2014 Yamaha YZF-R6  Key Features 1 - Light, powerful, and bristling with knowledge gained from years of racing, the YZF-R6 is the most advanced production 600cc motorcycle Yamaha—or anybody else—has ever built. 2 - The YZF-R6 was the first production motorcycle with YCC-T® , Yamaha Chip Controlled Throttle system-for flawless response under all conditions. 3 - YCC-I®, Yamaha Chip Controlled Intake, is used on the R6 to vary intake tract length for excellent cylinder filling and a broader powerband. 4 - Back torque-limiting slipper-type clutch greatly facilitates braking/downshifting from high speed. Close-ratio 6-speed transmission delivers seamless power and maximum acceleration. /// Power Ultra-compact, lightweight, short stroke, 599cc, DOHC, 16-valve, liquid-cooled, in-line four-cylinder engine with lightweight titanium valves produces incredible horsepower. Redline is set at an amazing 16,000rpm. /// Performance Lightweight forged pistons feature thin top rings for great high rpm power. The pistons are secured by lightweight tapered type piston pins. The lightweight design means fast engine response. /// Handling Compact, lightweight aluminum Deltabox frame offers an optimized rigidity balance for incredibly light and agile handling. This frame is a MotoGP inspired innovation that Yamaha calls a "straight frame concept". This means the top spars of the frame lie as close to possible to the frame's torsional axis (the line connecting the head pipe to the swingarm pivot point).
