This is the latest evolution of the
model that introduced the “Fun. Style. Easy.”
concept to the world. Increased engine performance
makes the new ER-6n even more fun. Aggressive street-fighter
looks make it even more stylish. And a slimmer new
chassis and comfortable new seat make it even easier
to ride than before. Whether a new rider getting acquainted
with the joy of motorcycling for the first time, or
an experienced rider looking for a fun, stress-free
way to get around, the package offered by the ER-6n
has never been more tempting.
AGGRESSIVE STREET-FIGHTER LOOKS
The latest evolution of the ER-6n design
is the result of the pursuit of the beauty inherent
in a naked motorcycle. Sharp new bodywork is complemented
by a new double-pipe perimeter-style frame and
characteristic offset laydown rear suspension to create
a package with aggressive street-fighter looks. Like
on its predecessor, all lines move forward and downward,
suggesting a crouching countenance, however sharp
new bodywork gives the new machine a much more condensed,
mass-forward appearance. The ER-6n’s simple
design avoids all superfluous design flourishes, highlighting
the functionality of each of its
components. Attention to the smallest details contributes
to the new bike’s high-quality finish.
Like on its predecessor, the all-new
double-pipe perimeter-style frame is a key component
of the ER-6n’s identity. As before, the new
bodywork accentuates the frame, rather than hiding
Double-pipe design of the new frame, made from high-tensile
steel, contributes to the bike’s lightweight
The design of the frame, rear suspension and swingarm
create an integrated line running from the steering
head to the rear hub.
Offset laydown rear single-shock suspension flows
smoothly from theframe to the swingarm.
Following the lines of the frame and rear shock, the
swingarm also features the new double-pipe design,
complementing the design of the frame and contributing
to the ER-6n’s high-quality appearance. The
swingarm’s gull-arm style design on the right
side enables the more aggressive angle of the muffler.
Elegant design of the one-piece rider/passenger footpeg
stays complements the new swingarm.
Finish at frame joints is very clean, adding to the
overall quality of the bike.

Fork guards mounted under the headlamp shroud contribute
to the condensed, mass-forward image. They also offer
protection against dirt and debris for the fork inner
Similar to the design of the Z1000, the key cylinder
moves rearward to create the space needed to enable
the more compact front area. The key cylinder is now
located at the front of the fuel tank.
Fuel tank is 20 mm taller, helping to visually concentrate
the ER-6n’s mass at the front of the bike. The
of the tank slopes back in a straight line to the
Revised shrouds are narrower when viewed from the
front. Front turn signals, previously built-in to
shrouds, are mounted on the headlamp shroud.
Clear turn signal lenses with orange bulbs further
enhance the machine’s high-quality appearance.
Blacked-out side covers help make the rear of the
bike look lighter.
Sharper tail cowl is 10 mm shorter,
helping to move volume away from the rear of the bike.

to the quality finish in this area.
Triple petal disc brakes contribute
to the bike’s sporty image. Attractive 6-spoke
wheels give the bike a light look while reducing unsprung
COMPACT, QUICK-REVVING ENGINE WITH STRONGER
The ER-6n’s Parallel Twin engine
configuration was chosen as the best balance of good
power characteristics and compact size. Engine tuning
delivered both a rider-friendly character ideal for
new riders and performance to put a smile on the faces
of more experienced riders. The engine’s compact
size was one of the keys to realising the ER-6n’s
slim package. The 2012 engine offers more low-mid
range torque for more fun and greater usability in
everyday riding situations, while maintaining the
smooth, high-revving character of its predecessor.
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.
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.
Intake ducts extend through the frame tubes to ensure
a source of cool fresh air for the engine. This also
contributes to the induction note, adding to rider
Air cleaner uses a paper filter element (previously
oil-wetted foam) for improved air flow and dirt filtration
Large-bore 38 mm throttle bodies feature sub-throttles
for high power output with smooth, sensitive throttle
Connector tube joining the header pipes helps eliminate
peaks and valleys in the torque curve, resulting
in smoother power delivery.
Under-engine muffler with larger volume and revised
internal construction delivers increased torque in
the everyday range below 7,000 rpm. The increased
performance facilitates control at lower rpm and contributes
to the enhanced enjoyment of the new ER-6n.
Compact Engine Design
The ER-6n’s 649 cm3 liquid-cooled
power unit is loaded with innovative technology that
enabled its compact design to be realised:
Triangular layout of the crankshaft
and transmission shafts makes the engine very short
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
Plated, linerless cylinder is lightweight,
and the narrow cylinder pitch reduces engine width.
Under-engine muffler improves mass
centralisation and lowers the bike’s centre
The combination of efficient fuel injection
and a 3-way catalyser inside the muffler result in
Revised muffler internal construction and catalyser
layout ensure clean emissions that will pass stringent
SLIMMER LIGHTER-HANDLING CHASSIS
The ER-6n’s compact size is due
largely to its compact Parallel Twin engine, which
enabled the use of a narrow, lightweight frame. While
the new double-pipe perimeter-style frame, clearly
visible, maintains the key design elements of its
predecessor, a new backbone-style rear frame design
enables an even slimmer package. Rigidity balance
of the new frame and swingarm, and new suspension
settings deliver lighter, easier
handling, while maintaining the sporty nature of the
previous model. And with a new seat contributing to
both comfort and peace of mind, care of an easier
reach to the ground, the new ER-6n is more accessible
More Compact Package
Together with the compact engine and
new rear frame, the frame’s 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
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.
Slim backbone-style rear frame design allows all components
to be positioned closer to the bike
Up top, the tubular seat rails are replaced by a single
beam (formed from interlocked C-section pieces).
The slim design enables the more comfortable seat

of rear frame is supported by two sleeves through
which the swingarm
bolt passes. This enables a narrower design between
the rider’s feet, facilitating the reach to
The new rear frame also enables an increased payload
(180 kg - 200 kg).
The same characteristics that make
it fun to ride (responsive handling and rider-friendly
ergonomics), also make the ER-6n ideal for new riders.
A short wheelbase and tight turning radius contribute
to the ER-6n’s high manoeuvrability.
The rigidity balance of the double-pipe
frame and swingarm contributes to a lighter, easier
Rigid-mount engine is a stressed member, contributing
to the frame’s idealised rigidity balance.
The swingarm’s new double-pipe design makes
use of a D-section tube (upper right tube) for optimal
Revised suspension has longer stroke front and rear,
offering both sporty handling and enhanced comfort.
Rear shock length and stroke are 2 mm longer; front
fork is 15 mm longer with 5 mm longer stroke to match
the rear. The longer strokes enable lower spring rates.
Damping was revised accordingly.
Two-piece seat features thicker cushioning
for increased comfort.
The front seat is not only thicker
at the top edge, but thanks to the new rear frame
design the plastic seat
base construction was completely revised, enabling
much thicker cushioning throughout.
Sporty looking tandem seat with thick cushioning ensures
good passenger comfort.
Ergonomic passenger grips are positioned to make them
easy for tandem riders to grab. Good
passenger confidence makes it easier for riders when
carrying a pillion.
Revised suspension settings also contribute to an
overall increase in ride comfort. Handlebar is rubber-mounted
to reduce vibration transmitted through the handle
grips and to the mirrors.
Seat bracket is rubber-mounted at the front to reduced
vibration transferred through the seat.
Footpeg stays are rubber-mounted and both rider and
pillion footpegs are rubber-coated to further reduce
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.
Slightly wider handlebar (10 mm each side) offers
larger riders a little more room.
The narrow frame and engine create a narrow overall
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
While the new seat does not lower the seat height,
its construction and the narrower distance between
the pivot covers (both possible thanks to the slim
new rear frame design) result in a slimmer package
between the rider’s feet. Riders are now able
to put their feet on the ground approximately 50 mm
(each side), which makes the reach to the ground feel
Dual 300 mm front petal disc brakes
and 220 mm rear petal disc look great and deliver
plenty of braking power.
Front brake master cylinder uses a 14 mm piston; 27
mm pistons are used for the twin-piston front brake
Revised front brake pads for non-ABS models offer
increased stopping 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).
