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. |
