2021-on Husqvarna Svartpilen 125

Engine size: 125cc Power: 15bhp Weight: 146kg Seat height: 835mmPrice: £4799

Based on the KTM Duke 125, the Husqvarna Svartpilen 125 is a grown-up take on the naked learner-legal category. The new baby Svartpilen sits below the 401 and 701 versions and has the same distinctive styling.

Unlike the KTM, the Husqvarna forgoes a flash TFT dash in lieu of a more modest, round LCD unit more in keeping with the style of the bike. A comfortable bike, with plenty of room for the taller rider. It also comes packed with decent suspension providing the rider with enough adjustment to dial in the ride.

2017-on Aprilia Tuono 125

• Get the look: Best motorcycle kit for beginners.

Engine size: 124cc Power: 14.8bhp Weight: 120kg Seat height: 810mm Price: £4650

How’s this for a sporty-looking 125? It’s styled to look just like its bigger brother, the Tuono V4 1100 and features lots of modern kit to back up the looks. Big bike cred is backed up by peppy performance and some of the hottest handling in the sector. Light weight and an medium to low seat height thanks to the single cylinder makes it enticing option for any shorter riders.

2019-on Kawasaki Ninja 125

Engine size: 125cc Power: 14.7bhp Weight: 148kg Seat height: 785mm Price: £4299

For 2019, Kawasaki have returned to the 125cc A1 class for the first time in 25 years with not just one, but two new learner lightweights. There’s the Z125 naked roadster and this, a fully-faired, sports-styled machine based on the same engine and chassis. The result is eye-catching, attractive, sporty and instantly identifiable as being part of the Ninja family. Performance is on par with the competition.

2017-on KTM 125 Duke

Engine size: 124cc Power: 14.8bhp Weight: 128kg Seat height: 785mm Price: £4799

Classy, simple and fun supermoto-style single delivers the double act of being an easy to ride learner bike with bags of street cred. It was updated in 2017 when it received a new TFT dash plus a revised frame and styling, and now even has the option of integrating a smartphone with the dash, allowing the rider to access incoming calls and listen to music via a Bluetooth headset. Smaller learner roadsters don’t get any cooler than this naked Austrian headbanger-in-the-making. A low seat height and weight make for an accessible package for all.

2014-on KTM RC125

Engine size: 124cc Power: 15bhp Weight: 135kg Seat height: 820mm Price: £5199

This faired, sports version of the 125 Duke features a lovely free-revving engine, handles well and boasts some neat touches like the side-mounted exhaust and bellypan combo. Sadly, the 2017 model wasn’t updated in the same way as the Duke, so if you plump for this sportier option you’ll have to make do without the full-colour TFT dash. Plus, the WP suspension isn’t properly sorted, so it does tend to protest and chatter a little when used hard.

2017-on Suzuki GSX-R125

Engine size: 124cc Power: 14.8bhp Weight: 134kg Seat height: 785mm Price: £4999

With a very sporty riding position (as you’d expect from a GSX-R) and, in true Suzuki tradition, it’s priced very attractively, too. The GSX-R125 is another bike that’s built in the Far East (Jakarta, this time), to keep costs down but, unlike other Far Eastern 125s, its aimed more at the European market so has an excellent power-to-weight ratio and is very economical. It looks super, especially in the slightly pricier MotoGP colours and has remote keyless ignition, as well.

From 2023 onwards and with the demise of the Suzuki GSX-R1000, the GSX-R125 stands alone as the only sportsbike in Suzuki’s range, too.

2020-on Yamaha MT-125

Engine size: 125cc Power: 14.8bhp Weight: 140kg Seat height: 810mm Price: £5100

Essentially a naked, roadster version of Yamaha’s all-conquering YZF-R125, the MT-125’s ‘Dark Side’ styling, taking its cues from Yamaha’s MT-07 and MT-09, won’t appeal to everyone but its engine has a surprising amount of grunt for a 125, making it more useable on faster roads. It’s also light and agile in traffic and, while not being very high-tech, is a solid 125 with proven mechanicals and decent features.

Read full Yamaha MT-125 review here. Also it is worth considering Yamaha’s retro styled brother that shares the same MT platform, the Yamaha XSR 125.

2019-2022 Yamaha YZF-R125

Engine size: 124cc Power: 14.6bhp Weight: 127kg Seat height: 818mm Price: £5300

Introduced in 2008, the R125 took over as the sports 125 to appeal to every red-blooded teenager thanks to its full-size proportions, full-quota performance and R6 looks.

Yamaha saved cash by employing a steel frame and basic non-adjustable suspension, but its digital dash, underslung exhaust and Brembo brakes made up for that. For 2017, it got a new fuel injection system, revised engine internals, updated styling and new instruments, and for 2019 it’s had yet another makeover that’s sure to keep it at the top of the tree in this sector. Yamaha have a rich history of building great 125s, like the YBR 125 from 2005, which was on sale until 2020.

2019-on Kawasaki Z125

Engine size: 125cc Power: 15bhp Weight: 146kg Seat height: 815mm Price: £3999

The Kawasaki Z125 naked roadster was launched alongside its also all-new faired Ninja 125 sportster in 2019 and marked a return to the 125cc A1 licence class for Japanese firm after a 25-year absence, apparently after an ‘extensive’ market research program by its R&D team revealed a hunger for bikes in this segment.

2021-on Honda Grom MSX125

Engine size: 125cc Power: 10bhp Weight: 103kg Seat height: 761mm Price: £3000 (used) – £3899 (new)

Honda’s latest cult hit, selling over 750,000 units across the globe. The 125cc mini bike is simple, nimble, and brings a new joy to nipping across town. With the lowest seat height listed here, and weight, its super accessible, without being disproportionate or clown like. The ergonomics are good and can comfortably fit a rider, without having knees and elbows flaring outwards. First introduced in 2014, and later upgraded for emissions in 2021, there are models available for a decent deal. If its just town and urban riding you are after this could be the fun next step in your riding career.

2021-on Sinnis Terrain 125

Engine size: 125cc Power: 13bhp Weight: 162kg Seat height: 780mm Price: £2800 (used) – £3599 (new)

A lot of bike for the money, with big bike feel and roomy ergonomics. However, what gains you get in size and weight from hard panniers, crash bars and big bike dimensions, you loose in performance. Being that bit heavier and underpowered for the class, it comes across as an underwhelming ride. That being said, it is the only adventure styled bike of the 125cc class, so if that is what you are after, it could be a fair compromise.

Super Soco TCMax

Engine size: Electric Power: 6.7bhp Weight: 100kg Seat height: 770mm Price: £3699

The Super Soco TC Max may be down on power compared to the others but with its high torque electric motor and incredibly low weight, you’d be hard pushed to notice. The TC Max feels more like a very fast push bike to ride and zips up to over 60mph no problem. Best of all, you get a built in tracker (through a smartphone app) keyless ignition and a motion-activated alarm as standard and if you try to wheel it away without unlocking it, the motor fights against you.

2022-on Maeving RM1

Engine size: Electric Power: 6bhp Weight: 124kg Seat height: 785mm Price: £5995 (new)

A new kind of electric motorcycle built in the UK, retro styled, with intention of having swappable batteries. Its hub-mounted electric motor is built by Bosch and the battery packs are produced by Samsung. It’s an outright urban machine, so its intended use should really be considered – it’s not going to be great at the national speed limit… Even so, it’s a charming bike with great details and features which add value to the package and ownership.

Who can ride a 125 motorbike in the UK?

If you’re learning to ride and aged 17 or older, after passing your CBT certificate (Compulsory Basic Training) you can gain your provisional A1 bike licence, which allows you to ride up to 125cc motorcycle on the road, producing a maximum of 11kW (15bhp) power output with a power-to-weight ratio of not more than 0.1kW per kg.

You’ll have to wear L-plates, avoid motorways and won’t be allowed a pillion, but it’s a great gateway into bigger bikes and the joy of road riding.

Next steps in learning to ride a motorcycle:

• Motorcycle theory test and hazard perception exam
• Pass module 1 riding test
• Pass module 2 riding test

Case study: Finding a bike for our learner

MCN tests all kind of machines, but you could argue 125s are the most important. They offer an affordable and practical means of transport for the masses, but for many they’re also a gateway to a lifetime on bigger bikes.

The latter is true for 22-year-old Joseph Wright, MCN’s videographer (and the reason the quality of our YouTube videos has stepped up a gear). He’s at the beginning of his biking journey and closer to the world of 125s than crusty old road testers like me.

He says: “Before working at MCN bikes hadn’t crossed my mind and I never knew anybody with a bike. But being surrounded by them I got the bug, so went off and did my CBT. It was surprisingly easy and took just four hours. I scanned the classifieds for a couple of weeks, until I found a lovely 2012 Yamaha YBR125 with 17,000 miles on the clock.

“I chose it because it was cheap and reliable. I was looking at a few Chinese bikes that looked nice, but a lot of people warned me against them, saying I’d have problems; so I took their advice and went for a bigger named brand. The Yamaha was a good starting point: low, light, manageable and easy. 

“I’ve loved riding it for the last year. There’s a massive stigma that comes with L-plates. People don’t want to be labelled as not as good as someone else, but if you can get past that it’s fine. My longest ride was around eight hours and the bike did 70mph, which is the speed limit, anyway.

I think it’s good to learn to ride in stages. If you jump straight to a big capacity bike it’ll be a massive shock. The 125 was a surprise because it was still fast and as I hadn’t experienced a bigger bike at that point, it was brilliant. It was cheaper to run than my car, better on fuel, accelerated faster, was quicker from A to B, and a lot more interesting. I used it every day for commuting and did 4000 miles, before recently taking my full test and buying a Kawasaki ZXR400.”

So, who better then Joseph to put a bunch of new 125s to the test? We asked him to choose the three bikes he’d buy if we gave him a budget of up to four, five or six grand. We gave him the keys for two weeks and told him to go off and do what he wanted with them, which turned out to be around 150-200 miles on each, commuting and doing whatever 22-year-olds get up to…

Interestingly, the 125s he chose are retro/scrambler, style, as he explains: “As I move up through, I’ll enjoy sportsbikes, but I think things bikes the Yamaha R125, are trying to be something they’re never going to be with sub-15bhp. That’s why these appeal. They’re not super focused, just comfortable, manageable and could do anything from a little light off road to touring. They’re Jack of all Trades, and I like the trendy looks.”

2021-on Zontes G1 Scrambler 125

Engine size: 125cc Power: 14bhp Weight: 160kg Sea height: 795mm Price: £3499 +OTR

First impressions: “I want to try a budget Chinese bike, just to see what one is actually like. The Zontes looks really good and I wish I could have tested it when I bought my YBR.”

After riding: “It’s been mechanically flawless and the biggest surprise of the test. It’s super-easy to ride and performance is on par with the others, although you’re stuck at 60mph until the engine really warms up, then it gets to 70mph. The gearbox is slightly lazy and not as accurate as the others.

“I like its low seat, which is what you want when you’re learning and it’s easy to both feet flat on the floor at the lights. The riding position is relaxed, neutral and it’s heavier than the others, but it’s a 125, so still light and it’s the most fun in the corners. The bars are narrow and you’re low to the ground, so you can lean it over more and feel like a hero.

“The Zontes would’ve been my first choice when I took my CBT, but now I’ve got more experience it feels soft and not as rewarding as the others when you push it hard. But nothing about the fact it’s Chinese puts me off and it feels very much like my old Yamaha YBR125. I haven’t ridden it for long enough to test its reliability, but you get a lot for your money: crash protection, adjustable levers and a 20-litre tank that gives it the feel of a big bike.”

2018-2020 Honda CB125R

Engine size: 125cc Power: 13bhp Weight: 126kg (dry) Seat height: 816mm Price: £4599

First impressions: “I really like the Honda CB range and this has big bike proportions and a lot of presence. Those were my two biggest things when I chose my 125. I think scooters and delivery riders get pushed around and no one really cares about them. Being upright with wide flat handlebars appeals to me and I’d hope I’d be treated the same as I would on a bigger bike.”

After riding: “I wasn’t blown away by the Honda at first and thought it was very middle-of-the-road, but by the end it grew on me and became my favourite. It’s the bike I had the most compliments on, which surprised me – I thought the Fantic would attract more attention.

“Although it is a naked, the riding position is sporty, which I like and it’s super-accurate going through the gears. The suspension is brilliant, the brakes are the best here and with road tyres instead of knobblies, you can go a lot faster through the corners.

“But the throttle and steering are very light, which I know should be a good thing, but I like having a bit of resistance to push against. It’s very comfortable and quite tall, but about right for me. If you were less than 5ft 6in and a new rider you might struggle.”

Fantic Caballero Scrambler 125

Engine size: 125cc Power: 15bhp Weight: 130kg (dry) Seat height: 820mm Price: £5569

First impressions: “This is the holy grail for me – really cool, but ridiculously priced. The performance shouldn’t be different to the others, so it’ll be interesting to see if it’s worth it for the styling and all the extra bits”

After riding: “It feels bigger than a 125, which surprised me and isn’t new rider-friendly or forgiving as the others. It’s immediate and accurate on the throttle, sounds great and has the best acceleration, although top speed is around the same.

“It’s by far the lightest bike I’ve ever ridden and one of the biggest, too. The bars are high and wide and the seat is tall. I’m 5ft 8in and can’t get my feet flat on the floor, just a toe on one side. If you were smaller than me that would make your decision for you. It’s not great for turning in the road, either, but the grab handles make it easy to manoeuvre around the garage.

“I like the styling, apart from the yellow number board, which looks a bit childish. The switchgear buttons have a nice firm action too, unlike those on the Zontes, which feel loose and the Honda’s horn switch sticks out too much and is too easy to press by mistake.

“It looks stunning, sounds the best and, money-no-object, would be a lovely thing to have. Fantic have spared no expense by taking the 500 version and just replacing the engine with a 125cc, which you could view as a good thing, or lazy.

“But it’s not pitched at someone like me. It’s too much of a nice thing to drop, especially off-road, which would make me enjoy it less. I’d be gutted if it went over. It’s hard to place, as it’s just so nice to look at.”

Greatest of all time (GOATS)

It’s hard to call them the greatest of all time, or the GOATs, for their simplicity or lack of thrills. However, in spite of being a little lacklustre nature (with the exception I mention below) these 125cc bikes have long since been the staple of the category with many thousands of bikes sold and an impressively long production life to prove it. Serving riders with a budget-friendly super-reliable bike for many years, surely that deserves some recognition? Maybe not the GOATs, then, but worth sharing here. With plenty of models still available on the market today, these could provide a more budget friendly entry point to the next step in your riding career.

1975-2008 Honda CG125

Engine size: 125cc Power: 11bhp Weight: 114kg Seat height: 781mm Price: £1500 (used)

Serving as the ultimate commuter bike for the last 30 years, they sold in huge numbers amassing ten million sales world wide.

The Honda CG 125 goes, it stops, it goes again the next day – simple as that. Ultimately it does exactly what it says on the tin. With smaller proportions its unthreatening and easy for any rider to jump on and to get to grips with. Very easy to work on and maintain, they are long lived with chunky controls an overall robustness and plenty of spares available should they be needed.

2005-2020 Yamaha YBR125

Engine size: 125cc Power: 10bhp Weight: 113kg Seat height: 760mm Price: £1500 (used)

Frugal, basic, very much the budget commuter, and it full-fills that role brilliantly. Updated a few times over its years and even spawning a custom cruiser version the Yamaha YBR125 Custom, the base model and components remained the same, a simple fuel injection system designed to be cheap, and reliable. Certainly a more flexible choice than that of public transport and that could account to being the reason why 50,000 of them were imported into the UK.

1995-2012 Aprilia RS125

• Keep it gleaming: check out the best motorcycle cleaning products here.

Engine size: 125cc Power: 15bhp Weight: 126kg Seat height: 805mm Price: £2000 (used – expect to pay more for a relatively good example)

A diamond in the rough, one of the must have bikes of the 1990s one of the coolest 125s that any budding new rider could slap an ‘L’ plate on. The only two stroke in our list, but a mighty one. Legally producing 15bhp as the limit of what can be ridden in the 125cc class. Gone are the days that you will find one of these bikes that hasn’t been tampered with in some way, be that professional, or a DIY version to derestrict and unless some more ponies. That is sole reason when buying one of these bikes, ensure you have decent evidence of work well done, for any ‘derestrictions’ or ‘recent engine rebuilds’. Besides all of that, it was a sweet handling bike for its class.

Top tips when buying a used 125cc

• Engine and frame numbers: check they match up to the V5 (vehicle logbook).
• Chain and sprockets: check them for wear, its a good indication of whether the bike has been well cared for.
• Consumables: like brake pads, tread left on the tyres these may need replacing so it can be used as a good negotiation point.
• Electrical gremlins: and aftermarket items, check the wiring loom where possible, if any aftermarket parts have been added; heated grips, or additional lights etc look for tidy wiring and neat connections. Its very easy to overlook the loom and then run into problems after you have bought the bike. You then have to unpick the birds nest of cabling carried out by the previous owner, making it difficult to diagnose any issues.
• Engine: an obvious one, is it running? Check that the engine starts and runs from cold and hot, making sure it doesn’t have any horrible noises or rattles. If the seller allows it, take it for a test ride and make sure you can select through the gearbox smoothly.
• Road Tax (VED): it isn’t transferable to the new owner when a bike is sold, so be sure to renew it before you hit the road. Additionally, a bike with a current MOT is a more reassuring buy than one that hasn’t got it. Be wary of bike sales which describe the a bike sating ‘it will fly through’. It’s better that the seller fund the MOT and any potential issues flagged by it, rather than you find them out after the sale.
