Super Standard
a Muscle-Sport Motorcycle

Derived from the legendary R1 racing machine, the FZ1 packs a huge amount of horsepower and torque into a chassis that handles like a superbike yet is comfortable enough to ride all day long and fun to cruise around town.  Initially the FZ1 was developed as the Fazer for the European market upon request to satisfy the Euros high-mileage, high performance riders.  Yamaha engineers took the heart of their class-leading liter bike, the R1, and "re-tuned" it for broad band torque and power at all ranges for street and road riding.  A modern Muscle Bike!

A Modern  Muscle Bike right out of the box? Yes.
One bike that can do it all for me? Yes
