You maybe right that the components and specs are not sport bikish, but the fact is that it does not have to be. Average commuting speeds in india hardly exceeds 60 kmph (~40mph). So having a bike with a lot of torque and power does not serve the purpose and is not relevant to most users (in most metro cities, traffic is really jam packed). Having a lighter motorcycle certainly makes it easier to weave through traffic. Motorcycle market in india is mostly commute oriented unlike in other countries where motorcycles are not used for commuting as much (unless areas with heavy traffic would make people use them for commuting).
Also the specs for Tork matches that of a standard 125cc motorcycle in india (for commuting this is what sells more within cities).
Considering all this a 80mm front and a 110mm rear tires are not too far off too. They're obviously chosen keeping these numbers in mind and to keep costs down.
Overall its directed towards a specific market segment and comparing it to a Zero or any other better spec'd motorcycle is like comparing apples and oranges.
Just my 2 cents
