– 2005 Yamaha FZ1

Motorcyclist Magazine’s ”Best Naked Bike” (Sept. 2003), the FZ1’s heritage can be found in the legendary R1. The 2005 FZ1 packs some serious horsepower and torque into a chassis that handles like a superbike yet is comfortable enough to ride all day long. For the rider who craves sport bike performance but prefers more comfortable ergonomics, the FZ1 is the perfect solution.

Everyday Comfort Coupled with Razor Sharp Handling and Open Class Power

Cycle World Magazine’s “World’s Best Streetbike”
— Oct. 2004

For the rider who likes sportbike performance but prefers more comfortable ergonomics. The FZ1 offers a more traditional upright seating position, yet sacrifices nothing in terms of engine and handling performance.

Sometimes it feels sinful to hide an engine like the R1 derived, 20-valve, Genesis powerplant behind bodywork … hence the FZ1.

Our “naked” bike, though, is fully decked out:

Fully adjustable suspension at both ends
Four-piston monoblock calipers
Light, three-spoke aluminum wheels
Wide, high-performance tires
The same semi-upright ergonomics that make dawn `til dusk rides not just possible but highly enjoyable also provide great leverage when the road turns twisty.

In the end, you can come at it from either direction: practical transportation, or 140-horse sportbike.

Both paths will bring you around, eventually, to the one bike that’s both. FZ1.
