The Yamaha FZ1 is not suitable for riders of all experience levels, particularly beginners, due to its high power output of 150 PS @ 11,000 rpm and 106 Nm of torque @ 8,000 rpm, which demands advanced riding skills. The bike's aggressive riding position, lack of ABS in some models, and the potential for throttle snatch in earlier versions make it more appropriate for experienced riders who can handle its powerful and responsive nature.
