Reliability and upkeep
This model is $800 more than the Kawasaki KLX110R youth trail bike at $2,999 and $200 more than Honda's Grom at $3,599. The 2.0 gal tank is the smallest in Kawasaki's road range. So it is a town bike.
At 224.8 lb curb it is easy to move, and a new rider or a parent buying for a teenager should check local rules on the license needed for a 125cc bike. Budget for a helmet and riding gear.
Sit on the bike, since a 125cc mini naked bike has a small frame and a taller rider may find it cramped. Ask about the four-speed gearbox and how it behaves on a hill. Check the license rules for a 125cc bike where you live.
Look at the tires, the chain and the brake pads. A used Z125 Pro may have been ridden by a new rider, so check for tip-over damage on the levers and footpegs. Ask what the warranty covers, and compare the price with Honda's Grom.
Z125 Pro against the Grom, Monkey and W175
Honda's Grom costs $3,599 and weighs 224 lb, essentially the same as the Z125 Pro at $3,799 and 224.8 lb, and Honda's Monkey is $4,399. Kawasaki's Kawasaki W175 is the cheaper retro option at $2,999 with a bigger 177cc engine.
Kawasaki Z125 Pro — specification referenceWhat the launch test found about rider room
In Spurgeon Dunbar’s May 2016 ride of the 2017 Z125 Pro, the 6 ft 3 in tester reported his knees contacting the handlebars. He also needed repeated downshifts on San Francisco’s larger hills. Those observations concern that tested edition and rider, not a measured top-speed or fit guarantee for the 2026 bike.
The Z125 Pro is a friendly, small bike. Total Motorcycle lists a four-speed manual transmission, smooth power delivery, a lightweight chassis, an offset laydown single shock and a digital LCD with an analog tachometer and gear position indicator. GearHonest says the low seat height gives ergonomics that suit handling and comfort, and that the chassis and seat make the ride comfortable, and that the 2-gallon tank is enough for long stretches.
Motoryk says Kawasaki built the bike properly, with real suspension, disc brakes front and rear and a fuel-injected 125cc single that is genuinely reliable, and that the air-cooled engine needs minimal maintenance. Its one critical owner issue is rear brake pads that are ignored until they grind metal on metal and the rear brake feels weak, so check the pads on a used bike.

Kawasaki rates the 125cc air-cooled single at 10 hp and 7.1 lb-ft, with a four-speed return-shift gearbox. It is a city and back-road bike.
Motoryk names worn rear brake pads as the main issue: owners ignore them until they grind metal on metal and the rear brake feels weak. Check pad thickness and rear brake feel.
