This is awesome. Actually people say buy this buy that, but the main moto should be the "Need" , If a person buys a N250 or CBR 250 or 150 or 100cc which bike would he preffer ?? which bike can go well with it's surrounding, which bike is more than enough for use....??? will he need that 100-120-130-140-150kmph+ speed ??

I agree with Somen. I did research about sportbikes for nearly 6 months starting from R15 v2.0, d200, cbr 250, cbr 150, zmr, apache 180 etc etc. Test drove them many times. Went through all the first impressions and ownership threads. Finally settled for CBR 150R. Because 1. My budget was 1.5 lacs. 2. I have a pillion requirement 3. Decent FE 4. My ht is 5.5ft so D200 and p200NS are ruled out as they are of little high seating when i test drove them 5. Decent after sales service and with affordable parts.
In essence, it's the need that drove me and felt that CBR 150R is more than enough for my usage and how many times i will go in 130+ kmph. No regrets till now, CBR 150r seemed to be a very potent machine both in city and highway, good in terms of comfort, FE etc.

+1. Those who think that CBR doesn't have enough for city commuting needs to rethink.
