If it was manufactured in India It would be selling in India for the same price as they're selling for in Thailand right now. There's not enough big bike market in India to justify local manufacturing yet.
Will need some more years,
Was the same in Thailand.
Before Kawasaki (imho the first big bike , made in Thailand, was the ER6 some time ago) stepped forward, everything over 200cc was either imported or Tiger
Imported was twice the price, as in the west.
After that came assembling, with a 1.5 times price, about.
Now you get local made bikes for the western worlds price.
And cheaper, b/c of the low local taxes
Also the world gets a lot of there bikes from Thailand.
Usually, India is a big rising market on it's own. Plus Brics.
There is still a chance, aside some free trade deals with ASEAN, that the manufacturers will see a market and the need of '100% india'
Rising economy will do.
So kick your politicians, the crowd need more money.
To buy the bike for want have or hobby, not for the need of transportation.
