The cockpit features an Ergolock two-piece racing seat engineered for stability and control during aggressive riding, paired with a low, rider-centered position. A large swim platform with LinQ attachment points sits aft for boarding and towing operations. The helm includes BRP Premium Audio and iBR technology for enhanced handling and braking.
