Quick-Revving, 649cc Parallel-Twin Engine
Liquid-cooled, DOHC, 8-valve fuel-injected twin cylinder delivers smooth, responsive performance, especially in the low to medium rpm range
Excellent mid-range power, exceptional roll-on response and impressive passing performance make even commuter traffic enjoyable
Silky smooth engine vibes via a 180° crankshaft-driven balancer shaft, which in turn drives the water pump
Oil jets on the connecting rod big ends spray oil on the undersides of the pistons to aid cooling
Lightweight plug-mounted ignition coils deliver a hot spark and save space
Wide radiator offers plenty of cooling efficiency
Coolant routing travels directly to the engine cases, then on to the cylinder and head through internal passages, which keeps external plumbing to a minimum
Fine-tuned shift lever position is easy to use

Compact Engine Design
Powerful twin-cylinder engine is the most compact in its category, which helps reduce the dimension of the entire motorcycle and allows use of a slim, minimalist frame
Triangular setup of the crankshaft and transmission shafts makes the engine short front-to-back
Transmission input shaft, output shaft and change drum are contained in a “cassette”-style package that allows a compact layout and eases transmission maintenance chores
Semi-dry sump design reduces engine height
Plated, linerless aluminum cylinders with a narrow cylinder pitch keep the engine light and slim

Digital Fuel Injection
Fuel injection settings permit healthy bottom-end torque while letting the engine rev fast
Sub-throttle valve equipped 38mm Keihin throttle bodies offer optimum performance and rideability
Located behind the main throttle valves, the sub-throttles are controlled by the DFI® system ECU for a precise throttle response, similar to a constant-velocity carburetor
Auto-fast idle system simplifies starting and helps ensure the catalyzer reaches optimum temperature quickly
The lightweight fuel pump is mounted inside the fuel tank.

Vibration Control
Rubber upper-rear engine mounts decrease the vibration transferred to the rider through the seat
Handlebar is rubber-mounted to lessen vibration transmitted through the handle grips
Rider and passenger footpegs are rubber coated to further reduce vibration

Lighter Handling Trellis Frame
Frame has all the key ER-6n elements — slim, low, lightweight and compact design that is narrow at the knees and footpegs for rider comfort and control
The strong, high-tensile steel trellis frame not only looks lightweight, it is — rivaling that of aluminum frames
Balanced rigidity, achieved through extensive 3D analysis, translates directly into superb handling
The frame, rear suspension and swingarm designs flow together with an integrated line running from the steering head to the rear hub
Short front-to-back dimensions of the engine allow for a long swingarm and a short wheelbase combination that contributes to the light and nimble handling

Cleaner Emissions
Efficient fuel injection and a three-way catalyzer inside the exhaust produce very low emissions, able to pass the stringent Euro-III emission regulations
Utilizes a compact and light 300-cell catalyzer unit
Under-engine muffler placement improves mass centralization and the bike’s low center of gravity
The exhaust pipe bend and under-engine muffler arrangement contribute to the ER-6n’s attractive styling

Rigid Swingarm
Swingarm stiffness adds balance to the frame’s rigidity — due primarily to the rubber engine mounts
The D-shaped cross-section swingarm, stabilizer, chain adjuster design and elegant one-piece rider/passenger footpeg stays complement the ER-6n’s high-quality appearance

Instruments/Controls
Stacked instrument cluster has a sharp design and clean layout with an analog speedometer that uses white LED backlights for excellent visibility at night
The multi-function LCD screen has amber backlighting and its features include a fuel gauge, bar-style digital tachometer, clock, odometer and dual trip meters
Inner cover inside the front cowl provides a clean appearance in this area
Handlebar mount design and curved shapes on the brake master cylinder reservoir and clutch lever contribute further to the ER-6n’s masculine appearance

Suspension
Front and rear suspension settings match the frame and swingarm rigidity values for lighter, rider-friendly handling
Shape of the 41mm fork lower ends around the axle shaft adds to the bike’s performance and high quality image

Confidence Inspiring Ergonomics
An ideal handlebar, seat and footpeg relationship results in a comfortable and natural riding position suiting a wide range of riders
Frame narrows just aft of the fuel tank enabling a slimmer seat, making the reach to the ground even easier
The offset single-shock rear suspension layout with the battery located beside the shock instead of beneath it allows a lower seat height as well
Low seat height and slim overall design make it easy to plant both feet firmly on the ground when stopped
Aluminum passenger grips are positioned and shaped for easy grabbing by the passenger

Sharp Masculine Styling
Angular, stacked dual headlight and shroud contribute to the ER-6n’s masculine image and features two-position lights
Headlights can be adjusted behind the headlight cover
Reinforcing the ER-6n’s masculine styling, the sharp, edgy radiator shrouds feature integrated front turn signals with clear lenses and orange bulbs and forward-leaning lines
A flush-surface fuel cap and its sharp-edged motif give the tank a distinctive look
The ER-6n’s compact front-to-rear appearance is enhanced by the short front cowl, short rear cowl with its LED tail light and shrouds that start behind the front fork
Finishing out the bike’s aggressive image is a sharp tail cowl design featuring a slimmer rear mud flap and turn signals that can also function as hazard lights
A long front fender keeps the water splashing to a minimum and its two-tone design matches the ER-6n’s light, compact theme
An inner rear fender helps keep the underside of the tail cowl clean
Storage options include four tie-down hooks for baggage or a spare helmet to be secured to the seat and a storage space under the seat with room for a U-lock or similar device

Brakes
Dual 300mm front petal disc brakes with twin 27mm piston front brake calipers and a single 220mm rear petal disc deliver plenty of braking power
Housed in a curved brake master cylinder reservoir , the front brake lever utilizes an optimized ball-joint and pivot location to deliver smooth actuation of its 14mm master cylinder piston

Wheels
Attractive six-spoke supersport-style wheels augment the bike’s light look while reducing unsprung weight

Mirrors
Mirror design is a similar supersport style and offers an unparalleled rear view
