Because once you hear the unique exhaust note of the 2011 YZF-R1, it will become clear that this bike is unlike anything before. The R1 represents a major breakthrough in supersport technology and performance. Make no mistake, the R1’s one-of-a-kind growl will speak to your soul. Professional rider depicted on a closed course.

First pioneered in MotoGP racing with the M1, crossplane technology puts each connecting rod 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. The result? Incredibly smooth, roll-on power delivery out of the corners with outrageous amounts of torque like you’ve never thought possible. It’s like having two engines in one: the low-rpm torquey feel of a twin with the raw, high-rpm power of an inline 4. BODYWORK. THAT WORKS: The R1’s futuristic bodywork does more than add break-awayfrom-the-crowd styling. It has a serious, uncluttered look. The side fairing is smooth for a sleek appearance. And instead of the usual four-bulb headlight design, it has just two projector-type bulbs mounted closer to the nose of the bike. This positions ram air ducts closer in for a more compact, smooth design. And the rounded lenses are totally unique to the supersport industry. THIS CHANGES EVERYTHING: The 2011 R1. More than a bike. It’s a whole other level of technology .and performance. CROSSPLANE CRANK The crossplane crank swings four 78mm forged pistons on fracture-split connecting rods riding 36mm journals 90 degrees apart. TRACTION A swingarm designed to increase traction and feel during acceleration. YCC-I Yamaha Chip Control Intake (YCC-I) varies intake length for the broadest possible powerband. Dual-stage fuel injection mounts an injector above each intake. FOUR-WAY ADJUSTABILITY Adjustable rear shock lets you tune for sharp bumps and sudden elevation changes independently.

As its Daytona 200 victory proves, the 2011 R6 is designed to do one thing very, very well: get around a racetrack, any racetrack, in minimal time. It’s all about a screaming, high rpm plus fuel-injected four-cylinder engine bristling with nearly every advanced trick from the Yamaha book, in a taut, tunable chassis that lets it maneuver from upright to full lean instantly– and carve tight, perfect lines. Oh yeah, there’s one more thing: It’s a great street bike, too. Professional rider depicted on a closed course. 2011 YZF-R6 YCC-I / YCC-T: Yamaha Chip Control Intake (YCC-I) is a variable intakelength system that broadens the powerband and reinforces the R6’s amazing high-rev hit. Yamaha Chip Control Throttle (YCC-T) is an advanced fly-by-wire system that translates your wrist’s commands into seamless, smooth power delivery under all conditions. DUAL-STAGE FUEL INJECTION: A dual-stage injector system feeds 13.1:1 compression ratio combustion chambers for right-now throttle response and an uninterrupted eruption of horsepower. SLIPPER CLUTCH: The R6’s ramp-type slipper clutch greatly reduces engine braking for smooth high-speed corner entries. LIGHTWEIGHT MATERIALS: Magnesium subframe, titanium exhaust, Controlled-Fill die-cast aluminum chassis parts–it adds up to a bike that bends into corners effortlessly, clings to inside lines and shoots itself down the next straight. To learn more about the YZF-R6, go to YAMAHA-MOTOR.COM PREDATORY High-speed air runs straight through the steering head and into the airbox, where air velocity becomes air pressure. Dualstage fuel injection and our exclusive Yamaha Chip Control Throttle deliver a smooth rush of power all the way to redline. MAXIMUM TUNABILITY Both ends of the R6, including its piggyback reservoir rear shock, are adjustable for both high- and low-speed compression damping–the better to deal with both sharp bumps and sudden elevation changes. MAGNESIUM SUBFRAME A cast magnesium subframe is even lighter than aluminum and stronger. YAMAHA CHIP CONTROL INTAKE At lower revs, cylinders like longer intake tracts, so the R6’s funnels move downward.
