Presently I am riding a 100cc bike Bajaj Platina

Hi,
Presently I am riding a 100cc bike Bajaj Platina. All good but I really want some more power and some more thrust. My brother rides a Pulsar 150cc. I like the bike but want something different. I am more interested in CBZ -xtreme. I like its looks , comfort and technical specification. Also there is Apache 150cc and Honda Unicorn with its new looks. Can someone please advice me as to what is the performance of these Bikes. I am really looking forward for some valuable information
