The Yamaha YP400 Majesty is a fair bit heavier than the 250, but has beefed up suspension and a much more touring biased set of bodywork panels. It's supremely comfortable, good on fuel, but the 125/250 Majesty makes a better commuter than the Yamaha YP400 Majesty and the T-Max makes a better maxi scooter for another £700.

The chassis is excellent and the Yamaha YP400 Majesty can handle twisty roads just as well as many small motorcycles. You will be amazed at how rapidly you can cut through traffic on busy A roads. The Yamaha YP400 Majesty's sheer weight eventually loads up the front end when you push hard however.

The Yamaha YP400 Majesty's single cylinder 395cc unit is really quiet, smooth and pleasant to use, but a mere 34bhp pushing along 197kgs dry (same as the T-Max 500) just isn't enough oomph for the open road - especially when riding two-up.

The Yamaha YP400 Majesty really impresses you with its finish, the way everything fits nicely and the quality of the ride. Yamaha YP400 Majesty engines are renowned for their mile-munching durability. The Yamaha YP400 Majesty is definitely a cut above rivals like the Burgman 400 or Piaggio X9 500.

The Yamaha YP400 Majesty has a two year warranty and there's a useful range of accessories, but an all-rounder bike like a Kawasaki Versys, or CBF600 Honda might do the same commuting/touring job, but offer more of a grin factor at the weekends. Find a Yamaha Majesty 400 for sale

Comprehensive dashboard, loads of storage space, great mirrors, lighting and a grab rail all help make the Yamaha YP400 Majesty a practical way to get around. Optional extras on the Yamaha YP400 Majesty include top case, backrest and heated grips for all year round commuters.

Version: Non ABS

Year: 2010

Best Ease of ride (still not totally used to it as its the first scooter after riding dozens of motorcycles) Jump on and go Fun Good MPG Surprisingly fast Bad Still not used to scooters yet bought it in the bad weather had a few moments so changed the Avon tyres for Michelin city tyres, feel a lot more confident now. Access for servicing is difficult

Ride quality & brakes 4 out of 5

only done a maximum of 70miles in on stint so far and haven't had a pillion as the weathers been bad since I bought her. But I am a scooter convert now never thought I would be after owning 65+ motorcycles .

Engine 4 out of 5

Bit week but not to shabby once it gets going have seen over 90mph ( on a private road)

Reliability & build quality 5 out of 5

No issues as of yet owned her 6 months

Value vs rivals 5 out of 5

So far cheap to insure and tax, paid for it to be serviced before I picked it up so not sure about servicing costs yet.

Equipment 3 out of 5

Not a lot of equipment but good front and rear light make you visible, can store a full face lid under the seat if possible chose Michelin city 3 tyres they give great feedback and inspire confidence even in the wet.

Buying experience: Bought from a dealer in west London via E-bay no issues

5 out of 5 Super Scoot 400 Majesty with Cruiser Additions
11 November 2019 by MagnusCal

Year: 2006

Annual servicing cost: £100

Owned and rode for about 4 years now. Once some initial previous owner neglect was gone over, one of the best bikes in my 50 yr. plus riding history. One of the most comfortable scooters for my 6' 4 " solo riding style. Cheap to insure, bur fast enough for fun.

Ride quality & brakes 5 out of 5

Left handle front, --- right handle rear no foot brake is WAY easier to control and frees up the extra foot for stability in gravel, darn good brakes. Has an emergency brake for hill parking, another super idea for an auto trans. in gravel. I added custom rear shocks that fit my riding style, Hagon brand, UK made, and springs to my weight and riding style, Best Investment overall !!

Engine 5 out of 5

Very reliable, great mileage, very low maintenence, Power drops off a lot, over half -- if both air cleaners are plugged, not as bad a fix as some claim, but do it . Nobody sells a bike (my experience) with all services freshly done, unless the price is higher to cover that last expense.

Reliability & build quality 4 out of 5

OK, here is where most go wrong.. The drive belt and slider shoes have a service life., along with air cleaners. If you redo those as in the manual , and follow basic service -- thats about everything for say 100 thousand miles. The fuel pump is a single must do item. The replacing of that can be done with drive stuff, that's all there for several years at least.. Part of buying a used scoot , none are new unless you by new !!

Value vs rivals 5 out of 5

The drive belt and tranny is not every year, so above costs are averaged for all major services -- and also the few changable items which take maybe an hour or two. If you buy used, the fuel pump is about the only part which is a "check out this" item, or save grief by having previous owner show reciept for shop doing that.. Expected average engine life seems to exceed 150 thou. miles. The motor is bulletproof -- see most Yamaha Ski, or Sea Doos in 400 size all extra reliable by design. Expect a quiet, reliable, economical and safer weather protected ride.

Equipment 5 out of 5

At close to 50 thou. miles, I added a remote tire air sensor for my own information on the road. Cuts air refills under the scoot by an amazing amount, but shows slow leaks before the trip. I added a handlebar fairing ball mount for a cell phone/ navigation feature. Ran a power cord from the battery direct, and plug for maps, radar detector, music etc. Another " best mod" is a solo back rest with pad. Leans back like a secretarys typing chair, all day comfort about like a recliner. A side effect is better stability control wise. Being in contact slows the scooter to big bike cruiser stability, lean forward for racing effect in corners, that and the Hagon shocks make it a superb ride overall.

Buying experience: Bought private party, as above needs all liquids changed fresh so you get to know your new bike. I paid less with knowing I would need to do some work, but it would be fresh and reliable when finished. Now I just ride without worries, "the MAJ " has taken me weherever I desire. The mods I did make it a 60 mph, and 60 mpg cruiser, that's the comfort zone, not top speed. I ride the non freeway roads by choice, sit back and enjoy the small towns and less big rig hassle, safer too.

Terrible experience, bought the scooter for good money last August and it packed up end of December. Took it apart and tested everything (twice), replaced loads of expensive components, but it refused to start or it started and stalled within minutes. My feeble excuse for a scooter has now gone, thank god, and we held a party when it did. Buy a Burgman 400, honestly they can't be any worse. Wouldn't recommend one to anyone, not even people I don't like! Think this is over the top - go buy one, have it go wrong on you like mine, and you'll see.....

Had my Majesty new about 7 weeks ago. On the ride home about 30 miles I began to wonder had I done the right thing because I had pain in the lower back by the time I got home. Since then I have got more used to it altered my riding position slightly and can now go at least an hour with no aches or pains any more. There is good storage under the seat and a couple of smaller ones in the leg shield. The motor seems powerful enough for me and reasonable on fuel as long as the right wrist isn't twisted too violently. Handling is brilliant really confident and safe. The ride is a little harsh and choppy on poor surfaces but fine otherwise. Brakes are superb, powerful with good feel. Weather protection is good although I could do with a slightly taller screen. I think the cost of a new one is on the high side for what it is at the moment but I suspect that this is mainly due to the currency exchange rate.

My first big scoot after owning nearly 30 bikes, its fun, comfy, fairly rapid for a single cylinder, Yamaha's build quality has come on a long way since i last had one back in 1997. It also has masses of storage space, paint finish is good and handles surprisingly well, it does need a bit more go but it makes half decent progress, screen does create lots of buffeting as it blows right on the top of your head, other than that a very enjoyable scoot, nicer than the Burgman 400, oh and the brakes are outstanding.
