Please . Review on Tips on Choosing Bike Tyres

I want to buy a bike in coming month of July’12

I want to buy 135 or 150CC bike but due to lots of options available in market its difficult to narrow down my option to one or two. So I need you guys to help me at least narrow down the search between two bikes.

My height is 5’7" and weight is 72Kg and I don’t drive a bike for race or speed . I usually drive at 50-60 km/hr speed. I want the bike for city purpose very rarely I go to highways. I am looking for a bike with a balanced mixture of look, power and millage.

I have shortlisted few . let me know your choices and the reasons behind it.

1. Honda CB Unicorn( Heard alot about its smooth engine, comfort driving and handling my first choice of the below choices but looks is very simple and sober:-()

   
   




2. Yamaha FZ S( No doubt Killer Looks, but I found a pillion seat bit uncomfortable for pillion rider, What about its Engine?)

   
   




3. Suzuki GSR 150( Heard it offer many features which unicorn lacks at the same price of unicorn like digital IP. Does not know about its milleage and handling?)

   
   




4. Pulsar 135 LS( how about this? how is this bike?)

   
   




5. Upcoming Discover 135ST

   
   

Please advice me!

Thanks alot
