How it rides
Editorial estimate from the spec sheet - not lab tested- 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.
