The Yamaha R6, the first 600cc class motorcycle to come from the dealership with over 100 horse power, was way ahead of its time when it debuted in 1999. With its 599.8cc engine pushing out a monstrous 119.1 horse power dead stock, the YZFR6 became immediately popular with race enthusiasts and amateur riders alike. Even though it was such an incredible bike when it was first released, Yamaha made improvements almost every year to keep this beautiful bike on the cutting edge of the sport bike industry.
