No.. Never ..

The new FZ v2.0 Fi brings a very smooth riding experience with itself. The newer version gets a better and refined engine, which produces less paper values than the older version but is really a very frugal unit. It return more mileage than the older one and is really a good ride for both city as well as highway rides. The Yamaha FZ v2.0 comes with a better seat width than the older version, making it more comfortable than before. It has the widest tyres out of all the above listed bikes, making it the most road friendly ride. It just sits back when it comes to wind blast reduction as Bajaj Pulsar offers a windshield which saves the rider from certain level of wind blasts.
