Yamaha YZF R1

The Yamaha YZF-R1 bike, launched in 1998, revolutionized the sportbike landscape by successfully combining the awesome power available previously in the true liter class (1,000cc) with the lightweight and responsiveness that a 600-class chassis affords.

Over the years, despite maintaining its distinctive sharp look, the R1 has undergone technical upgradations to keep pace with the times. The 2006 edition features a short-stroke 998cc DOHC, 20-valve, liquid-cooled inline four-cylinder engine that produces a peak power of 175 bhp.

The dual-valve fuel injection system uses motor-driven secondary throttle valves and 32-bit ECU for responsive, instantaneous power delivery. The refurbished Deltabox V frame, revised forks and a 20mm longer swingarm facilitate superb handling in the R1.
