Rider Profile
| Best For | Best suited to riders who already have experience handling heavy, low-slung custom cruisers with a big stretched-out wheelbase. |
| Purpose | Built as a bold styling statement and boulevard cruiser rather than a performance or utility machine. |
| Rider Fit | The low 616mm seat height makes it approachable for shorter riders, but the 321kg dry weight demands strength and confidence at low speed and when maneuvering or parking. |
| Character | A rumbling, big-inch V-twin custom with laid-back ergonomics, raked-out front end, and unmistakable American chopper-inspired presence. |
| Not Ideal For | Not a good fit for riders wanting agile cornering, off-road capability, or a sporty, high-rev riding experience. |
