Yamaha YZF-600R6

Yamaha has confirmed the only changes to the 2010 Yamaha R6 are a revised ECU map and a new, longer exhaust can.
The new mapping is claimed to give smoother acceleration – other wise the bike is identical to the 2008/2009 R6.
Yamaha says: “For 2010 the ECU mapping has been revised, which together with a new muffler design makes for a smoother performance curve, giving a feeling of strong and effective acceleration throughout the engine speed range.
“On the road and the race track this better drivability can be appreciated by the rider, and the feeling of smoother mid-range torque enhances the overall riding experience, making the YZF-R6 an even more desirable middleweight supersport."

Full of innovations and technology you won’t find on any other middleweight Supersport.
Track Ready. Street Smart.
The development targets for the 2010 Yamaha R6 are to be the most exciting bike to ride on the track and the most fun sport bike to ride on winding roads. For 2010, the engineers have tweaked the Yamaha R6 to provide more power in the mid range and to reduce noise for improved rider comfort. But don't worry, the high rpm rush that has made the R6 famous is ready when you are. Confidence, agility, performance and most importantly fun.

The Yamaha 2010 R6 is designed to do one thing extremely well: get around a race track in minimal time. It's about a screaming, 15,000rpm-plus fuel-injected four-cylinder engine in a taut chassis that lets it snap from upright to full lean instantly. Oh yeah; it is a great street bike too.

The R6 is a showcase of Yamaha's latest sport bike technologies.

From the YCC-T fly by wire throttle to the MotoGP inspired straight frame design, to Yamaha's exclusive electronically variable intake stacks, the R6 is designed to take super sport riding to a whole new level. For 2010, we have revised the intake and exhaust systems plus re-mapped the ECU for improved power.

Key Features:

The 2009 Daytona 200 winner is back and ready for the street or track.

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.

The YZF-R6 was the first production motorcycle with a fly-by-wire throttle system-for flawless response under all conditions.

YCC-I®, Yamaha Chip Controlled Intake, is used on the R6 to vary intake tract length for excellent cylinder filling and a broader powerband. On the higher-revving R6, its benefits are even more pronounced.

Back torque-limiting slipper-type clutch greatly facilitates braking/downshifting from high speed. Close-ratio 6-speed transmission delivers seamless power and maximum acceleration.

Engine:

Compact, lightweight 67mm x 42.5mm, 599cc DOHC 16-valve, liquid-cooled titanium-valved four-cylinder has a compression ratio of 13.1:1, for great response. Domed pistons with valve cutouts produce a compact combustion chamber.

Fuel injection mapping for the YCC-T-Yamaha Chip Controlled Throttle dual-injector system complements the high compression ratio for great throttle response and reduced engine braking.

YCC-I-Yamaha Chip Controlled Intake electronically varies intake tract length for a broader powerband.

A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization.

Fork height adjustability and rear ride-height adjustment accommodate a great range of riders and tires.

YCC-T uses a powerful ECU and multiple sensors to provide perfect, smooth engine response and optimal power whenever the throttle is twisted under all conditions.

Twin-injector fuel injection: shower-type injectors above each intake funnel help achieve optimum fuel atomization at high rpm.

Slipper-type back torque-limiting clutch greatly facilitates braking and downshifting from high speed. Close-ratio six-speed transmission delivers seamless power and maximum acceleration.

GP-style titanium muffler contributes to mass centralization and contains EXUP® for a broad powerband, and 02 sensor for spot-on injection and emissions compliance.

Linerless, direct-plated ceramic-composite cylinder bores mean greater heat dissipation for consistent power delivery and reduced friction.

Cool magnesium valve and engine covers are light and stylish.

Direct-ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing.

Chassis/Suspension:

Deltabox® aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling.
The lightweight swingarm pivots high in the frame, for increased anti-squat effect and mid-corner stability. TZ-type chain adjusters ease rear tire changes.
Four-way adjustable (preload, high-speed compression, low-speed compression and rebound damping) inverted fork with 41mm tubes increases freedom in setting up for street or track use; soak up the bumps and resist bottoming when braking.
Four-way adjustable (preload, high-speed compression, low speed compression and rebound damping) piggyback rear shock delivers exceptional rear wheel tracking and stability.
Dual 310mm front disc brakes use forged one-piece radial-mount calipers and radial-pump front master cylinder with adjustable lever for astounding braking power and feel.
The casting technique for the five-spoke 17-inch wheels makes the rims light and strong, not to mention wickedly cool-looking.
Removable rear shock spacer and adjustable fork ride height allows the rider to tailor the ride position for the best fit and comfort.

Features and Benefits (Canada)

Engine:

Ultra-compact, lightweight, short stroke, 599cc, DOHC, 16-valve, liquid-cooled, in-line four-cylinder with lightweight titanium valves produces incredible horsepower for a 600cc engine. Redline is set at an amazing 16,000rpm.
67mm bore and 42.5mm stroke provide a fast revving powerplant. Engine width is minimized thanks to Yamaha's special casting technologies and "liner less" cylinder design.
Compact "pent roof" cylinder head design features ultra lightweight titanium valves for both intake and exhaust. The intake valve angle is 11.5 degrees and the exhaust is 12.25 degress. The intake valves are 27mm in diameter while the exhaust valves are 23mm.
Single intake valve springs reduce weight and "friction" for optimum high rpm performance. The valve spring material for both the intake and exhaust has been revised to accomodate the increased power. The valve retainers are made of lightweight aluminum.
High flow intake and exhaust ports allow more fuel in and more exhaust out for great power delivery at all rpms.

Lightweight magnesium cylinder head cover and case covers reduce weight.

Separate cylinder block (the cylinder is no longer part of the upper crankcase) design utilizes ceramic composite plated "liner less" cylinder bores. The ceramic coating is sprayed directly on the aluminum block. The benefits are greater heat dissipation for consistent power delivery, reduced frictional power loss, reduced oil consumption and since there are no heavy liners, reduced weight too.
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.
Lightweight crankshaft features 31mm bearing journals. The inertial crank mass has been optimized for excellent throttle response and impressive acceleration. The crank journal bearings feature new design oil holes that increase the supply of oil.

High lift / high performance, hollow, side-driven camshafts provide arm stretching power and strong acceleration.

Semi-hydraulic type automatic cam chain tensioner reduces mechanical noise and maintenance.

Mikuni fuel injection system with 41mm throttle bodies features twin injectors (primary & secondary). This type of twin injector system is also found on our MotoGP M1 machine. Each of the injectors utilizes 12 spray holes to maximize the atomization process. The secondary injectors, located inside the airbox, begin to function at mid rpms (6,000 to 7,000rpm) thru to redline. This system is lighter and simpler than the sub motor driven secondary valve type FI system. Special short intake tracts allow for higher rpms and improved power.

The F.I. system features separate TPS (throttle position sensor) and APS (accelerator position sensor) sensors.

Yamaha Chip Control Throttle (YCC-T) is another 1st for Yamaha. This system electronically controls the throttle for outstanding response and improved controllability at high rpms. The system features Throttle Position Sensor (TPS) and D.C. motor driven throttle valves. The YCC-T system electronically controls the throttle valves for outstanding response and improved controllability at all rpms. The YCC-T is used to provide even more control of the intake air volume for a smoother torque character. The YCC-T features 3 - ECU's inside the main ECU to control ignition, fuel injection and the YCC-T. This special ECU is capable of responding to changes at a speed of 1000th of a second.

Revised YCC-I or Yamaha's Chip Controlled Intake means the intake funnels / stacks vary in length between 2 pre-set positions depending on engine rpms. The transition rpm is approximately 13,700 rpms. An electronic servo motor varies the funnels. The revolutionary YCC-I provides the best of both worlds …solid low rpm torque and power combined with an amazing high rpm rush. It takes only 0.3 of a second for the funnels to move from the tall to the short position.

Revised funnel / stack diameter has been optimized for improved low and mid range power. The changes will affect the most commonly used rpm range, making the R6 easier and more fun to ride.

Yamaha's exclusive YCC-I electric-control servo motor-driven variable intake funnel system is a world's 1st on a production motorcycle and works in conjunction with Yamaha's fly-by-wire technology and FI systems.

Revised 7.6 litre air box utilizes a viscous paper type air filter. The size of the inlet duct has been optimized for improved mid range power.

Ram Air Induction System with centrally located intake duct delivers cool, high-pressure air "force-fed" into the intake tract for optimal combustion and greater horsepower at higher speeds. This design provides straight induction from the central fairing duct to the airbox without a lot of bends or turns.

Close ratio 6-speed transmission delivers seamless power delivery and maximum acceleration. Gear widths, splines and engagement dogs have been optimized to handle the R6's power. The shift drum and shifting mechanism are located on the right side of the cases for smooth shifting feel under power. The gears use flat contact-type engagement dogs for positive shifting and great durability.

The "Tri-Axis" or stacked transmission design creates a more compact engine front to back that allows for optimum engine placement in the "sweet spot" of the frame for optimized balanced weight distribution and incredible handling.

Slipper or back limiter clutch assembly reduces rear wheel hop when making hard down shifts or under hard braking. Key benefit is reduced lap times and smoother control when participating in either a race or track day. This clutch uses 9 paper based friction plates and 8 steel plates, plus 6 coil-type clutch springs.

The oil lubrication system has been optimized to reduce frictional loses caused by "oil drag". It features a "two side" oil pump. There is a separate liquid-cooled oil cooler to insure consistent engine temperatures for maximum performance and extended service life.

High capacity cooling system features a curved radiator with dual ring-type fans for excellent engine cooling efficiency. The ring-type fan offers more airflow than a conventional type fan.

Direct ignition coils, iridium dual electrode spark plugs and high-output magneto deliver reliable, super strong spark. With this system, the ignition coils are integrated into the plug caps, significantly reducing weight.

Revised "Mid Ship" 4-into-2-into-1 exhaust maximizes engine performance. The header pipe diameter and length have been optimized for improved flow. While the internals of the under engine "muffler box" have been revised. There are three, 3-way honeycomb catalyziers with an oxygen sensor in the system to reduce harmful HC & CO exhaust emissions. The oxygen sensor provides feedback to the ECU so it can adjust for the optimum fuel/air mixture. The "mid ship" MotoGP style, lightweight titanium muffler is located below the engine to central mass and lower the center of gravity for great handling.

The exhaust system also features Yamaha's EXUP System (Exhaust Ultimate Power Valve) utilizing a titanium body and butterfly valves that prevent the "blow back" phenomenon caused by "valve overlap". This design reduces weight and maximizes cornering clearance. The EXUP system eliminates
"flat spots" in the power band and reduces emissions too. This is a 1st on a 600cc supersport machine.

High powered 32 bit electronic control unit actually contains three ECUs inside the main ECU to control the FI system, the YCC-T system and the ignition system. Revised ECU mapping complements the engine modifications.

Air Injection System (AIS) injects fresh air into the exhaust ports to fully burn any unburnt fuel in order to reduce harmful CO & HC exhaust emissions

Chassis/Suspension:

Compact, lightweight aluminum Deltabox frame offers an optimized total 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). The ram air duct passes through the frame at the head pipe for a straight ram air effect too. A mix of revised mold castings and pressed aluminum plates make up the frame. The engine is a fully stressed chassis member allowing for a super-light frame design.

Lightweight, detachable magnesium rear subframe. The detachable design allows rear shock access and is less costly if the unit is "looped out".

Lightweight, aluminum "gull wing" type swingarm uses a mix of castings and pressed plates for optimum rigidity. The swingarm pivot area has been modified for increased rigidity. The swingarm pivot position has also been optimized to reduce the "squat" tendencies caused by drive chain reaction to hard throttle openings.

Key chassis geometry figures include: 1380mm wheelbase, 24 degree caster angle, 97mm of trail and a 52.5% front and 47.5% rear weight balance. The maximum lean angle is a knee scraping 57 degrees.

Fully adjustable 41mm inverted front fork provides 120mm (4.7") of wheel travel and offers incredible suspension performance with ultra-precise feedback. Adjustments include: spring preload, 4-way high speed compression damping, 20-way low speed compression damping and 25-way rebound damping. The inverted design not only reduces unsprung weight but also increases the rigidity of the fork. The range of adjustments allows the rider to tune suspension to match riding style and conditions.

Upper triple clamp features a 30mm offset for precise handing and great steering feel. The lightweight aluminum clip-ons are mounted below the triple clamp.

Fully adjustable Monocross link rear suspension utilizes a piggyback-style shock providing 120mm (4.7") of wheel travel. Shock adjustments include: 9 steps of spring preload adjustability, 20-way high speed compression damping, 4 -way low speed compression damping and 20-way rebound damping adjustability. The piggy back design helps to keep the shock oil cool for more consistent damping.

Radial mount, monoblock, 4-piston calipers squeeze large 310mm dual front discs. The radial mounting design helps to reduce caliper distortion for improved braking performance with excellent control and good lever feedback. The disc carriers are made from aluminium for reduced weight while the sinter metal pads provide incredible stopping power.

Brembo radial pump master cylinder features a 16mm piston. The radial design allows for more powerful braking and improved lever feedback. The lever is adjustable for various hand sizes.

Light weight 220mm rear disc brake is squeezed by a single-piston caliper

Lightweight five-spoke 17" wheels reduce unsprung weight by making hub and spokes a single structural unit. A special casting technique makes the rim section substantially lighter and stronger.

Ultra-sleek "new edge form" bodywork features a sharp front profile with centrally located Ram Air duct, engine-revealing side cowlings and ultra-sleek tail section. There are special side fairing intake ducts to allow cool air to circulate around the engine, fuel tank and frame areas. "Minimalism" and "mass forward" movement are two words that best describe this design body.

17.5-litre fuel tank provides excellent rider ergonomics and an aggressive riding position. The reserve portion of the tank is 3.5 liters. The tank features a front tank cover like the R1 and an internal electric fuel pump.

Separate rider and passenger seats. An optional rear seat cowl is available.

Dual 55 watt H7 "cat eye" headlights. These lights not only cast a bright beam of light, but also feature a sleek profile for superb aerodynamics.

Compact race inspired multi-function digital and analog instrumentation with adjustable back lighting. Features: analog tach, digital speedometer, dual tripmeters, low fuel warning light, fuel tripmeter, and clock. There is also a programmable shift light and stop watch/lap timer that is controlled by the LHS handlebar mounted switch gear.

Single lens LED taillight provides excellent visibility, extended service life and uses less power than conventional bulbs.

Immobilizer ignition system is designed to reduce the possibility of "ride away" theft. This system must recognize the "coded ignition key" in order for the unit to start. If the immobilizer ignition does not recognize the key (or a theft's screwdriver or other type of "jimmy tool") the bike will not start even if the ignition is turned or forced into the on position. If the system does not recognize the correct coded ignition key, the ignition system and starter will not function.
