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.
