| Purpose | Built as a rolling engineering spectacle and torque-monster cruiser, it exists to deliver a jaw-dropping, low-RPM grunt experience and turn heads rather than to be ridden hard or fast. |
| Rider Fit | Riders need real strength and low-speed balance skills to manage its massive weight, huge front wheel, and low-speed maneuvering, though the low 800mm seat height helps with reach to the ground. |
| Character | It has an outlaw, larger-than-life industrial character defined by thunderous low-end torque, a massive V-twin heartbeat, and a slow, deliberate, intimidating presence rather than outright speed. |
| Not Ideal For | This is not for riders wanting agility, cornering finesse, off-road capability, or a conventional day-to-day commuter experience. |
