The 550 XP and 850 XP models feature standard hydraulic disc brakes, while the 850 XP EPS benefits from Electronic Power Steering (EPS) for improved handling and reduced rider fatigue.

The chassis is designed with a high ground clearance of 11.5 inches, and the durable construction supports a payload capacity of 275 pounds on the front and rear racks combined.
