Hi ! I want to buy a scooter for myself in a price range of Rs. 45,000. I don't want to buy Honda activa and access because these are very common scooters. So, suggest me some unique vehicle.

You have not mentioned that you want a gearless scooter or geared.. though there are very limited options for Geared but for gearless we have many.
From all those I would Suggest Suzuki Access over others. Buy it and you won't regret !
