Rider Profile
| Best For | Best suited to riders who already have experience handling heavy, long, low-slung cruisers, especially given the wide 240mm rear tire's effect on steering. |
| Purpose | Built for boulevard cruising and making a visual statement with drag-style styling rather than for outright speed or distance touring. |
| Rider Fit | The very low 665mm seat height suits shorter riders, but the substantial 305kg wet weight demands confidence and strength at low speeds and when maneuvering or parking. |
| Character | A muscular, low-slung factory custom with strong torque off the line, deep exhaust presence, and drag-bike attitude rather than outright top-end performance. |
| Not Ideal For | Not a good fit for riders seeking agile cornering, off-road capability, long-distance touring comfort, or a passenger-friendly setup. |
