I just bought Activa 3G and I must tell you that its fuel consumption is 40-50 and comfort is ok not very good as compared to previous versions(the old activa with metal body). Shockers are very poor especially if you ride on a bumpy road. On plain rods its good. Looks is better than previous version. I did not like the combi brake option. The brakes of previous version(old activa) is quite good.
Maintenace is quite high as compared to other scooters of rival companies like Hero Honda.
I must say you should rather buy a bike than activa if you want comfort.
