Rider Profile
| Best For | Great for riders who want touring luxury without balancing a two-wheeler; its trike layout suits returning, aging, or mobility-limited riders, though its size still demands respect. |
| Purpose | Built for long-haul two-up touring in maximum comfort, hauling gear in its trunk and top box across highways and open roads. |
| Rider Fit | Massive 561kg three-wheeler with a low 688mm seat, wide stance, full fairing, floorboards, audio, and electric reverse for easy parking. |
| Character | A rolling luxury lounge - stable, planted, torque-rich and unhurried, delivering effortless mile-munching with no need to balance or put a foot down. |
| Not Ideal For | Not for anyone chasing agility, canyon carving, track days, tight city filtering, or off-road use; it steers like a car, not a motorcycle. |
