Performance Profile & Rider Fit
Best For
Rider Profile
| Best For | Suited to intermediate and experienced riders comfortable managing 800+ lbs of heavyweight cruiser; not a beginner-friendly first bike. |
| Purpose | Classic American highway touring and relaxed cruising, with removable windshield and hard bags for long-haul two-up travel. |
| Rider Fit | Low 26.5in seat, wide bars, forward-relaxed ergonomics and huge 812lb mass; easy to plant at stops but heavy to maneuver at low speed. |
| Character | Big-torque Twin Cam 103 V-twin that lopes down the highway with effortless roll-on, chrome charm and stately, unhurried presence. |
| Not Ideal For | Not for off-road, track days, tight-city darting or riders seeking nimble sporty handling and quick lean-angle cornering. |
