The ER-6n gets a vestigial flyscreen around its headlight or instrument pod, but for the most part the fairing of this naked style .the clean, size-efficient engine delivers good fuel economy and also meets stringent emission regulations, thanks to its precise fuel-injection and a three-way catalyzer system. The key to the ER-6n’s slender size is its compact liquid-cooled, fuel-injected, DOHC 8-valve 649cc parallel-twin engine, which permits the use of a narrow, lightweight frame. Its fuel injection settings grant the engine plenty of bottom-end torque and smooth low-mid rpm response. Its coolant is routed to the cylinder and head through the engine cases, reducing the number of hoses and simplifying the cooling system.
The instrument cluster is uniquely stacked with a sharp design and easy layout from the analog speedometer to the multi-function LCD screen. The instrumentation features include a fuel gauge, bar-style digital tachometer, clock, odometer and dual trip meters. Besides the rubber coating on the footpegs, the passenger also benefits from the easy to reach aluminum grab rails — nothing like a relaxed passenger to allow the rider to fully enjoy the ER-6n’s friendly ergonomics and versatile cockpit.
Quite simply, this is a motorcycle that both novice and experienced riders can be at home on and equally comfortable employing its assets to the fullest, whether it be navigating urban environs or enjoying a weekend canyon run.
2010 ER-6N A BEST NAKED BIKE PERFORMANCE
2010 ER-6N FEATURES:-
• 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
• 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.
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• 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
• Mirror design is a similar supersport style and offers an unparalleled rear view
• 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
• Attractive six-spoke supersport-style wheels augment the bike’s light look while reducing unsprung weight
• Stacked instrument cluster has a sharp design and clean layout with an analog speedometer that uses white LED backlights for excellent visibility at night
