Yamaha have updated the A2 licence friendly XMAX 400 for 2018.

It has improved handling to make it more agile and responsive around town, while being comfortable on longer journeys. It has the same quality feel and similar performance to it’s big brother, the TMAX, for a fraction of the price.

Ride quality & brakes

Next up: Engine

The wheelbase has been shortened to make it 50mm shorter than its nearest rival, the Suzuki Burgman 400. Combine this with 15-inch wheels and the Yamaha is agile and manoeuvrable around town.

Fitted with quality Michelin City Grip tyres and traction control. The twin shocks have five step pre-load adjustment.

Handlebars are two-way adjustable, with two fixed positions, 20mm apart. The screen is also manually adjustable and can be fixed in two positions, 50mm apart.

Twin front brake discs and twin piston calipers are powerful, without being grabby and ABS is fitted as standard. There is a handy parking brake, a must when parking big scoots on an incline.


Next up: Reliability

The 33bhp engine is Euro4 friendly. It’s responsive and smooth in city traffic and on open roads it doesn’t get left behind and has enough punch for higher speed overtakes.

Next up: Value

Yamaha’s MAX range has been around since 2001 and there are no known major issues with reliability.

The XMAX 400 is almost half the price of the TMAX but has the same quality feel and attention to detail. There are nice touches, such as the metal decal on the seat, that gives the scooter a touch of class.

Service intervals are every 6000 miles or 12 monthly, other scooters in this class need servicing more frequently.

We averaged 65mpg during our test, which means the tank range is around 185 miles. The XMAX's main rival is the Suzuki Burgman 400.


Yamaha have fitted an immobiliser and it has keyless ignition, used in conjunction with a dial on the centre console, operates ignition, steering lock and access to the storage compartments. An alarm sounds if you leave the bike unattended without switching it off, annoying but useful.

Storage space is practical and sizeable. The lit under-seat compartment holds two full faced helmets and there are two glove boxes, one of which is lockable and houses a 12v charging point.

A combination of analogue dials and LCD dash are clear and easy to read. With a quick flick of a switch, you can scroll through the display to reveal useful information, which includes MPG.

MCN Fleet: Can the XMAX 400 cope with motorway miles?

Until last month, the KTM’s 125 Duke was my main mode of transport. It was lovely, but after I passed my test, the urge for more power took over. And to be honest I needed it – my 62-mile round trip commute is mostly on motorways and the KTM struggled to sustain 70mph. But Yamaha’s XMAX 400 offers e

Great scooter - an incredible commuter for all weather conditions. Ridden in the rain, and high winds you always feel safe. Very comfortable, quick (if modified), and friendly. Not many of them around (2018 model) and because of that they are quite desirable and hold prices firmly. Very practical - to the point that I've sold my other bike Bandit 1250.

Ride quality & brakes 4 out of 5

The brakes are great, much better than in most of my bikes (last three - Blackbird, VStrom, Bandit). Ride quality - ok when the road is in good nick, but if it's bumpy, the rear suspension isn't doing a great job carrying my 250 pounds... Great wind protection when the windscreen is in the top position - I'm 6'3 so handlebars also need to be moved forward.

Engine 5 out of 5

This is a bloody gem. Vibey and heavy but solid as a rock. Old technology used in boats, snowmobiles, and quads change the oil every 5k kilometers and it will run forever (70k miles are normal in some Majesty 400, Xmax predecessor ). In the 2018 model, Yamaha for some reason used 19 grams weights in variator and that's ok if most of the time you are spent on national roads. If it's a 50/50 town/ open road, do yourself a favor and use lighter weights - you will unleash the beast. With 17 grams Xmax 400 accelerates almost like TMax up to 100 km/h. The economy is almost the same, roughly 60 mpg (4l /100km) In my case best results were achieved by mixing 4 x 16 grams sliders with the original 4x19 grams rollers .

Reliability & build quality 4 out of 5

Quality is there but not quite there if you know what I mean. It is most certainly not an old Japanese school of building things - apparently, it's French and you can see it. Overall build quality is good but small details like fasteners and screws are made of bizarre material that deteriorates quite fast - if you are removing something, do it slowly and with patience (pay attention when removing plactic variator cover - screws with rubber on them are crazy hard to undo). Or get yourself a set of new screws and plastic fasteners from Yamaha. After 5000 kilometers steering head bearing was gone (warranty cover), the rear suspension is ridiculously weak and plastics are prone to scratches. The paint on the swingarm is peeling off at 20k kilometers. The handbrake caliper was rebuilt. The rear disc was warped and the pads were almost gone. Luckily enough most of the things were covered by warranty and small things are very easily repairable if you want to do it yourself. On the plus side variator, rollers after 20k km look almost brand new. So were front rotors and pads.

Value vs rivals 5 out of 5

Parts are not that expensive. Running costs - I'm getting roughly 300 km from one tank of petrol (13l). Not too bad. Oil change would cost around 25 quid.

Equipment 5 out of 5

All bells and whistles from Yamaha - heated grips, ABS, TCS, LED lights.

Buying experience: Bought it used from the dealer after a big service with a warranty. Happy so far...

Version: Phantom Blue (the best colour)

Year: 2018

Annual servicing cost: £250

Worst features: The weight, the weight and the MPG. For a scrawny guy like me, 210kg is a lot to push around. I did my Mod 1 & Mod 2 on this bike (clutch control was a problem for me so went for A2 auto and needed to buy for tests) and I needed a breather after manual handling. The engine is fairly old tech, a bit vibey at times, and noticeably thirstier than alternatives- pushed hard, 60-65 mpg. Best features: Pretty much everything else, really. Looks great, handles well, brakes are superb. Acceleration is brisk, no problems joining motorways or getting up to speed going from a 30 to national limit, say. Motorway stretch on my commute currently limited to 50 mph for the most part and I'm getting 80 mpg. At 50-70 mph it's planted and controlled even in high winds. Underseat storage is huge, and lit. It'll only take one helmet of my size, but that still leaves a lot of room.

Ride quality & brakes 5 out of 5

Despite weight and size, nippy. I haven't been on any long runs yet, but I've found the seat comfy enough so far. I had the factory option tall screen fitted, and it makes for a very calm riding experience. Epic touring would not be a problem for this bike or its rider(s) given its comfort, range and carrying capacity. Brakes are superb, powerful and easily modulated.

Engine 4 out of 5

Engine could be a bit smoother, but the vibration is noticeable rather than annoying. Otherwise, all pretty good. Easy to pull away and pootle along in slow traffic, and when required equally easy to get up to speed. Relaxed at motorway speeds with power in reserve. Overtaking is not a problem.

Reliability & build quality 4 out of 5

Some light corrosion on exhaust and certain fastenings, but cosmetic stuff only, and it's not had any ACF-50 or similar treatments- I'm planning to get that done professionally, when that's practical. Otherwise, no problems so far, only just passed 2,000 miles.

Value vs rivals 3 out of 5

Bit early to tell, yet to hit first major service, but not anticipating any issues. At least for the time being, fuel consumption better than expected thanks to speed restrictions.

Equipment 5 out of 5

Don't mind the keyless system, soon got the hang of it, though the main switch is hard to use in the dark until you've got used to which position does what. The two glove boxes are a decent size. Michelin City Grip tyres excellent. Screen choice seems highly dependent on rider size and seating position. Happy I went for the big screen, though looking through it (and I'm 5 ft 11) rather than over it is somewhat disconcerting. Will go for heated grips at some point. Front lights could be better, high beam doesn't really do much, my Honda PCX is better in this respect. Rear lights are excellent though.

Buying experience: Bought from the Yamaha main dealer in Southampton, Park Road Powerbikes, second-hand. Excellent experience, nice people to deal with.

5 out of 5 5000km review

Year: 2018

The best part is the high riding position which is comfortable even for touring. The worst parts are mirrors supports that need to be taller and wider out. Overall, I'm very pleased.

Ride quality & brakes 5 out of 5

We (the girlfriend and I) did an 800km two-day tour in Northern Spain through hills, mountains, back roads and motorways. Flawless performance and extremely comfortable. Feels like a larger touring bike even with two bags on board spending 5 hours a day riding. City riding is good at great visibility with a high seat.

Engine 5 out of 5

Great highway performance and passing power with passenger and bags uphill.

Great Mileage for a 400cc.

Equipment 5 out of 5

Adjustable handlebars and adjustable windshield made a huge difference.

Buying experience: Good.

4 out of 5 A strong contender in the scooter market, but build quality is potentially an issue
01 October 2018 by Peter Connell

Year: 2018

Rides well, strong engine, good storage, decent weather protection, and big enough for two up riding. Downsides are Yamaha's build quality, which is not the best, and the dealer support which could be better. Dual rear shocks are fiddly to adjust and old fashioned when compared to other manufacturers who have moved to a mono shock on their new models.

Ride quality & brakes 5 out of 5

Strong engine, good brakes, good handling, manoeuvrable, fits rider with added pillion without compromising rider control. Seat is wide but hard, and uncomfortable after one hour.

Engine 5 out of 5

Strong engine. Power delivery is good for overtaking and motorway driving. Throttle response is good making the scooter easy to ride around town.

Reliability & build quality 3 out of 5

Bike failed at point of delivery as ABS unit was faulty and it took two weeks to fix. Issues with rear suspension fixed under warranty.

Value vs rivals 4 out of 5

Only 1,000 mile service at present which is not sufficient to comment on longer term running costs. However, the initial service cost experience indicates that it will not be any cheaper than a standard motorcycle to run.

Equipment 4 out of 5

Bike as standard is adequate, with good under seat storage, but needs the addition of heated grips and the battery charger connector in the non lockable glove box as the battery is behind the windscreen and not easily accessible for charging. Standard windscreen size is fine for people up to 5ft 11. The comfort seat is an option to be considered as standard seat gets uncomfortable after one hour. Optional leg cover is expensive and can only be fitted and removed by a dealer. Top box with backrest is recommended as it adds additional storage that is welcome on a longer trip.

Buying experience: Buying experience at the dealer was good, but the bike was nor properly prepared before collection.
