In a market dominated by learner-friendly nakeds and commuter scooters, the Kawasaki Ninja 125 stands out as an almost unique gateway into the sports bike world. For new riders starting out on L plates but still craving that sporty look, feel, and riding position of a bigger, faster machine, the smallest of the Ninjas offers a distinctive blend of style, performance, and manageable personality. Just without the licence-breaking power.

This is my Ninja 125cc, affectionately known as Stacey, which I have had the privilege of spending the last 15 months and nearly 9,000 miles riding, putting her through everything from tight B-road twisties to long stretches across the Cotswolds and Wales.

When I bought her in May 2024 from the (now sadly closed) Completely Motorcycles in Gloucester, I hadn’t evenseen Stacey in person. She was the bike I wanted so I put down a deposit there and then. Yet the gamble paid off. Rather than the ubiquitous lime green Kawasaki livery, mine is the rarer stealth black, giving a sharper, yet more understated edge. It looked rare and still gets a few heads turning now. It cost just under £5,000, which is competitive for a premium 125 sports bike that looks this good parked outside a café. Kawasaki has clearly drawn from tesign team responsible for hteir bigger Ninjas . From the fairings to the tank profile, this isn’t a “baby” bike trying to look like a sports bike – it is a sports bike, just in 125cc form.

At 5’5” and under 10 stone, I was a little concerned it might feel tall or unwieldy. The good news is the 785mm seat height is low enough for both feet down at the lights, and the narrow frame makes it easy to manoeuvre and light once it’s upright. Straight from the dealer, the suspension was on the firm side. Any bike is built as a one size fits all, so for a smaller and lighter person adjustments are always needed. A slight tweak making the suspension softer has transformed my ride, making cornering crisper and improving comfort on longer runs. There's no getting away from the fact that this is a learner legal machine - under the fairings beats a liquid-cooled, single-cylinder, four-stroke engine producing just shy of 15bhp – the legal limit for A1 riders. Kawasaki claims a top speed of around 74mph, and it seems that's pretty much bang on. Once you hit that, the bike politely says, “That’s enough.” From a standstill, though, it’s a different story. Acceleration is lively and surprisingly quick, which makes town riding effortless. Slip through traffic, pull away from lights, and you’ll forget you’re on a 125. On dual carriageways, you’ll hold 65–70mph comfortably, though overtakes require some forward planning. Which is good, because as a new rider, you need to gain that thought process of looking far ahead and the Ninja encourages you to do that, making you a better, safer rider. (Bet you never thought you'd read a limitation in performance being sold as A Good Thing. Ed.)

The ride is smooth, with the occasional quirk. On smooth tarmac, the Ninja is as composed as you’d expect. It tips into corners willingly, holds a line confidently, and feels stable at lean. However, like most lightweight sports bikes, it’s not immune to tramlining. Uneven or worn surfaces and stretches where loose chippings have settled can make the ride feel a bit bumpy and the back wheel is inclined to twitch. It’s never enough to properly unsettle the bike, but it's uncomfortable until you get used to it.

The clutch is light and forgiving, which is perfect for new riders. I’ve made a couple of minor adjustments to to the lever position for quicker, smoother shifts – something anyone can do with a spanner and five minutes. L

In the last 15 months, my Ninja’s had two services – the first at 900 miles, the second at 7,000 miles. Other than routine maintenance, it has been a paragon of reliability. It starts first time, every time, although it can be temperamental with neutral when hot and you feel your right leg start to heat up yet overall, she has given me the confidence to push her limits, even in slow moving traffic and hill starts. The key is to give it the beans with plenty of throttle and good clutch control which can be mastered almost immediately. Running costs are as low as you’d expect from a 125. Tyres last ages and standard tyres are hard compound. Fuel consumption is excellent (easily 90mpg if you’re sensible), and insurance is friendly for new riders, especially if you are already a car driver with a few decades under your belt.

I’m currently working towards my A1 licence, with the Mod 2 test (which assesses your ability to ride safely in various road and traffic conditions) in early September 2025. Once I pass this, the L plates will come off, and the Ninja will really open up for me – I’ll be able to hit the motorway legally, take a pillion, and tackle longer trips without restriction. There are also exciting future plans in the works: like a performance air filter to squeeze out a bit more acceleration and nudge that top speed higher. The tinted windscreen I’ve already fitted has given it a more aggressive look, and I suspect this won’t be my last tweak. The Ninja 125 is not just a bike, it's a canvas for your personal style and performance preferences.

The Kawasaki Ninja 125 is more than just a stepping stone to a bigger bike. It’s a well-built, great-handling, confidence-inspiring machine in its own right. For new riders who want style, performance, and a taste of the sports bike life without the jump to a 600 or 1000cc, it’s hard to beat. It’s forgiving enough for complete beginners yet engaging enough to keep you hooked long after you’ve passed your test. After nearly two years, I’m still excited every time I open the garage door. And for me, that’s the mark of a truly remarkable first bike.
