WHAT THE F*CK?
You have clocked JUST 30kms on it and you are already complaining? Bhai thora time diya karo kisi product ko. Your seat's foam will eventually settle down to your weight.
In my opinion, finish the running period. Have some tests runs (like i mentioned before). And if you still don't like it ... then sell it off.
Agar kuch aur lena he hay, to either go for a USED Deluxe or a Brand New Piaggio (yes i said it. kill me)
