Majesty owner here. There was a minor CVT change between the '04-'08 and the '09-'14 models.
I agree with what
sc00ter shared, but there is a third air filter for the CVT fan. All get dirty after about two oil changes. The HiFloFiltro versions are the way to go here, as you can get all three them off Amazon for what one Yamaha-branded filter costs.
Belts last 12.5K and aren't too terrible to replace.
Oil changes involve a filter swap; it uses the same cartridge as an '03-'06 Burgman. Filter is on the left near the drain plug.
I did replace the steering bearings at 15K due to notchiness with an All Balls tapered bearing kit. Well worth using over the mixed stock setup. I replaced the rear dampers with IKON dampers, which also made a big difference in cornering feel.
The Malossi CVT upgrade is pricey out of the gate, but it was well worth it for improving takeoff, top end and surprisingly, fuel economy.
AZScootRN and I did a comparison ride between his minty '13 Maj and my modded '08 and documented it in
The Scooter Zine (Howard, do you recall which issue?). Despite being able to gap him badly off the line and leave him in a 20-80mph roll-on comparison, I could accelerate a little past target speed and roll out more throttle to "overrange" my cruising speed and return a small improvement in average fuel economy.
I have 30K on mine and have been doing some overdue maintenance. Fork seals were worth doing. I used Showa SS8 fork oil to firm up the forks a touch. Replacing the coolant hoses due to age. Parts availability is still good, though some parts have had long lead times since the pandemic. The only iffy bits seem to be body plastics.
The engine is a Minarelli design (Yamaha owned Minarelli from '01-'20) and it is very robust. It needs little beyond routine maintenance and I have little doubt that it could last 100K.
I'm not a maxi guy myself and I passed on a bunch of other scoots, but the Maj turned out to be the right combo of speed, comfort, usable storage, power and range for me.
EDIT:
25BIKEZ brings up a good point with the fuel pump. The CP250 Morphous, YP400 Majesty and the XP500 T MAX all had the same issue with fuel pumps around '08-'09. The problem seemed to impact the T MAX more due to the position of its fuel tank relative to the engine, so the problem is usually called "T MAX Fever" by those who have dealt with it. Essentially, the OEM pump tolerances were a bit tight and when the pump warmed up, it would bind up. You had to wait for the pump and fuel to cool off before the scoot would start again. Having done Quantum fuel pump swaps on all three models, I can say that it's hardest to do on the Maj due to the tank being sandwiched between the upper and lower frames and the pump assembly is tucked under part of the frame, unlike the Morph and T MAX. See if the recall was done to save some heartburn.
