Rider Profile
| Best For | This machine is best suited to confident, experienced riders who are comfortable managing a massive, torque-heavy V8 at low speed. |
| Purpose | It exists primarily as a straight-line spectacle and show-stopping cruiser, built for thunderous acceleration and attention rather than nimble riding. |
| Rider Fit | The huge dry weight, long wheelbase, and low ground clearance demand strong, deliberate low-speed handling skills and physical confidence when maneuvering it. |
| Character | It has an outrageous, brash personality defined by raw V8 torque, automotive-derived engineering, and unapologetic size and presence. |
| Not Ideal For | It is not for riders seeking agile cornering, off-road capability, or a lightweight, easy-to-manage everyday bike. |
