Huh.......
I'm very happy with mine thanks....
With regard to economy, I put between £5 & £8 of petrol in it every now and again, the amount is so trivial as to be not worth actually working out the mpg figure.....!
The mirrors ( with R & G extenders) mean I can actually see behind me, unlike a Forza (

)
And it comes with an integral rear rack for the top box......
And last time I looked ( this morning !), it appears to be more powerful than an Xmax or a Forza.
And I like the look of it, and people often admire it when I am out on it, which is strange to me as I am a biker really....!
