Its not a good bike another carburated engine.
Yamaha FZ, comprehensive review [Top Speed/Fuel Efficiency] | Bike Chronicles of India
Clutch/Gearbox and Engine performance: "Gearshift quality one of the best. Performance is adequate for city rides, runs out of steam at high speeds"
Top Speed: 106 Kmph (Speedo Indicated)
The FZ feels best from 0-80 Kmph
Fuel Efficiency: "Disappointing for a 150 cc"
Fuel Efficiency: 30 Kmpl (the figure that I got)
and I read read 30-35 from another biker.
So, if the review in the link is right then I am not going to buy that in anyway but if its launched then will give some competion to Suzuki and Honda and they might release something good, something EFI. Because I am not going to buy a carburator engine anyway.
