Z125 (MY2019)
Kawasaki's Smallest City Knife
The Machine's Character
The Z125 is a real motorcycle scaled down, not a toy scaled up. Kawasaki gave it a liquid-cooled 125 cc single making 15 hp at 10,000 rpm and 9 lb-ft at 7,700 rpm, fed through a six-speed box and a chain. It hangs in a steel trellis frame on full-size 17-inch wheels, with an 11.4 in (290 mm) front disc and ABS as standard. At 322 lb (146 kg) wet, it carries the sharp Z-family look without the weight or complication. That is the Kawasaki recipe I respect: an honest, working package with nothing added for show.
On the road it is about as approachable as a naked bike gets. It steers with very little effort, slips through city traffic easily, and the controls ask nothing of a new rider. It is built to last, costs little to run, and there is plenty of aftermarket support if you want to personalize it later. It suits new riders, city commuters, and experienced riders who want a cheap second bike for short trips. The honest caveat is 15 hp. Freeway work is not its job, the fork has no adjustment, and past urban speeds you are keeping the engine near the top of its rev range to make progress.

Any price note compares both bikes at the same age — the youngest age both have on the used market — against this Kawasaki Z125. “cheaper/pricier” is what that bike costs second-hand, not how worn it is.
