Hehe! Jealous shouldn't be the case. If you really want a single vehicle for crowded city driving, commuting but also long journeys, this XMAX 300 is a very good investment. You can sell your other scooter and motorcycle

The price is high for a scooter, but think of it as both scooter and touring bike and you will see the point.
I will not point out specs and things that you can see in the brochure. I will try to focus just on my subjective opinion and experience.
Before I bought mine I tested another unit. Just from the first twist of the wrist I could see it is smoother than the PCX 150, even if the power was much bigger (30hp vs 13hp). The engagement of the belt is very linear and sooner than the PCX, so you can take off gently with very few rpms. The top speed with the test unit was 142km/h and the average fuel consumption was 3.5 l/100km (being a test unit it was ridden hard by everyone).
Almost 1 month ago I bought mine. I wanted the brown/bronze one but would not wait 2-3 months for the delivery since the demand is so high, so I settled for the matte grey, which came in 5 days.
As with any new scooter, you have to be gentle during the break-in period. The manual says not over 4500rpm the first 1000 km, and 5500rpm until 1500km. Average fuel economy for the first 1000km was 2.6l/100km, with an average speed of 44km/h. The speed was max 60km/h for the first 500km and then 80-90 until now. I have passed the indicated 4500rpm, but gently only sometimes, to avoid continuous driving at the same speed. Average fuel economy raised to 2.8 l/100km globally after starting going to work everyday in busy city traffic. City only is more like 3 l/100km. Steady riding at 90km/h indicates 2.5-2.6 l/100km.
I have not tested max speed or pushing mine hard yet, I am at 1340km now.
Ride confort is way better than the PCX. I set my rear shocks to most soft position, I think 1/7 and it is very comfortable. From the factory it came with 3/7 and it was a bit harsh on small bumps.
The XMAX 300 is very heavy compared to the PCX150 on paper (179kg), but you really don't feel it. The weight is very low and you only feel it when you try to move it around on foot. The wheels are bigger and wider so it drives more like a touring bike than a scooter. The weight is a plus on the open road when it's windy and trucks come towards you at speed. The wind gust hits you but the scooter does not move (the PCX did move a bit).
The storage on the XMAX is amazing compared to the PCX150, not considering possible top cases. It's 50l under the seat and it really fits 2 medium full helmets plus a small bag. There is even an LED in the trunk. The front 2 spaces are about the same as the PCX, but the locking one has also 12v outlet. I chose this vs Forza 300 for this main reason, the Forza has way less space, you can only fit one small full helmet.
Seat comfort with the stock seat is better than the 2103 PCX150, but it's not amazing. You are fine for 1 hour of riding, after that you should take a small break or you butt will begin to hurt a bit. There is an option for comfort seat that should remedy this.
The wind protection is more than adequate for a scooter, it is comparable with a touring motorcycle. The windscreen is tall and has 2 positions, and the small plastic things that hand out at the bottom of the screen are not for design, they actually deflect some wind of the handlebars. I did not believe this but I tested at 90km/h, moving your hand 5cm above or below the handlebars and you will feel the wind force.
There is no heated grips option, but there is an OEM package available. Also the is a very nice Akra exhaus, but this is 500+ euros.
Another thing to note are the lights. It's almost full LED, and the light is amazing at night. No comparison to the PCX. You are also seen very well from all angles. Even during the day I get more cars to move over and let me split lanes that I even got with the PCX.
At 1000km I also did the first inspection and the dealer changed the engine oil, transmission oil, checked all filters and fluids, breaks, shocks, tires etc, and everything was about 30 euros. Next one is at 4000, and then every 5000.
As a conclusion I am happy with my purchase, no remorse. It's expensive but there is a good reason for this and I think it is worth it.
