Q. Will it be better than CB Hornet - FZS V2?

Definitely the FZS v3 should be your pick over the cb hornet since honda still offers it with an carburetor engine over the fuel injection on offer with the FZ. All other offerings with tyre, design, frame are all one at the same over which the hornet gets CBS on offer. Anyhow the newly launched FZS should your pick over the year old facelift the hornet received to get recognized on the road. Mileage wise again the smooth fuel injected tci engine on the FZS offers a little more than the cdi carbureted engine on the hornet ,but the results could be neglected (maybe differs by 2-3km).My suggestion would be the YAMAHA FZS.

Hornet is 160 cc and FZS is 149 cc. But you cannot use hornet roughly whereas FZS can be used rough enough. If you want to rev hard go for FZS else go for hornet. I like FZS.

The Fz-s v2 is a good bike, and it has a capturing style, ride wise it's perfect for rider and gives you confidence . It's run almost 190 km in single ride and I ride almost 70k km in 2y 9month and it's give me mileage @48-52 , choice is yours . I prefer fzs fi v2.
