70 US mpg is 3.4 l/100 km.
Lowest consumption I've recorded on mine is around 3.8 l/100 km or 62 US mpg. This is in the summer.
In the winter it is usually 4.4 l/100 km or 54 US mpg.
Here is what's not to like:
- metal parts made of low quality and prone to rusting
Same can probably said about a lot of scooters. I just got my 2007 used from a local rental fleet. It had 3400 miles on it at time of purchase. So far, no rust. The real test will be when I take it to Assateague Island for our annual week at the beach, where it will get exposed to the salt air. Which specific parts have rusted for you (maybe I'll coat them in petroleum jelly before the trip -- I've done that with steel parts on my bicycles).
I guess I'm not expecting the same quality out of a scooter that retailed for $4399 as compared with my Moto Guzzi that retailed for around $8,000. I only paid $1600 for it, so my expectations might not be as high as yours.
- front wheel tends to lock easily
I'll keep this in mind.
- widens trajectory when heavily cornering and exiting the curve
Explain?
- rear suspension bottoms out easily with 120+ kg of passenger weight
I weigh 81 kg, and haven't carried a passenger yet. I do find the ride to be a little harsh, as compared to my Moto Guzzi.
- not easily accessible maintenance (change of brake fluid = few hours, change of coolant = almost a day ; when you do it first time)
This is definitely an area where (naked) motorcycles are much better. You don't have a lot of plastic shtuff to remove to get at the mechanical bits. I'm actually considering just paying the local dealer to do a full fluid change and valve adjustment to avoid the annoyance of having to remove all the plastic bits. They quoted me like $150 for the whole service. I'm thinking it might be worth it. Plus, I get the added benefit of establishing a relationship with the dealer.
Since I have a motorcycle too, I plan on using the scoot for mostly shorter trips, like local errands, and also as an alternative means of transport to our nearly 8000# truck when on camping trips (truck used to pull 34' travel trailer). So, mileage-based maintenance is reduced this way. Longer rides will be on my motorcycle anyway. One disappointing thing about the PS250 is the lack of on oil filter, which necessitates much more frequent oil changes (1200 miles, vs. 6000 for my motorcycle). Heck, even the 175cc engine in the Yager has an oil filter. I guess the flip side of that I don't have to buy oil filters. I have read that oil filters for the P300GTi are like $30. Each oil change only costs me $8 in oil, and no money for labor, just the 15 minutes or so to change it.
- spare parts can be bought only from Kymco and extremely expensive
And this is different from any other make/model of scooter (or motorcycle for that matter)?
In summary, all your complaints about the Kymco apply to just about every other brand. I was also shopping scooters from the Piaggio family (Vespa/Piaggio/Aprilia). A used equivalent from any of them would have been double the money, and parts availability can be an issue. And, from everything I've read, the PS250 is very much an equivalent from a performance and quality standpoint as the BV250, or Scaraboe 250.
I see you have both a PS250, and an Agility 125. Which one is the source of most of your complaints? The Agility 125 is made in mainland China, and the PS250 in Taiwan. The retail price of the Agility 125 is also less than half the PS250, so I would expect the quality of it to be lower.
