2009 Kawasaki ER-6f
Sportier Performance. New Ninja Looks.
Building on the key concepts of its highly acclaimed
predecessor, the new ER-6f continues to offer a package
that is both fun and easy to ride, and matches its
sporty street performance with aggressive new Ninja
supersport styling.
When the original ER-6f (Ninja 650R in North America)
made its debut three years ago, it offered the market
a unique combination of performance, accessibility
and sophisticated good looks. More mature, the new
ER-6f improves on this combination while maintaining
the key character of its predecessor.
The most apparent change is the ER-6f's decidedly
sportier appearance. Sharper, more aggressive new
styling gives the bike the look of a modern supersport
machine - any similarities to our Ninja supersport
models are purely intentional.
The characteristic trellis frame and offset laydown
rear shock remain, but the frame has been completely
redesigned with even greater attention to detail giving
the new bike an even higher quality finish.
Changes to the slim, compact chassis were not only
cosmetic. Revisions to rigidity balance and suspension
settings, and the addition of rubber mounts result
in reduced vibration and lighter handling, enabling
the ER-6f to improve on the comfort and rider-friendly
handling qualities of its predecessor. Both are excellent
traits, whether negotiating city traffic, carving
corners in the hills or cruising down the highway.
Further, the natural riding position and ergonomics
benefit from a revised seat that makes the reach to
the ground even easier.
The 649cc, liquid-cooled Parallel Twin also receives
some tweaks. The torquey engine revs more quickly,
adding to riding excitement, and response is smoother,
especially at low-mid rpm. The linear quality is non-intimidating
and offers a level of control that can easily be exploited
for sporty riding.
Sportier, even easier to handle and wrapped in seductive
Ninja supersport styling, the new ER-6f enables riders
to experience the fundamental joy of motorcycling.
Engine
Compact, Quick-Revving Engine
The balance of compact size and good power offered
by the ER-6f's predecessor was the key to its success.
To fit into its trim package, an In-line Four would
have been too wide and a V-Twin too long. The only
engine design that offered both good power characteristics
and the requisite compactness was a Parallel Twin.
While maintaining this balance, the new engine gets
a number of tweaks that offer smoother low-mid response
and a quicker-revving character.
Engine Performance
Liquid-cooled, DOHC, 8-valve 649 cm3 Parallel Twin
with fuel injection delivers smooth, responsive performance,
especially in the low and medium rpm ranges. The engine
was tuned for rider-friendly power characteristics
that will inspire confidence in new riders.
Revised fuel injection settings result in smoother
response (especially below 4,000 rpm) and contribute
to the new ER-6n's quicker-revving character.
The engine's excellent mid-range power characteristics
make the bike especially fun to ride at medium speeds
on city streets. Roll-on response is exceptional,
offering impressive passing performance.
Large-bore 38 mm throttle bodies feature sub-throttles
for high power output with smooth, sensitive throttle
response.
Wider radiator (by 40 mm) offers increased cooling
efficiency (17.4 kW >> 19.4 kW).
Compact Engine Design
The ER-6f's 649 cm3 liquid-cooled power unit is
the most compact engine in its category. Don't let
the words "Parallel Twin" fool you. This
engine is loaded with innovative technology that enabled
the realisation of its compact design and surprising
performance. Its abundance of Ninja technology and
know-how explains why this compact and lightweight
machine can outperform so many of its middleweight
competitors (many of which have larger displacement).
Triangular layout of the crankshaft and transmission
shafts makes the engine very short front-to-back.
Transmission input shaft, output shaft and change
drum are contained in a "cassette"-style
package that both allows a compact layout and facilitates
transmission maintenance chores.
Semi-dry sump design reduces engine height.
Plated, linerless aluminium cylinder is lightweight,
and the narrow cylinder pitch reduces engine width.
Under-engine muffler improves mass centralisation
and lowers the bike's centre of gravity.
Euro-III Compliant
The combination of efficient fuel injection and
a 3-way catalyser inside the muffler make for very
low emissions which pass the stringent Euro-III regulations.
300-cell catalyser offers more compact size and lighter
weight compared to previous 200-cell unit. Muffler
internals were revised to suit the new catalyser.
Chassis
Light-Handling Chassis
The key to the ER-6f's compact size is its amazingly
compact Parallel Twin engine, which permits the use
of a narrow, lightweight frame. The result is a bike
with the dimensions of a 400 and the power of a 650
that welcomes beginners with a "Come on, let's
go for a ride!" attitude, while also offering
plenty of performance for more experienced riders.
Changes to the frame, swingarm and suspension result
in reduced vibration and lighter handling, making
the new ER-6f more accessible than ever.
Compact Package
All-new frame maintains the key design elements
of its predecessor. Together with the compact engine,
the new frame's elegant design realises a package
that is slim, low, lightweight and compact.
The compact engine allows use of a slim, minimalist
frame, resulting in a design that is narrow at the
knees and feet.
The compact engine also allows an extremely short
wheelbase, giving light and nimble handling.
Because a long swingarm can be used, rear suspension
action and handling are both improved.
3D analysis was used to achieve the ideal stiffness
balance for the frame, contributing to the superb
handling characteristics.
The frame is constructed of high-tensile steel,
giving it a lightness rivalling that of aluminium
frames.
The layout of the offset single-shock rear suspension
allows the battery to be located beside the shock
instead of beneath it. This elegant arrangement allows
a lower seat height as well as a slim design.
The same characteristics that make it fun to ride
(responsive handling and rider-friendly ergonomics),
also make the ER-6f ideal for new riders.
A short wheelbase and tight turning radius contribute
to the ER-6f's high manoeuvrability.
Reduced Vibtration
Rubber mounts instead of rigid mounts used for the
upper-rear engine mounts reduce vibration transmitted
to the rider through the seat.
Handlebar is rubber-mounted to reduce vibration
transmitted through the handle grips.
Rider and pillion footpegs are rubber coated to further
reduce vibration.
Light Handling
Changes to the frame to reduce rigidity and improve
appearance also contribute to the ER-6f's lighter
handling.
New swingarm has higher rigidity to balance the
reduced rigidity of the frame (due primarily to the
rubber engine mounts). Overall, chassis rigidity is
the same as that of the previous models.
Front and rear suspension settings were revised to
match the changes to the frame and swingarm. Together
with the new frame they offer lighter, rider-friendly
handling.
On ABS models, the front fork's spring rates are
slightly stiffer in order to optimise braking performance.
Rider-Friendly Ergaonomics
The riding position was specially designed to inspire
rider confidence. An ideal relationship between the
handlebars, seat and footpegs results in a comfortable
and natural position suitable for a wide range of
riders.
The narrow frame and engine make for an overall narrow
package, allowing the rider to keep his or her knees
and feet close together.
Thanks to the low seat height and slim overall design,
it's easy to keep both feet firmly on the ground when
stopped, an important consideration for many riders.
Narrowing of the frame just aft of the fuel tank
enabled the seat construction to be revised, making
the reach to the ground even easier.
Aluminium (previously plastic) passenger grips are
positioned lower and have a revised shape, making
them easier for tandem riders to grab. Increased passenger
confidence thanks to the improved grip also makes
it easier for riders when carrying a pillion. (Non-North
American models only.)
Styling
Sleek, Supersport Styling
Styling inspired by our Ninja supersport models
gives the full-fairing ER-6f the look a modern supersport.
Sharper, edged lines move forward, giving the bike
a more aggressive, crouching appearance. Simple in
design, the ER-6f avoids all superfluous design flourishes;
lines were made to flow as long as possible. The new,
taller fuel tank, minimalist-design fairings and sharp
tail cowl give the bike a compact appearance. Attention
to the smallest details contributes to the new bike's
high-quality finish.
Bodywork
New dual headlamp design features twin position
lamps - just like on our Ninja supersport models.
The designed shape of the multi-reflector headlamp's
bulb hoods is an example of to the attention given
to detail on this model.
Windscreen set at a sharp angle contributes to the
supersport image. A lip at the top of the screen helps
to deflect air away from the rider. A duct in the
centre of the cowling creates an "air curtain"
which reduces wind buffeting at higher speeds and
improves rider comfort.
Fuel tank is taller - especially noticeable when
viewed from the side - which adds to the bike's crouching
appearance. Sharp-edged line motif gives it a look
very distinct from that of its predecessor. Flush-surface
fuel cap contributes to the sleek lines.
Side view of the front cowling and the fairings
(especially the top corners at the front) have distinctive
Ninja design elements.
Fairing design judiciously combines coloured and
black panels to create a compact appearance - an approach
similar to that used on the Ninja ZX-10R.
Revised front turn signals are integral with the
fairings, contributing the bike's supersport styling.
Clear turn signal lenses with orange bulbs further
enhance the machine's high-quality appearance.
Viewed from the rear or from the side, the tail cowl
and seat's sharper design is evident. Thin new LED
tail lamp and rear turn signals reinforce this image.
Longer front fender reduces mud splash. Two-tone
design contributes to the light, compact appearance.
The addition of an inner fender helps keep the underside
of the tail cowl clean and contributes to the ER-6f's
sporty look.
New license plate bulb housing and slimmer rear
mud flap add to the sharp image of the tail.
Frame/Rear Suspension
While the frame is completely new, its design continues
to be a key component of the ER-6n's identity. Like
on its predecessor, the new ER-6f's bodywork accentuates
the frame, rather than hiding it.
The design of the frame, rear suspension and swingarm
create an integrated line running from the steering
head to the rear hub.
A trellis frame of high-tensile steel gives the
bike a lightweight appearance. 3D analysis was used
to achieve the target rigidity and stress values.
Offset laydown rear single-shock suspension flows
smoothly from the frame to the swingarm.
The braced steel swingarm follows the lines of the
frame and rear shock, its triangulated design contributing
to the machine's innovative styling.
Swingarm now has a D-shaped cross-section (instead
of a square tube). The pipe-like design of the new
swingarm and revised stabiliser further contribute
to the ER-6f's higher-quality appearance.
Elegant design of the one-piece rider/passenger footpeg
stays complements the new swingarm and stabiliser.
Finish at frame joints is much cleaner, improving
overall quality of the bike.
Instruments
Flowing lines are also evident in the design of
the new MotoGP-inspired multi-function instrumentation.
Features include a new fuel gauge, digital speedometer,
clock, odometer, dual trip meters and a bar-style
digital tachometer like our MotoGP racer. The new
layout allows the clock and trip meter to be viewed
simultaneously. Red backlighting for the LCD screen
adds to the sporty image.
Panelling around the instrument panel gives the
inside of the front cowl a clean, finished appearance.
Mirrors
New supersport-style mirror design is similar to
that on the new Ninja ZX-6R. Positioned 14 mm further
out from the centreline, they also offer an improved
rear view.
Engine
The attractively bent exhaust pipes and under-engine
muffler arrangement contribute to the ER-6f's attractive
styling.
Brakes/Wheels/Tyres
Triple petal disc brakes contribute to the bike's
sporty image.
Attractive 6-spoke supersport-style wheels give
the bike a light look while reducing unsprung weight.
Little Details
Redesigned handlebar holder contributes to improved
appearance.
Redesigned brake master cylinder reservoir has a new
curved shape.
New clutch lever has a rounded shape, contributing
to improved appearance in the handle area.
Lower ends of the fork have new shape (around the
axle shaft) that also contributes to the bike's high
quality look.
Revised chain adjuster design contributes to improved
appearance in this area.
Suspension / Brakes
Brakes
Dual 300 mm front petal disc brakes and 220 mm rear
petal disc look great and deliver plenty of braking
power.
In addition to the very effective petal disc brakes,
customers looking for an added degree of reassuring
braking performance can also choose models with front
and rear ABS (available in certain markets).
Front brake lever uses a new ball-joint (instead of
a unitised piece) and revised pivot location to deliver
smoother actuation of the master cylinder piston.
Now common, standard and ABS models both use a front
brake master cylinder with 14 mm piston, and twin-piston
front brake calipers with 27 mm pistons.
While performance and touch of standard models is
maintained, with the new master cylinder pistons and
larger caliper pistons, braking performance and lever
touch on ABS models is noticeably improved. As the
lever is actuated, grip is immediate (minimal lever
play) and firm, and a new ABS programme with a wider
range of conditions ensures very consistent braking
performance. The new settings contribute to excellent
road-holding performance, especially on roads that
are less than circuit-smooth.
Additional Features
Engine
Fine-tuned shift lever position is easier to actuate.
Auto-fast idle system simplifies starting and ensures
the catalyser reaches optimum temperature quickly.
Simplified cooling system routes coolant through the
engine cases to the cylinder and head to reduce external
plumbing.
180 ° crankshaft drives a balancer shaft for silky
smooth engine operation. The water pump is driven
off the right end of the balancer shaft.
Oil jets located in the rod big-ends direct oil to
the undersides of the pistons for added cooling.
Lightweight plug-mounted ignition coils deliver a
hot spark while saving space.
Newly designed lightweight fuel pump mounted inside
the fuel tank.
Chassis
Despite the addition of a fuel level sensor (to
enable the fuel gauge function), fuel capacity remains
the same.
Four tie-down hooks allow baggage or a spare helmet
to be secured to the seat.
Under-seat storage space has room for a U-lock or
similar device.
The turn signals also function as hazard lights.
