A bold, radical custom statement built around a polished S&S V-twin, rigid chassis, and an oversized rear tyre, prioritizing style and attitude over handling.
Not ideal for
This is not the bike for riders wanting agile cornering, long-distance comfort, passenger accommodation, or any kind of off-road capability.
