About the 1998 Yamaha YZF600R

The Yamaha YZF600R (Thundercat in European markets) is a 599 cc (36.6 cu in) sports bike made by Yamaha from 1996 to 2007. While similar in style to its sibling, the YZF-R6, the 600R maintains some significant differences, including a less aggressive posture, lower revving and higher torque producing motor, and a large 1 piece seat.

With its liquid-cooled, inline 4-cylinder engine; power at the rear wheel was 100.6 hp (75.0 kW) @11,500 rpm, the YZF600R Thundercat is a comfortable and road-minded sports bike. Its comfortable seating position and relatively torquey motor make it suitable for sport touring applications, while the fully adjustable suspension and Sumitomo one-piece brakes (later used on the R1 and R6) also make it a good choice for track racing.
