Introduced in 1998, the Yamaha YZF-R1 is a high-performance street motorcycle in Yamaha's Super Sport line. The YZF R-1 quickly became one of the most popular sport bikes in the industry, despite a world-wide recall for clutch problems in 1998. Though the YZF-R1 went through a series of minor cosmetic changes between 1998 and 2006, there were very few changes to the engine, chassis or other major components.
