Rough-water-inspired deep-V hull
Stable and predictable
The “Brain” that integrates and controls all systems to create the best possible ride.
Allows the hull to move independently of the upper deck, isolating rider and passenger from the impact of rough water. 5.5". of travel with manual adjustment under the seat so rider can adjust suspension to different water conditions and total passenger weight.
Stepped, stable & strong. The stepped design reduces drag and keeps you glued to the water.
Touring mode / sport mode
Offers a choice between two throttle responses for different riding styles. Touring mode is the default setting, offering a more progressive acceleration curve for a more confident ride – ideal for cruising and 2-up riding. Sport mode can be easily activated using the Sport button. It provides all acceleration performance for a more aggressive throttle response.
This iTC function automatically determines the most economical power delivery and sets the optimal RPM for greatest fuel economy.
