Following the footsteps of the R1, Yamaha introduced the first R6 in 1999. In was a light (429.9 lbs wet weight) and powerful (120 hp at 13,000 rpm) middleweight super sport motorcycle which could do 155.3 mph if you’d dare challenge it. The carbureted 599 cc liquid-cooled, inline four-cylinder; DOHC, 16-valves engine was a real revver, but still managed 68 Nm at 11,500 rpm so the immense potential of this bike was soon spotted by riders who had seen enough of the Honda CBR600F, Kawasaki ZX-6R and Suzuki GSX-R600.

The updated 2001 Yamaha YZF-R6 featured a quick-release number plate hanger and LED taillights. Yamaha didn’t intervene at performance figures so the 2001 model year was just a cooler, but not angrier R6.

But 2003 was the year of changes for the notorious model and the fuel-injection system, swingarm, five-spoke wheels and a revised frame surely suited it well. Still, horsepower and torque didn’t increase with much, but how easy the power was obtained and put on the track was the most important advantage.

In 2006, Yamaha launched an all-new R6 which wasn’t just a race replica, but a true racing bike with headlights, mirrors and street rubber. They aimed towards perfection and the sharp new bike looked like nothing ever seen before. This is when the R6 got the Yamaha Chip Controlled Throttle systems and the 600cc engine’s performance went above the 130 hp psychological limit (131 hp at 14,500 rpm) while torque was still 68 Nm but at 6,930.

The 2008 model year was only left to feature the Yamaha Chip Controlled Intake as a new, cool system and it did, making the Yamaha R6 the most sophisticated middleweight super sport bike out there.
