Wait a minute! A 160 mph top speed, half fairing and modern styling? How can this bike be categorized as a retro or a naked? Good point. As with many of Yamaha's bikes, the FZ1 actually redefines the genre. It's not a standard, or a naked, or even a retro. The FZ1 is a roadster, it's got a big engine, an upright seating position, and it comes with modern styling, loads of power. The result is simple - it's great fun to ride.
