A factor you should consider is as to how well does the respective service centre take care of their customers. I'd suggest you talk to few owners of these scooters. Front disk brake is preferable to a drum. Tubeless tyres are better. The actual mileage claimed by a few manufacturers is many a times way lower than what is claimed. If you are located in the coastal part of India, I would suggest you avoid chrome accessories as they tend to rust (eg. Piaggio Vespa) quickly. LML Star Euro 150 for example comes with a spare wheel.
