I Own this bike.
First thing this has the same engine that is put on FZ. Little optimization made it more fuel efficient than FZ.
The Bike feels not too boring like discover. And also not too too sporty like CBR. But the angle of sitting makes u feel you are riding a V.muscular bike.
Over this Yamaha Engine is FAB. I love to listen to the melody of the engine many a times keeping my headphone apart.
Well for first year fuel consumption was a bit concern for me. But it has improved as the engine has developed.
Its is like me Horse of the long run. But just maintain it time to time. Believe its is your girlfriend. And believe me this girlfriend dont demands a lot of maintenance. Accessories of this bike are quiet cheap so no worries of that too.
You can choose this if you want a real hero bike and you dont want to spend lots of bucks on maintenance and fuel.
