Yamaha YZF-R1

YZF-R1 - State-of-the art race technology

In the winter of 1997, a new force arrived in the one-litre sportsbike world, the Yamaha YZF-R1. It was much more than just another Japanese motorcycle, it was an instant icon; a unique 'no compromise' machine for road riders ready to accept the challenge of the racetrack. A machine, like all other Yamaha R-derivations ever since, that came with racing in its DNA and the spirit of competition living in every component.

The al-new 2007 Yamaha YZF-R1 adds to the continually proven abilities of all previous versions with a host of new features, most a straight-line in evolution from the success of the MotoGP YZR-M1 machine that has delivered Yamaha the world championship in 2004 and 2005. The new R1 benefits from an entirely new cylinder head where four valves-per-cylinder combustion chambers were adopted. This has allowed more upright inlet and exhaust valves positioning, optimizing airflow into and out of 77 x 53.6mm cylinders, and thus helping boost top end power to 180 PS@12,500rpm.

Even then, an extra 9hp is available, thanks to the effect of the redesigned pressurized air intake system that comes into its own at higher speeds. Titanium inlet valves have been adopted, with all the valves in the engine now operated by lightweight VX Alloy.
