Which one should I buy - TVS Apache RTR 160 Hyper Edge, Bajaj Pulsar 150 or Yamaha FZS V2.0?

The best one out of the above would be the Yamaha FZS v2.0, which uses the most advanced technologies out of all the above bikes and also has the most comfortable ride in the segment. It comes with a 149.5 cc engine, which has been downgraded from the earlier version, uses fuel injection and comes with the widest tires in the segment. Overall its the best option from all the above bikes.

Quick Facst - Yamaha FZS Version 2.0

For stunt and rough riding you should go for Pulsar 150 otherwise it's Apache 160 for decent biking.
