Rider Profile
| Best For | This is a machine best suited to experienced riders who are comfortable handling a long, heavy, custom-styled chopper-style cruiser with a stretched wheelbase and steep 33-degree rake. |
| Purpose | Built as a bold American custom cruiser, it's meant for making a statement on boulevards and at bike nights rather than for outright performance or long-distance touring efficiency. |
| Rider Fit | The low 610mm seat height makes it accessible for shorter riders at a stop, but the near-300kg dry weight and extended front end demand strength and confidence at low speeds and when maneuvering. |
| Character | Torque-rich 45-degree V-twin with a big-inch feel, chrome-heavy custom styling, an aggressive raked-out stance, and a boutique feel courtesy of the Baker overdrive transmission and premium Marzocchi suspension. |
| Not Ideal For | This is not the right choice for riders seeking agile cornering, off-road capability, or a lightweight commuter, as its stretched geometry and heavy mass make tight, technical riding cumbersome. |
