The 600cc sportbikes have always been the biggest sellers for the big four Japanese manufacturers. Not only are they less expensive than the larger displacement bikes, they are also cheaper to insure, maintain and even though they don't have the same horsepower or torque as the 750cc or 1000cc bikes, they are plenty fast. During the '90s, the 600s were cranking out 85-90 horsepower and running very low 11-second quarter mile times. With top speeds in the mid-150 mph range and a 0-60 mph time of 3.2 seconds, the Honda CBR600 was the dominant bike in the middleweight class. It is estimated that Honda sold over 50,000 600cc bikes from 1987-1993, making it the most popular-and arguably the most influential-600cc sportbike ever made.
