Rider Profile
| Best For | Ideal for beginners and returning riders; the approachable 45hp twin, low weight and friendly ergonomics also make it a fun, forgiving second bike for intermediates. |
| Purpose | A lightweight middleweight naked built for commuting, city hopping and spirited weekend backroad rides, with enough legs for occasional short highway trips. |
| Rider Fit | Upright, roomy stance with a low 785mm seat and slim 165kg chassis. Easy reach to the ground, flat handlebar and neutral pegs keep it comfortable and unintimidating. |
| Character | Nimble, playful and easygoing. The parallel-twin revs eagerly, brakes and ABS inspire confidence, and the flickable trellis-framed chassis rewards without overwhelming. |
| Not Ideal For | Not for riders craving big-bore highway punch, long two-up touring, or any off-road use. Tall riders and those wanting relaxed cruising may find it small and buzzy. |
