmost extent, the plurality of ground engaging mechanisms having a first portion positioned forward of the forwardmost extent of the seat and a second portion positioned rearward of the forwardmost extent of the seat;
- a steering input positioned in front of the seat, the steering input operatively coupled to the first portion of the plurality of ground engaging mechanisms;
- a plurality of sensors supported by the plurality of ground engaging mechanisms, the plurality of sensors including a first suspension sensor operatively coupled to a first suspension of the plurality of suspensions to monitor a characteristic of the first suspension;
- and
- a controller operatively coupled to the plurality of sensors, the controller based on at least one of the plurality of sensors being configured to:
- determine if the vehicle is airborne;
- and
- adjust a performance characteristic of at least one of the plurality of vehicle systems based on the vehicle being airborne.
11 more elements
A method of adjusting vehicle performance, comprising the steps of:
- providing a vehicle configured to be driven relative to the ground by operatively coupling an engine to at least one ground engaging mechanism, the vehicle including a plurality of vehicle systems including at least one suspension and a drive train, the at least one ground engaging mechanism being movably coupled to a chassis of the vehicle through the at least one suspension;
- monitoring a suspension sensor of the at least one suspension of the vehicle;
- determining the vehicle is airborne;
- and
- based on determining the vehicle is airborne, adjusting a performance characteristic of a first vehicle system.
2 more elements
A method of controlling performance of a vehicle, the method comprising the steps of:
- receiving a drive mode selection through a user interface supported by the vehicle;
- adjusting at least one of a plurality of vehicle systems supported by a plurality of ground engaging mechanisms based on the received drive mode selection, the plurality of vehicle systems including a plurality of suspensions operatively coupling the plurality of ground engaging mechanisms to a chassis;
- and a drive train including an engine, the engine being operatively coupled to at least a portion of the plurality of ground engaging mechanisms to drive the portion of the plurality of ground engaging mechanisms;
- determining if the vehicle is airborne wherein the plurality of ground engaging mechanisms lose contact with the ground;
- and
- adjusting the at least one of the plurality of vehicle systems based on the vehicle being airborne.
