Performance Profile & Rider Fit
Best For
Rider Profile
| Best For | Suited to riders who have at least some experience handling a heavy, low-slung cruiser with limited ground clearance and cornering lean angle. |
| Purpose | Built for relaxed, torque-driven boulevard cruising and stylish around-town riding rather than outright speed or long-distance touring. |
| Rider Fit | The low 648mm seat height makes it approachable for shorter riders, but the near 304kg wet weight demands confident low-speed control and upper-body strength at a stop. |
| Character | A classic air-cooled V-twin custom with a stripped-down, blacked-out bobber look, deep torque delivery, and a laid-back, rumbling character over outright performance. |
| Not Ideal For | Not a good fit for riders wanting sharp cornering ability, off-road capability, or a bike optimized for long highway touring comfort. |
