The engine was capable of producing 108 horsepower at 13,500 RPM and had a maximum torque of 59.4 Nm at 11,500 RPM.
The motorcycle featured a steel frame and had a fuel tank capacity of 4.6 gallons. The overall dry weight of the bike was 364 pounds. It had a seat height of 32.3 inches and a wheelbase of 55.5 inches. The front suspension was a 41mm upside-down fork, while the rear suspension was a single shock absorber with adjustable preload and rebound damping.
The R6 was equipped with a dual 320mm front disc brake and a 220mm rear disc brake. The front tire size was 120/60 ZR17 and the rear tire size was 180/55 ZR17. The bike also featured a full-fairing design with a twin-headlight setup.
The R6 was available in various colors such as Team Yamaha Blue/White, Raven, and Yellow/Black. It received several updates and changes throughout its production run until 2002, when the second generation R6 was introduced.
