2011 Kawasaki ER-4n | Engine
- The ER-4n has a liquid-cooled, four-stroke, parallel twin-cylinder DOHC four-valve engine (399 cm3). The distinctive parallel twin-cylinder engine delivers power characteristics that are powerful at low- and mid-range speeds and respond agilely at high speeds.
- In addition to fuel injection, the ER-4n is equipped with sub-throttle valves to optimize intake air. With excellent throttle response and smooth engine performance at normal speeds, it is both a joy to ride and easy to handle.
- With its short silencer located under the engine, the ER-4n has a distinctive design in harmony with its lower fairing. It also results in a greater concentration of mass and lower center of gravity. Equipped with a built-in three-way catalyzer, it offers superior environmental performance in conformance with the 2007 Japanese national emissions regulations for motorcycles.
- With its upright riding position, the ER-4n is both comfortable and nimble, making it both easy to handle and a joy for riders wanting complete control over their motorcycle.
- The ER-4n’s narrow parallel twin-cylinder engine and compact diamond-shaped steel frame result in a streamlined chassis, making it easy to keep both feet on the ground.
- With dual 300-mm petal disks in front and single 220-mm petal disk in back, the ER-4n has front and rear disk brakes to provide excellent braking power and heat dissipation.
- The ER-4n’s aluminum grab bars may be sharp looking but their shape and positioning also ease fatigue on long rides and make riding with a passenger more convenient.
- The ER-4n’s unique front face with twin vertical headlights, its forceful radiator shroud with built-in turn signals, and its sharp-cut tail cowl give the chassis design an integrated look that is at once stylish and aggressive.
- The ER-4n’s style is matched by the leading-edge design of its instrument panel, equipped with both an analog speedometer and a multi-function LCD display. The LCD display includes a digital bar-style tachometer, fuel gauge, clock, and odometer/trip-meter.
- The ER-4n’s LED taillights are compact and provide excellent visibility. The rear view is sharp and stylish.
