Rider Profile
| Best For | This bike suits riders with some prior experience who appreciate a characterful, classic V-twin rather than raw outright performance. |
| Purpose | It's best suited to spirited road riding and weekend backroad touring rather than track days or long-distance highway cruising. |
| Rider Fit | At 180 kg with a modest seat height typical of the era, it's manageable for most physiques and easy to muscle around at low speeds. |
| Character | The air-cooled V2 with a six-speed gearbox gives it a distinctive, torquey and mechanical feel that rewards an engaged, involved riding style. |
| Not Ideal For | It's not the right choice for riders seeking modern power, off-road capability, or comfortable two-up long-distance touring. |
