Now it's easier to adapt the power delivery to any scenario, inluding the use of the on-command 3-way differential lock which helps the rider get a better grip on slippery terrain or steep slopes.
This quad retains the impressive racking capacity and can tow qute heavy loads, being a dependable partner in completing the toughest tasks and being a fun machine for weekend trail fun, too. The built-in winch mounts make installing this valuable upgrade easy and quick and you'll be up an running in no time. Add in long-travel independent suspensions and engine braking and there you have it, Mr. Quad Versatility.
