Our detailed review one of the legends of the motorcycle world, the ever faithful little Yamaha YBR 125!
At ACBT London we have quite a unique collection of training bikes. We don’t just settle for the usual. Training schools up and down the country generally offer pretty much the same bikes. We like to be different in every respect, in our brand image, our methodology, our outlook and also in our training bike collection. We don’t just tie in with a motorcycle dealer and take what we’re given. We value our independence and this allows us to make the right choices. We also think about you, our customer, as we want to make sure you are given the best possible tools for the job at hand whether you are taking your CBT or in a DAS or PAS course. We therefore spend a lot of time curating the best collection of motorbikes for our customers to train on.
If any motorcyclist were asked to name legendary motorcycles I guarantee the Yamaha YBR would be nowhere near the list.
Humble learner, every day bikes for commuters don't deserve that accolade do they? They're not glamorous or exciting, they may not get the pulse racing but that doesn't mean they are not utterly and indubitably, brilliant.
The Yamaha YBR 125 is definitely one of those. A motorcycle as excellent as it is understated. I wonder how many motorcyclists around the world can look back to time spent on a YBR at the start of their motorcycling adventure. It has been a mainstay of motorcycle training schools over the years because of its ease of riding and dependability. It still makes an excellent first bike.
Even though it's not manufactured for our markets any longer in some parts of the world it still thrives. Some time ago we reviewed the Honda CB125F, another bike we consider legendary and the intention was always to devote a page to Yamaha's superb rival to the Honda.
About the Yamaha YBR
The Yamaha YBR was introduced in 2005 to replace the equally successful SR125, which was, incidentally, the bike I learned to ride on.
They released it in standard, custom and off road versions. Up to 2007 they had a carburetor and from that date onwards they used a fuel injection system.
It remained virtually unchanged up until 2017 when a new and final version was released known as the YS125 to comply with Euro 4 requirements. This included linked brakes and a general facelift to make it look more "modern" with a small cockpit fairing which arguably made it lose some of its traditional charm. The YS was the final version of the legend which was then replaced in the Yamaha line up by the XSR125 which, whilst popular, is more of a premium product as opposed to a simple entry level motorcycle and will never achieve the level of popularity of the original.
Overview and design
A simple, reliable naked-style 125cc motorcycle with a straightforward, functional design. It features a diamond-shaped steel frame, a basic but sturdy build, and classic commuter styling with a small front cowling on some variants, an analogue instrument panel (including tachometer), and a roomy dual seat with a rear luggage rack. It's not flashy or sporty — it's a workhorse meant for daily commuting, short trips, and learning to ride.
It was positioned as an affordable, low-maintenance entry-level bike, often used in riding schools.
Performance and Riding Experience
Don't expect excitement, this is a humble commuter.
The engine delivers smooth, forgiving power with a broad torque curve that's ideal for beginners.
It pulls away from lights easily in town and cruises comfortably at 50–60 mph (80–95 km/h). Real-world top speed is around 65–70 mph (100–110 km/h) on flat roads with a solo rider, though it struggles more with headwinds, hills, or a passenger.
Acceleration is modest (0–60 mph in the 15–20 second range depending on conditions) but having said that it is lively enough to keep you ahead of traffic in town. The 5-speed gearbox shifts smoothly, and the light clutch makes it easy in stop-start traffic. Fuel injection provides responsive throttle and excellent cold-start reliability. Vibration is low at cruising speeds, though it can buzz at higher revs. Fuel economy is one of its strongest points: Real-world figures often hit 85–100+ MPG (2.5–3.5 L/100 km), with many owners reporting 90–120 MPG on gentle riding. The tank gives a realistic range of 200–300+ miles (300–480 km), making it perfect for long commutes without frequent stops.
Handling and comfort
Light weight makes it very maneuverable in city traffic and easy to flick around.
Steering is neutral and predictable, though the narrow tires and basic suspension mean it's not what you'd call "sporty" when cornering although they are surprisingly grippy and it feels stable enough for its purpose but can feel bouncy over rough roads.
The upright riding position with high-ish handlebars is comfortable for most riders, with a roomy seat good for daily use. Wind protection is minimal (as expected on a naked bike). Braking is adequate for the performance level. The front disc offers decent bite, while the rear drum is basic but functional. The Custom version had higher pull back bars with a wider seat.
The low seat, light weight, forgiving power delivery, and easy maintenance make it ideal for new riders.
Reliability
Ask anyone who has ever owned a YBR about reliability and you-ll hear the same reply, "bulletproof". Many examples exceed 50,000–100,000+ miles (or even 300,000+ km in some reports) with minimal issues. It's a favorite for learner bikes and daily commuters.
Economy, running costs and practicality
Cheap to insure, service, and run. Parts are widely available and affordable (including aftermarket/Chinese options since it was built under Yamaha supervision in some markets). Good storage on the rear rack, simple design, and low maintenance needs (valve checks are recommended at service intervals).
Performance
It isn't fast, let's be honest, but it doesn't need to be. It's a 125 commuter bike. Even the most flashy (and more expensive) premium level 125cc motorcycles are limited in power. Why spend £5000 on a new modern 125 when one can buy one of these little gems for as little as £800? It's built for a purpose, to learn on. Buy a YBR instead, ditch the pride and save the cash for the time when you pass the test and buy a bigger bike with more power. On fast roads it will feel buzzy and under powered but again it's not designed for that environment.
Ride quality
Ergonomically it is comfortable. The reach to the bars and pegs is natural. Controls are easy to use. With some confidence the skinny tyres will offer a surprising amount of cornering stability whilst the instruments are unobtrusive and look good actually, in a simple, traditional way.
They tell you what you need to know...how fast you're going and how much fuel you have left! Gear indicator? Nope, it's superfluous anyway! The suspension and brakes do enough of their job. They work and that's all you need. It is possible to upgrade them if you wish to but why? Just leave it alone as it is and save your cash for the big bike. This is a no frills, no fuss motorcycle and that is part of it's charm. You will arrive at your destination at the same time, if not before, your mates on their flashy XSR or YZFR125s. Every time I ride a YBR (we have two in our fleet) I always get a smile on my face. It is so much fun.
Long-term
Reliability is excellent. Just change the oil every now and again and look after it, same as any other bike. If you do it'll outlive cockroaches after a nuclear war. And the best bit? When you eventually sell it you'll probably get back what you paid for it. They seem to hold their value very, very well.
Who should consider a YBR?
Complete beginners or learner riders will find it a great way to learn. Budget commuters who want cheap, reliable transport to work or college without drama. Anyone needing a frugal, low-maintenance runabout for city and short suburban rides. As I write this the USA is bombing seven tons of hell out of Iran resulting in a massive price of fuel increase, thank you Donald Chump! Fuel prices here in our part of London have increased by more than 20p per litre in the space of the last three days. The frugality of the YBR makes it a terrific solution until things return to normal. It won't win any performance awards, but it excels at being cheap to buy, run, and own while delivering fuss-free daily riding.
The verdict
I think by now you will have formed the idea that we are very positive about the YBR. In the last 35 years I have owned more than 60 bikes and have actually ridden hundreds. I cannot fault the YBR. Many of our trainees ask what bike they should buy after completing CBT and the YBR is one of the bikes we always recommend without hesitation.
Similar alternatives
Whilst the YBR is no longer sold in Europe (it is still available in other markets) the spirit lives on in a number of Chinese built derivatives. The best of these in my opinion is the AJS Tempest Roadster.
It retains the same simplicity of the YBR, shares the engine and mechanicals but is more comfortable, has disc brakes front and rear, and is a really smooth ride.
The Tempest can be found for as little as £1100 second hand whilst new they sell for £2800. We have three in our fleet so can attest to their quality and reliability.
Second hand YBRs generally range from as low as £700 for a tatty but running example to over £2000!
Other legendary 125s on a par with the YBR are legends such as the Honda CG125, the Suzuki GN125 and the Honda CB125F. Expect similar second hand values to the YBR but are just as good in every way.
