2012 Yamaha YZF R125 | Used Bike for Sale UK

This is a 2012 Yamaha YZF R125, listed for sale at £1,350. The seller hasn’t stated the mileage, so you’ll need to ask for that directly, and while no specific location is given, delivery is available if you ask. It comes with a fresh MOT and a keyless start system that the seller says has been wired in properly.

Key Features

Condition and History

Let’s be straight about what the seller has told us, because that’s all we can go on here. The bike is described as being in genuinely good nick. The words used are “absolutely stunning” and “basically mint,” with the only negatives being “a scratch or 2.” So it’s not a concours showpiece, but it’s clearly been looked after and presents very well. If you’re fussy about cosmetics, those one or two scratches are worth asking about in detail before you travel to view it. Where are they? How big? Are they through the paint or just light marks? Those are fair questions and any decent seller will answer them.

The mechanical side of things sounds equally positive. The seller states it “runs and rides as should,” which is a simple but reassuring way of saying there are no known running issues. It’s not a guarantee, but it’s a decent starting point. The big one for many buyers is the MOT. This bike has just had a full year’s MOT put on it. That means you don’t have to worry about booking a test or budgeting for that expense for another twelve months. A fresh MOT also gives you a bit of confidence that the bike has been looked over recently by a tester, even if an MOT is not the same as a full mechanical inspection. It covers the basics like brakes, lights, tyres, suspension, and emissions, so any glaring safety issues would have had to be sorted.

Now, the keyless start. That’s not standard on a 2012 YZF R125, so this is an aftermarket addition. The seller has gone out of their way to point out that it isn’t one of the cheap kits that can cause problems. Those budget systems sometimes fail to account for the bike’s neutral and clutch safety switches, which can lead to the starter motor being engaged while the bike is in gear. That’s a quick way to burn out a starter or, worse, lurch the bike forward unexpectedly. The seller specifically says this one is wired up correctly and won’t let you start it in gear, which tells you the person who fitted it knew what they were doing. That’s a genuine plus, not just a gimmick. It means you get the convenience of keyless go without sacrificing the safety interlocks Yamaha built into the bike.

What we don’t have here is the mileage, any service history, or the number of previous owners. Those are standard bits of information you’d normally see in a listing, but the seller hasn’t included them. That’s not necessarily a red flag, but it does mean you’ll need to ask. A 2012 125cc bike could have done anything from a few thousand miles to thirty or forty thousand, and that makes a big difference to value and what you should look out for. Similarly, a full service history is worth its weight in gold on a small-capacity sports bike, because these engines work hard and regular oil changes are vital. Don’t be shy about asking for specifics before you commit to a viewing.

Specifications

Anything else – colour, mileage, engine size beyond the obvious 125cc, fuel type (it’s petrol, but not explicitly stated), and transmission (it’s a manual, but not explicitly stated) – hasn’t been provided. We won’t guess. If those details matter to you, put them on your list of questions for the seller.

Why Consider This Vehicle

There are a few solid reasons this particular Yamaha YZF R125 is worth a proper look. First up, the fresh MOT takes a weight off your mind and your wallet. Buying any used bike comes with a bit of uncertainty, but knowing it’s just passed a test means the basics are in order. Second, the keyless start is not a cheap, tacked-on extra. The seller has been specific about it being wired correctly, with the safety interlock that stops it starting in gear, which suggests someone cared enough to do the job properly. Third, the condition is described as basically mint apart from a scratch or two, so it’s clearly been respected. On top of that, the seller is open to offers and willing to discuss delivery, which can make the whole process a lot easier if you’re not local.

This is a learner-legal 125, so it’s ideal if you’re on a CBT or looking for an economical commuter that still looks like a proper sportsbike. It’s not trying to be something it isn’t; it’s a well-kept example of a very popular model. The combination of a recent MOT, a sensible price, and a properly installed convenience feature makes it stand out from the countless other 125s on the market that have been neglected or bodged.

About the Yamaha YZF R125

The Yamaha YZF R125 has been a staple of the UK learner bike scene since it first appeared in 2008. This 2012 model is from the first generation, which ran until 2013, and it was a bit of a game-changer when it launched. Before the R125, most 125cc bikes looked exactly like what they were: small, basic, and a bit uninspiring. Yamaha changed that by styling the R125 to look almost identical to its bigger R6 and R1 siblings. For a new rider, that was a big deal. It meant you could park up at a bike meet on a machine that looked like a proper supersport, even if it only had 15 horsepower.

Underneath the sharp bodywork, the R125 is a liquid-cooled, fuel-injected single-cylinder four-stroke. It’s not a two-stroke screamer, so it’s relatively smooth and easy to live with. The chassis is a proper steel Deltabox frame, which gives it a planted, stable feel that’s unusual in the 125 class. The suspension is decent for what it is, and the brakes – a single disc up front – are more than adequate for the performance on offer. It’s a full-size bike, too, so taller riders don’t feel like they’re on a toy.

What’s the R125 generally known for? A few things. It’s known for holding its value well. Because demand for good-looking 125s is always strong, a clean, well-maintained R125 will always find a buyer. It’s also known for being relatively reliable, provided it’s been serviced properly. These engines rev high and work hard, so neglect is the enemy. Cam chain tensioners can get noisy on higher-mileage examples, and the valve clearances need checking periodically, but that’s true of most small-capacity four-strokes. The riding position is sporty but not extreme, so it’s fine for daily commuting and the occasional longer run. Insurance is generally reasonable for new riders, especially compared to bigger bikes, and fuel economy is excellent – you’ll see 70 to 80 miles per gallon without trying.

One thing to bear in mind is that the first-generation R125, like this one, is now over a decade old. That’s not a problem in itself, but it does mean you need to check for the usual signs of age: corrosion on fasteners, tired suspension, worn brake lines, and perished rubber hoses. The good news is that parts are easy to find, both genuine and aftermarket, and most independent motorcycle garages know these bikes inside out. It’s a safe, popular choice, and there’s a reason you see so many of them still buzzing around British roads.

What to Check Before Buying

Buying a used 125, especially one that’s over ten years old, is all about doing your homework. The seller has been upfront about the bike’s condition, but you should still verify everything for yourself. Here’s a practical checklist of things to look at, ask about, and check before you hand over any cash.

First, get the registration number and run an MOT history check online. This is free to do on the government’s website and takes two minutes. You’ll be able to see every MOT test the bike has had, including the mileage recorded at each test, any advisories, and any failures. This is the single most useful thing you can do before even contacting the seller. It will confirm the mileage is genuine (or at least consistent) and highlight any recurring issues. If the bike has failed an MOT in the past for something like a badly worn chain or a leaking fork seal, that tells you what to look at more closely.

Ask the seller for the V5C logbook. This should be in their name, and the address should match where the bike is kept. If the seller is not the registered keeper, that’s a red flag, and you should ask why. Also ask about the number of previous owners. A bike that’s had six owners in ten years isn’t necessarily a bad bike, but it’s worth knowing. High owner turnover can sometimes indicate a bike that’s been passed around because of niggling problems. On the flip side, a bike that’s been owned by one person for five years and properly looked after is a better bet.

An HPI check is another worthwhile step. It costs a few pounds but it will tell you if the bike has ever been declared an insurance write-off, if there’s outstanding finance on it, or if it’s ever been stolen. It’s a small price to pay for peace of mind, and it’s something many private buyers skip. Don’t skip it.

When you view the bike, take your time. Look at those scratches the seller mentioned. Are they just light marks on the fairing, or are they deeper? Check the panels for signs of a repaint or filler, which could indicate a previous drop or crash. Look at the frame, especially around the headstock and swingarm pivot, for any cracks or bent metal. Check the fork seals for leaks by running your finger along the stanchion – if it comes away oily, the seals are on their way out. Squeeze the front brake lever and check the pads have plenty of material left. Look at the chain and sprockets; if the chain is rusty, tight in some spots and loose in others, or the sprocket teeth are hooked, you’re looking at a replacement soon.

Check the tyres. Look for the manufacture date on the sidewall – it’s a four-digit code, with the first two digits being the week and the last two the year. If the tyres are more than five or six years old, they’re past their best even if they have tread. Also check for any cuts, bulges, or uneven wear.

Since this bike has an aftermarket keyless start, ask the seller how it works. Is there a physical key as a backup? Does the original ignition barrel still function, or has it been bypassed? What happens if the keyless fob battery dies? A well-installed system should have a way to start the bike in an emergency, and the seller should be able to explain it. Also ask if the keyless unit draws power when the bike is parked, because some systems can slowly drain the battery. If the bike has been sitting for a while, that could be an issue.

If possible, start the bike from cold. Don’t let the seller warm it up before you arrive, because a cold start can reveal problems like a weak battery, poor fuelling, or a noisy cam chain. Let it idle and listen for any rattles or knocks. Blip the throttle gently and watch for excessive smoke. Take it for a test ride if you’re insured to do so, or at least ask the seller to ride it up and down the street while you watch and listen. Check that the keyless start works as described and that it won’t start in gear.

Finally, talk about delivery. The seller has said they’re able to deliver, but you’ll want to know the cost, the distance they’re willing to travel, and what condition the bike will be in when it arrives. If you’re buying without seeing it in person, ask for a video of the bike running, a walkaround showing any marks, and a clear agreement on what happens if it turns up not as described. A deposit is normal, but never pay the full amount until you’ve seen the bike.

The seller is open to offers, so don’t be afraid to negotiate, but keep it sensible. A lowball offer on a bike that’s already priced fairly won’t get you far, but a reasonable offer based on the need for new tyres or a minor service might be accepted. Good used 125s don’t hang around long, so if it’s the right bike, be ready to move quickly – just don’t skip the checks.
