Best for
A nimble entry-level naked built for city commuting, learning throttle and cornering skills, and fun back-road blasts.
Built for
A sharp, playful single-cylinder streetfighter that punches above its 15 PS with aggressive KTM styling and eager, flickable handling.
Not ideal for
Not for riders wanting highway speed, two-up touring, or off-road duty; the modest 125cc output limits sustained fast cruising.

Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
