Rider Profile
| Best For | This machine suits a confident, experienced rider who is comfortable managing a long, heavy, low-slung custom cruiser with a wide rear tyre and stretched wheelbase. |
| Purpose | Built as a bold styling statement and boulevard cruiser, it's meant for relaxed, image-driven riding rather than outright performance or sport handling. |
| Rider Fit | The low 616 mm seat height makes it approachable for shorter riders, but the 318 kg dry weight and long 2083 mm wheelbase demand strength and care at low speeds and when maneuvering. |
| Character | It has the soulful, torque-heavy pulse typical of a big-inch 45-degree V-twin, delivering laid-back, deliberate power rather than high-revving excitement. |
| Not Ideal For | This is not the bike for riders seeking agile cornering, off-road capability, or a light, flickable ride through tight city traffic. |
