Rider Profile
| Best For | Best suited to riders who already have some experience handling heavy, big-displacement cruisers at low speed. |
| Purpose | Built primarily for relaxed long-distance highway touring and boulevard cruising rather than outright speed or sport riding. |
| Rider Fit | The substantial dry weight of around 328 kg and low seat height make it manageable at rest but demanding to muscle around in tight maneuvers or parking situations. |
| Character | A classic big-twin American tourer with a torque-rich V2 engine, deep exhaust note, and stately, unhurried road manners. |
| Not Ideal For | Not a good fit for riders seeking sharp cornering agility, off-road capability, or quick acceleration. |
