Introducing an all-new 847cc
liquid-cooled, in-line 3-cylinder, DOHC, 12-valve
engine with fuel injection.
This engine combines
advanced high tech components including YCC-T and
Yamaha D-Mode, with a crossplane concept crankshaft
to deliver an exciting, torquey and quick-revving
3-cylinder engine features Yamaha’s “Crossplane
Crankshaft Concept” that provides linear torque
development in response to the rider’s throttle
input. Among the advantages of the in-line
3-cylinder engine are: (1) linear torque
development, (2) even firing intervals that provide
smooth torque characteristics and a good feeling of
power in the low to mid rpm range, (3) a light, slim
and compact design, and (4) performance that
combines the characteristics of both 2-cylinder and
reduce vibration and deliver a smoother ride, the
engine has a primary coupled-force balancer that
revolves in the opposite direction and at the same
speed as the crankshaft.
A new 6-speed transmission
has also been adopted to match the new engine. The
transmission has optimized gear ratios that help to
deliver engine torque efficiently. The result is a
transmission that helps bring out more of the low-
to mid-speed torque and excellent response
ride-by-wire Yamaha Chip Controlled Throttle (YCC-T)
system senses the slightest throttle input by the
rider, relays the data to the ECU, which
instantaneously calculates the ideal throttle valve
opening based on engine rpm and throttle opening,
and then sends commands to a servo-motor actuator
that moves the throttle valve which actively
controls the intake airflow volume. This is a
technology contributing to the rider’s feeling of
torque and controllability from the new 3-cylinder
injection has been adopted to provide outstanding
drivability. 12-hole injectors attached directly to
the cylinder head deliver a highly pressurized spray
of atomized fuel with droplets as small as a few
microns. This enables high-precision injection
directed at the valve skirts that contributes to
optimum fuel combustion resulting in outstanding
drivability and performance.
The FZ-09 is equipped with
Yamaha D-MODE (or “Drive Mode”) variable throttle
control system to allow the rider to choose the
optimum engine character for their riding situation.
The rider can choose at will from three throttle
valve control maps (Standard Mode, “A” Mode, and “B”
Mode) for different performance characteristics.
Operation is performed by a button on the
handlebars. STD Mode is set to accommodate a wide
range of riding conditions. In this mode the rider
can enjoy the 3-cylinder engine’s linear torque
feeling from low speeds all the way up to high
speeds. A Mode lets the rider enjoy sharper throttle
response in the low-to mid-rpm range than the STD
Mode. B Mode lets the rider enjoy milder throttle
response than the STD Mode for more relaxed power
liquid-cooled, 847cc, 4-stroke, in-line 3-cylinder,
DOHC, 4-valve engine with downdraft intake and fuel
injection is all new. With a 78 x 59.1mm bore x
stroke and 11.5:1 compression ratio, it produces an
exciting, torquey and quick-revving engine
Some of the
advantages of the 3-cylinder engine in the FZ-09
include linear torque development due to the even
firing intervals that provide smooth torque
characteristics and a good feeling of power up into
the low to mid rpm range, as well as combining
desirable characteristics of both 2-cylinder and
4-cylinder engines. In addition, the engine design
can be light, slim and compact.
To reduce vibration and help
give a smoother ride, the engine has a primary
coupled-force balancer that revolves in the opposite
direction and at the same speed as the crankshaft.
The connecting rods are made
using the fracture split (FS) method to ensure a
high degree of circular precision in the rod’s
big-end ring for a precise fit and smoother crank
revolution. The fracture split (FS) method is where
the big-end ring of a forged connecting rod is split
in two by applying a sharp impact. This creates a
perfectly matching split surface that naturally
produces a much more precise mating surface when
they are bolted together again around the
both exciting and quick revving torque
characteristics and a unique intake sound, the
3-cylinder intake funnels have been designed with
uneven lengths. The first cylinder funnel is
102.8mm, the second 82.8mm and the third is 122.8mm.
This combines with the effects of the YCC-T system
to contribute to an excellent torquey engine
transmission takes full advantage of the
low-to-mid-range torque and excellent response
characteristics of this in-line, 3-cylinder
fuel-injected engine. The 6-speed transmission has
been designed to be very compact, enhancing the
overall narrow 3-cylinder design.
The wheelbase, seat height,
fuel tank width, rake and other dimensions are all
set to work with the qualities of the compact
3-cylinder engine to achieve a sporty, light and
neutral handling character, an upright riding
position and a narrow feeling chassis at the
excellent damping characteristics, the front
suspension is an inverted fork with 41mm inner tubes
with 5.4 inches of travel. The front suspension
features adjustment for spring preload and rebound
suspension features a linked-type Monocross shock.
The shock is positioned below the seat and features
an almost horizontal alignment. This unique
positioning contributes to mass centralization and a
slimmer body design. The rear suspension is also
adjustable for spring preload and rebound damping.
These adjustments allow for different riding
conditions and rider preferences.
Newly designed, 10-spoke
lightweight cast aluminum wheels are used, fitted
with a 120/70ZR17 front tire and 180/55ZR17 rear
tire. The tires have been designed with an
optimally-tuned internal structure that contributes
to good handling stability.
Front brakes consist of two
floating 298mm discs with 4-pot opposed piston
calipers. The newly designed calipers are radial
The aluminum, tapered-type
handlebars – a first for a Yamaha sportbike –
provide a good balance of strength and light weight.
The fuel tank, with its
deeply recessed knee grip area, contributes to a
narrow seat/tank juncture.
Newly designed, compact,
hexagonal-type rearview mirrors match the “mass
forward” design of the rest of the bike.
A newly designed
lightweight, compact, full LCD instrument panel is
adopted. The tachometer has a digital bar-type
display with gear position indicator. The electric
starter button is a new slide-type that incorporates
the engine cut-off switch is an integrated button
for a modern and high quality appearance.
The brake pedal, shift
pedal, and footrests are made of forged aluminum for
light weight and excellent appearance.
The LED taillight has
separate left and right lamps that illuminate when
the taillight is on and across the entire lens when
the brake light is on.
