I have been using Yamaha Ray Z scooty for more than a year now and it is still running as smoothly as new.
It is a really comfortable scooty with nice pickup power and good design. Seat is neither too big nor too small, its perfectly made comfort in my opinion. I fills petrol of RS. 250 and the tank is almost full and runs more than 100 km. Handling of this scooty is very good and its tyres look awesome and grip on road is great. It has pretty good space beneath the seat( I put helmet and my jacket with some documents). It have a small hook on front side to hang bags.
Furthermore its spare parts are easily available.
I would highly recommend this scooty.
