i want to purchase a 100 cc bike preferably hero honda kindly suggest me with price wise . i m resedent of kanpur

What is you budget ?

40000 to 50000

In that budget, from Hero Honda we don't have good choice. Though you can go for splender NXG cost around Rs. 48000 ex-showroom or Glamour or Passion Plus Pro.
But as per my view , all of the above Hero Honda Bikes are dated and are not good as compared to other bikes in same segment from other manufactures.

Around Rs. 52k you can get Honda CBF STunner if you are looking for fancy bike and also from TVS there is Flame but both 125 cc.

From Yamaha you have choice of Alba(106cc) for Rs. 44K and then Gladiator(125cc) for Rs. 49K.

Suzuki also offers some good stuff, you can go for Suzuki Zeus Disc-Self start for Rs. 48K, though they have Access 125cc for just Rs. 39K

Lastly, Bajaj's latest offering is Bajaj Platina 125 DTSi which cost something Rs. 39K and XCD 125 for Rs. 45K .

So now you decide..
Are you looking for some cool looks bike or Just value for money bike ?
Or can you go for 125cc which will add little more power!
