Hello everybody, I have bought the Yamaha Fz and my bike no AS 15C 2031 for the last 3 yers. So I have not found any problem of this bike, so I say that if you buy the bike than buy yamaha bike. Looking at the news FZ-S’s Spec sheet we can’t help but feel a bit disappointed . The engine has shrunk to 149cc and power also taken dip by a unit to 13bhp and 12.8nm torque. Yes, the specs do paint a grave picture, but ride the FZ-S a few feet and the reservation about low power are left behind.
