NANO vs Bikes

I am thinking, if a car can be produced at the cost of 1,00,000 ( thanks TATA ) with 630 CC.. why we can't produce a bike at 500 CC or 300CC at the same price...?

Pulsar 220, Karizma 220, Bullet 350 (thunder bird) even 150 CC Yamaha R1... all are coming with the same price Tag of four wheeler

What will be the cost of manufacturing a Bike, Break up can be for

Engine: Chassis: Tires: Suspension: Gear box: Exhaust: And few Kgs of Steal & alloys ( now a days, LED lights & Digital speedo also have its own cost) how ever Engine & Gear box will consume most of the bucks for its Technology...

Hayabusa, 1300 CC bike cost 12000$ in US ( 5,00,000 approx INR), but similar sport bikes selling her at 40 Lac.... Great Indians..!

Global Auto’s Rock 100cc..! Can any one recall this name.. YES this is a Cheapest 100 CC bike. Guess the rate.. ( Please don't send the result as A or B or C space space to 9595, you won't get any gift )

A) 25,000 B)28,000 c)20,000

you are right, Global Auto offering a 100CC bike at the cost of 20,000INR, which is very much lesser than Hero Honda Dawn, Yamaha Crux, Bajaj Platina and TVS star.. Global Auto doesn't have customers like our Bajaj, Hero honda ( world no 1 in Two wheeler...?) and TVS.. this Rock 100 claiming a millage of 115 KM/PL that's cool

We need to wait......to see the changes to be happen

My question :

If 100 CC can be produced at the cost of 20000 INR, what will be the CC of a Bike if it is in the price tag of NANO? ( I know only CC can't be a cost driver, but still)
Option A: 500 CC
Option B: 400 CC
Option C: 350CC (Bullet doing its best part)
Option D: 100C ( Yamaha will come with good model with advance technology, but with 100CC or less)

Let we meet on the topic of vegetarians, until TATA....(this means bye bye not NANO...)
