Performance Profile & Rider Fit
Best For
Rider Profile
| Best For | Best suited to riders who already have experience handling a heavy, long-wheelbase machine at low speeds and in traffic. |
| Purpose | Built primarily for long-distance highway touring with a batwing-style fairing for wind protection and all-day comfort. |
| Rider Fit | The low seat height helps shorter riders, but the substantial wet weight of over 370 kg demands good strength and confidence when maneuvering at a standstill or during slow parking lot moves. |
| Character | A cruiser-touring character defined by relaxed torque delivery, a deep exhaust note, and stable, unhurried highway manners rather than outright speed or sharp handling. |
| Not Ideal For | Not a good fit for riders seeking agile cornering, off-road capability, or quick acceleration for sport riding. |
