Rider Profile
| Best For | Ideal for beginners and returning riders; forgiving power delivery and light weight also make it a fun commuter or track-day starter for experienced riders. |
| Purpose | A lightweight sport bike for spirited canyon rides, commuting, and entry-level track days rather than long-distance touring. |
| Rider Fit | Compact and light at 164kg dry with a manageable 785mm seat; sporty but not extreme riding posture with mild forward lean and small windscreen. |
| Character | Nimble, approachable, and revvy parallel-twin sportbike that punches above its 399cc for grins without intimidating newer riders. |
| Not Ideal For | Not for riders wanting big-bore highway punch, two-up touring range (tiny 3.7L tank), or any off-road use. |
