Rider Profile
| Best For | Best suited to intermediate to advanced off-road riders who are comfortable with tall seat heights, aggressive suspension travel, and a peppy competition-focused engine. |
| Purpose | Built as a pure enduro competition machine for tackling trails, technical terrain, and off-road racing rather than commuting or highway use. |
| Rider Fit | Requires reasonable rider height and fitness given the tall 956mm seat height and light but physically demanding standing-focused riding position. |
| Character | A lightweight, high-revving, race-bred single that rewards aggressive, active riding with sharp handling and strong off-road agility. |
| Not Ideal For | Not a good fit for riders wanting a comfortable daily commuter, a passenger-friendly bike, or long-distance paved touring. |
