From its unique Formula 1 inspired styling to its incredibly
responsive 16,000 rpm titanium valved powerplant, the R6 has been the talk
of the supersport world. And it did not disappoint. the R6 has proven
to be the machine of choice for those riders and racers who will not accept
compromises. Why settle for less?
FEATURES:
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 pure sport bike. 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.
Cylinder head design features ultra lightweight titanium valves for
both intake and exhaust. The compression ratio is 12.8:1, while the intake
valve angle is 11.5 degrees and the exhaust is 12.25 degrees. 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 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 head 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 sits 3mm higher in the cases than "regular" R6S.
High lift / high performance, hollow, side-driven camshafts provide arm
stretching power and strong acceleration. Both valve lift, duration and
timing have been optimized for class leading power output.
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. 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.
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.
7.6 liter air box uses a viscous type air filter.
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 increased 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 increased 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.
4-into-2-into-1 exhaust maximizes engine performance. 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. A "mid ship"
MotoGP style, lightweight titanium muffler is located below the engine to
central mass and lower the center of gravity. The system also features an
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.
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.
Semi-hydraulic type cam chain tensioner reduces tune-up costs /as well
as reducing engine mechanical noise.
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
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). The ram air duct passes through the frame at the head pipe for
a straight ram air effect too. A mix of 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.
Detachable C.F. (controlled filling) die cast aluminum rear subframe
reduces weight and provides easier rear shock access and a less costly
repair if the unit is "looped out".
Lightweight, aluminum "gull wing" type swingarm uses a mix of castings
and pressed plates for optimum rigidity. 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. Adjustments
include: spring preload, 16-way high speed compression damping, 24-way low
speed compression damping and 18-way rebound damping. The piggy back design
helps to keep the shock oil cool for more consistent damping.
Trick, 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 aluminum 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 new 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.
Durable, lightweight, aluminum clip-on bars provide optimal vibration
damping.
Adjustable front brake lever
Special 525 lightweight O-ring chain is used to reduce weight
Steering lock
Lightweight aluminum side stand and chain adjusters
