I want to buy a new bike but I am confused betwen Yamaha FZS V2 and Fazer and Bajaj Pulsar 150.
Yamaha fazer v2.0 is awesome bike, cost wise its expensive compare to others bikes (that you mentioned) but look wise there is no other choice. Technology they used in fazer v2.0 was fuel injection so you get more milage. Finally fazer v2.0 is the best choice to bike
Bajaj Pulsar is good but Yamaha FZ or Fazer is best in terms of looks.
Of course Pulsar is the best bike with best acceleration and best classy look, best grip, best braking, everything its the greatest biker ever I ride a Pulsar 150cc.
All these above bikes come in the 150 cc category, but with a different riding style. If their is no budget issue, you should definitely go for the Yamaha Fazer v2.0. Being a semi faired motorcycle, its design is the best out of all and it comes with all the modern day technologies like fuel injection and looks really massive.
