Symone performance - speed/consumption

This is my first ever mototcycle, as I stated before in previous posts, so I've no terms of comparison.

Now what I can say is that I'm very satisfied with it, but... I trully sense that some other maxi-scooter are way better in terms of motor (speed/performance/consumption).

I've been talking to other maxi-scooter owners and they say that their machines spend less gas than mine.
I'm doing 1 deposit (12lts) to make ~280kms which gives more than 4,2lts/100km :(
I know that I'm a heavy guy, and that I don't perform a conservative drive (I speed up downhill a lot) but at this time I really thought that it would have a better consumption... :(

On the way home I always do this big hill on the highway and other 125 scooters always pass me by... all other brands seem to have more "power", even 125 with two people on it :(

Yesterday was the first time EVER I've pass a scooter on the hill... It was a guy bigger that me with an Sym GTS 125 Evo just like my Symone :)

Symone's new Case :)

Bought a new Case for my Symone :)

In the stand where I bought the bike they didn't have the support I wanted, or didn't try enough to satisfy a customer who requested at least 3 times for a solution to mount a case, I even have sent some pics of what I wanted by email but they don't answer mails, so old fashion company :(

The problem is that the official case support is simple UGLY AS HELL... (my opinion)
See a forum thread about it here.

I've seen some Sym's GTS on the road with a support different from those ugly ones, and for my fortune one bike had a sticker of the stand so I searched online and sent them an email at a friday night.
Next morning at 10 they called me on my mobile and gave me all info and prices, in the next Saturday I went there and the assistance was first class.

Get the product. Great assistance. Nice price.
