I can understand why small displacement bikes tend to not get as much notice compared to countries like India.THIS
Sadly, small displacement bikes in North America are seen as either toys or girly bikes. I hope the recent influx of smaller bikes can change the stereotype, but I wouldn't bet on it.
North America is a lot bigger and sprawled out which requires bigger bikes if you want to travel. Whereas India is smaller and densely populated which requires a smaller bike for maneuverability .
The Grom is a lot more limited when it comes to travel.
