presentation of the Z 125 2019

The Z is the key to Kawasaki. A family of roadsters steeped in history. A Z 1000 that catapulted the brand to the forefront, a Z 750 with striking success, a 650 / 900 duo that is a must on today's market, a Z 1300 powered by one of Japan's rare 6-cylinders... But there's one displacement where he's never dared to venture: the 125 cm3. Yet it's the dawn of desire, a gateway to motorcycling intoxication. The greens are now on the offensive in this segment. With the Z 125, Kawasaki aims to offer the first thrills of a roadster.

Is Kawa playing big? No, Kawa is playing for position. There's no need to shock, dazzle or shake things up. This little roadster is a little provocative, but not too provocative, with good proportions, polished edges and a real personality. Not a big Z in miniature, but a real little Z to show off like a leader of the crowd. It's not provocative, as Kawa is known for; it's the charm of a youthfulness.

The Z 125 shares its technical base with its sporty Ninja sibling - a skirmish that is equally striking among small sportbikes. A liquid-cooled 4-stroke single delivers the requisite 15 horsepower. No more watts allowed. No competitor is better in terms of power, but the Kawa's weight doesn't allow it to compensate. At 146 kilos, it's far from being the lightest.
More eye-catching, the green-clad frame is a tubular steel trellis. It will be tempting for future owners to slip in the anecdote that the sultry H2 uses the same type of structure. Braking is provided by a disc at each wheel, bitten by two-piston calipers, including ABS.

With its slim tires, pocket-sized dimensions and assertive looks, the Z 125 promises to be both fun and rewarding. Comfort will be more important on the roadster, as the riding position is more upright, with handlebars higher than on the sports bike. Another difference is that the seat height is 30 mm higher on the Z than on the Ninja, even though both are built on the same platform. This is due to the thicker seat, which is more accommodating to the buttocks. The two-tone treatment of the seats is also very pleasing.

With the Z and Ninja, Kawasaki is finally able to offer bikes for the young (or not so young) who want to discover the world of motorcycling. And these machines are far from ugly. Successful design and a sense of quality are just some of the assets the roadster will bring to the table in a sector where the Katoche 125 Duke rules, in a small constellation where Mash, Yam MT-125, Suz GSX-S 125, Aprilia 125 Tuono, Honda CB 125 R and also...... orbit. Wow, there's a lot of them around. And yet, the Kawa is sure to get noticed.

Is 1.90 m too tall for a motorcycle?
French Viviking Model 2026
Hello,
I just saw the motorcycle at the Kawasaki dealership. Do you know if 1.90 m is too tall for the motorcycle? I tried it at the dealership, but I'm having trouble deciding.
Rating : 5/5
First 125 motorcycle
French Tintoons117 Model 2020
I'd gone for a Honda cb125 r, but it was sold out before 2025 (I bought it in August 2024), so I passed by Kawa and the Z125 2024 caught my eye straight away. I signed for it and rode away with my bike. Kawa knows how to make bikes, and you can tell when you ride it. It goes where I want it to, and does what I want it to do, without a hitch.
All I did was modify the exhaust, put retro bars at the end of the handlebars and a front bubble. I never ride on freeways, because I don't think a motorcycle should be on the freeway. I reach my 110 without batting an eyelid, and I don't ask for more. For a first motorcycle, learning to corner in town and on a plateau is the best thing you can do. And one last point: there are no electronics in the engine, and I can tell it's tough
Rating : 5/5
question conso ?
hello, I can't find the fuel consumption (manufacturer's data) for the kawasaki Z125, would anyone have this information please? Rating : 3/5
French unepersonne
After a long search, I found: average fuel consumption of 2.1 to 2.5 L/100 km, and range of around 400-450 km Rating : 3/5
Parfaite pour un débutant
French Vavel Model 2022
All the comments are spot on: it's not very peppy, it's a bit heavy, and it tops out at 113km/h. So why do I love it? Because it's my first bike, and I feel super safe with it. It goes where I want, it doesn't take me by surprise, if I panic all I have to do is cut the throttle and it slows down very hard on its own (I hardly ever have to use the brakes). In short, for someone looking to test their riding skills without putting themselves in danger, this is the ideal bike. That's my opinion, of course, and I understand that for those looking for a more reactive/"powerful" 125, this clearly isn't the bike for them, even if between 0 and 80 it really does hold its own quite well. Rating : 5/5
French Jeff2A Model 2023
For a return to the 125 segment, it's really not the best.
I had my first 125s in the very early 80s, and back then Kawasaki knew how to produce lively, light machines like the KE and KH, which weighed less than 100 kg for just 13 hp, but were much more expressive (2t) and powerful than a 4t 15 hp engine with almost 150 kg to move around.
With its rather short transmission, a KH could easily reach 130 m.p.h. With this kind of calf, it's easy to want to switch to the A2.
Rating : 1/5
French Crotale_furieux Model 2021
Expensive for what it is. I've driven it for 3700km, it's practical in town but a real pain on the freeway or even when you're driving flat out, so without going uphill, it's hard to reach 110km/h sometimes. I'd never buy it again, in fact I've since sold it, but it's still my first bike. Rating : 4/5
Moyen
French Kordac Model 2021
It's my first bike, and it's true that on the freeway it's a pain, barely reaching 117 km/h in the right conditions, and when there's an uphill gradient, it barely tops out at 90 km/h. Rating : 2/5
Amelioration personnel
French Model 2019
Good machine, pleasant to ride. Still lacks top speed. Can be fitted with exhaust and various accessories. On the other hand, it's quite expensive. Since I intend to keep it for a while, I've modified several points. Complete arrow line, kn filter, replacement: rear-view mirror, clutch and brake wrists + handlebar ends. I also changed my turn signals for leds and rebuilt the rear bracket. Installed led bulbs on the front light and I also fitted valve caps in the shape of engine pistons. And don't forget the kit installed at the time of purchase: rear seat cover, fall protection...now I'm left with no case to ride. Engine preparation is expensive. It's better to get an A2 license. I'm still satisfied with my purchase. Rating : 4/5
Z125 - BOF
French Model 2019
I recently tested the bike and compared it to my GSXS 125
.
Positive points:
- Nice finish, nothing sticks out
- Very good braking
- Smooth gearbox
- Good chassis
.
Negative points :
- No feeling at the throttle, you can hear the engine "scream" when you turn the throttle, but nothing happens before half the stroke, it's sluggish and unresponsive
Once started, it's still okay, but...
- Poor/fade rev counter, no gear indicator, speedometer/engine locked at 10,000 rpm, so max speed 110 km/h (for 15 hp)
- Quite heavy for a mono


For the price, I think it's a pity, because it's a good value and has the maximum legal power, but the 15hp are invisible when you're riding it.

My GSXS 125 is much more responsive for the same advertised data and for 700 euros less.

It's a pity, a real pity, because it's a real eye-catcher

\But there's one displacement he's never dared to venture into: the 125 cm3," says Motoplanete.
What about the 125KH of the 70s?
Rating : 1/5
Perhaps we misspoke. We didn't mean that Kawasaki never ventured into the 125 class, but that the Z never had a 125 version. Rating : 5/5
French
I really don't regret taking my A license, because the 125s of today, especially since the disappearance of the 2-stroke engines, have no character with their little 15 hp, especially with a kerb weight that exceeds 120 or even 130 kg for most of them.
They have a hard time reaching 130 km/h, which makes them unsuitable for freeway use, and even dangerous.
And yet, with today's engines, it's possible to get at least 25 hp out of a 125cc 4-stroke engine and design a motorcycle that can be used safely, given the quality of today's braking systems. Perhaps the AL license should be adjusted in terms of maximum power, and a middle ground found between the 15hp and 34hp of the old A license for beginners.
