Rider Profile
| Best For | This is a big, heavy classic UJM best suited to riders with some experience handling substantial machines at low speed. |
| Purpose | Built as a shaft-driven sport-tourer of its era, it favors sustained highway cruising and long straight-road pulls over tight technical work. |
| Rider Fit | At nearly 270kg wet with a tall, wide stance, it demands decent strength and confidence for slow maneuvers, parking, and U-turns. |
| Character | A torque-rich, air-cooled inline-four with shaft drive gives a smooth, low-maintenance, unhurried muscular character rather than a razor-sharp one. |
| Not Ideal For | Not for riders seeking nimble flickability, off-road capability, or a lightweight commuter for tight urban lane-splitting. |
