Powered by the BMW Motorrad K1300 engine, the Quadski XL is capable of attaining speeds of 45 mph on both land and water. The performance and comfort of the ride are the result of a lightweight composite hull, wide track and low center of gravity, which gives the Quadski XL stability on land and water. The most advanced piece of Gibbs engineering is the suspension. It gives a superb ride and handling on land and retracts when on the water. The complete transition takes under five seconds, at the push of a button. Incorporating Gibbs High Speed Amphibian technology, the Quadski XL hull provides a stable planing surface and lateral stability for responsive handling on water. The proprietary Gibbs jet drive is lighter and more compact than traditional marine industry water jets and provides high levels of thrust and maneuverability on water, propelling the Quadski XL to planing speed in seconds.
