Rider Profile

Best For	Best suited to intermediate to expert off-road riders who are comfortable with a tall, light, aggressive cross-country race bike.
Purpose	Built for closed-course cross-country and enduro-style off-road riding rather than street use or commuting.
Rider Fit	The tall 37.6 in seat height and minimal weight-carrying comfort favor taller, fit riders confident standing on the pegs for extended periods.
Character	A high-revving, race-derived thumper that rewards an aggressive, momentum-focused riding style with sharp handling and light overall mass.
Not Ideal For	Not a good fit for new riders, passengers, highway commuting, or anyone wanting plush comfort and long-range touring capability.
