2021-on Yamaha NMAX 125 Review: affordable, frugal and so easy to ride

The NMAX is small, slim and light – just 131kg with a full tank. It’s incredibly nimble on its Dunlop-shod 13-inch wheels, but never feels flighty or unstable. Low-speed balance is excellent, and for threading through traffic it’s hard to imagine anything doing the job any better.

Suspension has been tweaked for 2021. The 30mm forks are still unadjustable, but the rear twin shocks now have a neat, simple, two-step preload adjuster you can turn by hand. Ride quality from the front end is decent, but the back end’s still pretty bouncy at times.

Brakes are a 230mm disc and single-piston caliper at each end of the bike, with ABS as standard. They’re excellent: plenty of power, good bite and reassuring feel – there’s no numbness or grabbiness here.

The 125cc liquid-cooled undersquare single is dubbed Blue Core, and hasn’t been changed massively, but it does have a new cylinder head to help reduce emissions and improve fuel economy.

All four valves are still operated by a single overhead cam, while the NMAX’s elegant and simple variable valve actuation system – which increases inlet valve lift for more power above 6000rpm – is unchanged. Peak output remains 12bhp, giving enough poke to indicate a Yamaha NMAX 125 top speed of 67mph on the LCD speedo.

In a first for Yamaha’s scooters, the NMAX now has a Stop-Start system. This means after a few seconds of sitting stationary just idling on a shut throttle – for example at a red light – the motor turns itself off to avoid wasting fuel.

Then, when the lights turn green, the moment you open the throttle the motor fires straight back into life and off you scoot. Restarting is near-instant and almost silent, thanks to a clever design that does away with a traditional starter motor, instead using the alternator in reverse to spin the crank directly.

Traffic-light drag racers who go on the ‘g’ in green may find just the tiniest fraction of a second delay between twisting the throttle and moving forwards, but if you really don’t like the system and are happy to burn petrol there is a button to turn it off.

The benefit, of course, is that when the engine isn't running you're not using any petrol, so it's great for fuel consumption purposes.

The NMAX also gets traction control for 2021. Yes, really – even with just 12bhp. It’s there for safety (think wet drain covers, diesel spills and gravelly potholes) rather than reducing your laptimes. It’s a fairly basic system and most riders will probably never trouble it – but surely it’s better to have it and not need it than need it and not have it. Especially on a bike with new and novice riders square in its sights.

The motor pulls easily through the CVT drivetrain and never feels strained, even flat out. It’s super-smooth too, with no nasty vibration, in part thanks to new rubber bushes on the engine mounts. Low-speed throttle connection is perfectly intuitive too, making it easy to do walking-pace U-turns.

For a bike costing as little as the NMAX does, its overall sense of fit and finish are impressive. The switchgear feels reassuringly solid, the panels all join together nicely, and nothing is left exposed that shouldn’t be.

Like the previous NMAX it continues to be built in Indonesia, and there’s no reason to think the resulting quality will be any different. MCN readers give the 2015 NMAX a solid four stars out of five for reliability, which bodes very well for the latest model.

If you're in London, or any other urban centre for that matter, and you see a battle-scarred Deliveroo rider the chances are they'll be riding an NMAX or a PCX and as proving grounds go that's about as tough as it gets. If the NMAX can survive thousands of miles of delivery riding often without services and plenty of crashes then they'll survive anything.

Yamaha has packed a lot of features into a small bike boasting a very attractive price tag. Official RRP was £3399 on the road in 2021, or about £50 a month on PCP. Given Yamaha want to sell this to new commuters, many of them moving away from public transport, that’s a very keen price. Running costs should be ultra-cheap too. The 2022 Yamaha NMAX 125 was an entire pound more expensive, at £3400, while by January 2025 the price had shot up to £3600.

Yamaha’s claimed 128mpg fuel economy means £10 of unleaded will easily cover 200 miles. Maintenance should be minimal, though a valve-clearance check every 3500 miles seems a little excessive given the mildly tuned motor. Owners of the previous NMAX report typical annual servicing costs of around £150.

Yamaha openly admit the NMAX’s biggest rival is Honda’s ultra-popular PCX 125, which also has an update for 2021, a similar tech spec and now costs £3169. That’s a tempting £230 saving over the more expensive NMAX.

If you like gadgets, there's a long list of Yamaha NMAX 125 accessories. As well as the new traction control and stop-start, there’s now a convenient keyless ignition system taken from the Xmax 300. Just keep the fob in your pocket, then turn a dial to unlock the steering and switch the bike on.

The NMAX also now comes with basic Bluetooth connectivity. Pair your smartphone and the new LCD dash will inform you when someone’s calling, or you have a new message.

It’s not as complete a system as 'bigger bikes' connectivity setups though – so you can’t also pair a headset, answer or make calls from the bike’s switchgear, nor control music. Using Yamaha’s 'MyRide' app reveals extra trip and tech information too.

A 12-volt lighter-style power socket lives in the open cubbyhole by your left knee. A second closable storage space sits by your right knee, though it’s not lockable. Underseat storage is 23 litres and Yamaha claim you can fit an XL-sized full-face lid.

We’d dispute that – we tried two different helmets (one full-face, one flip-front) and in neither case was the seat even close to shutting. Different sizes and styles of helmet might have more success – but definitely don’t assume your lid will fit without checking first.

There’s a handful of practical options and accessories too, including a tall screen (£132), a 39-litre top box (£292 will all the fittings), plus heated grips and an apron also due but not yet priced. The firm say they'll offer Yamaha NMAX 125 performance parts such as replacement Öhlins shocks with adjustable damping.
