Key Features: Cycle World magazine’s Best Middleweight Streetbike of 2005 was also the 2003 AMA Supersport Champion: this one’s the best of several worlds. Light weight, big horsepower, razor-sharp handling and a surprisingly comfortable cockpit make the R6S an outstanding do-it-all sportbike.
Engine: Ultra-compact, lightweight, 600cc liquid-cooled, DOHC 16-valve inline four-cylinder puts out 123 horsepower. Competition-bred suction-piston-type fuel injection with 38mm throttle bodies features short intake ports and a special vacuum-controlled intake system to ensure instant throttle response all the way up to the 15,500-rpm redline. Direct ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing. Compact slant-block engine design uses stacked gearbox shafts to create a low center of gravity and balanced weight distribution. Ram-Air Induction System delivers cool, high-pressure air for optimal combustion and greater horsepower. Lightweight forged pistons on carburized connecting rods for superb strength and reduced reciprocating mass. Linerless, ceramic-composite cylinder bores mean greater heat dissipation for consistent power delivery and reduced friction. Close-ratio six-speed transmission delivers seamless power and maximum acceleration. Three-axis gearbox design stacks input/output shafts to keep overall engine size to super-compact dimensions. Curved radiator follows the contour of the frame and bodywork for an ultra-sleek look and excellent cooling performance. One-piece cylinder and crankcase assembly provides superior engine rigidity and light weight. Compact, large-capacity clutch delivers consistent, fade-free performance. Large-capacity water pump, liquid-cooled oil cooler and twin ring-type radiator fans ensure optimal engine cooling efficiency. Four-into-two-into-one aluminum exhaust optimizes engine performance, reduces overall weight and tucks in high for maximum lean angle.
2007 Yamaha YZF-R6S
Chassis/Suspension: Light and carefully tuned Deltabox III frame and Controlled Fill swingarm are key to the R6S’s class-leading handling performance and feel. Fully adjustable 43mm fork reinforces R6S’s main strength: precise handling. Forged lower triple clamp also increases rigidity. Fully adjustable (preload, compression and rebound damping) piggyback rear shock with 4.7” of travel delivers exceptional rear wheel tracking and stability. Removable CF die cast rear subframe is light and strong. Super-light five-spoke 17-inch wheels reduce unsprung weight; a special casting technique makes the rim section light, not to mention wickedly cool-looking. Light, 298mm front brake discs, four-piston calipers and radial master cylinder provide unsurpassed braking power and feel.
Additional Features: Durable, lightweight, aluminum clip-on bars provide optimal vibration damping. Narrow 4.5-gallon fuel tank provides excellent rider ergonomics and aggressive seating position. Multi-function digital and analog instrumentation features: programmable shift light, digital speedometer, analog tachometer, dual tripmeters with miles-on-reserve function, odometer, water temp gauge and lights for neutral, high beam, low fuel and turn signals. Dual Gatling beam 60/55-watt multireflector headlight features a sleek profile for superb aerodynamics and visibility. Dual LED taillight design provides excellent visibility and a sleek profile. Standard toolkit located in convenient storage compartment under passenger seat.
