Rider Profile
| Best For | Best suited to experienced riders who are comfortable managing a long, heavy, radically raked custom cruiser at low speeds. |
| Purpose | Built as a boutique showpiece cruiser for cruising and turning heads rather than for outright performance or long-distance touring. |
| Rider Fit | The low seat height helps at a stop, but the long wheelbase, wide 260mm rear tyre, and aggressive 33-degree rake demand strength and deliberate input for slow maneuvers and U-turns. |
| Character | A rare, hand-built American custom with a big V-twin rumble, chrome billet styling, and one-of-25 exclusivity that rewards riders who want to be seen as much as ride. |
| Not Ideal For | Not for riders seeking sharp cornering ability, off-road capability, or a nimble everyday commuter. |
