In response to such market demand, Kawasaki started the sale of the ER-4n, a naked sport-model motorcycle that gives expression to the stylish rider with a unique design that integrates a sharp, urban sensibility with masculine strength.

With its compact and highly rigid diamond-shaped steel frame chassis, the ER-4n combines superior riding performance with easy handling.

Its lightweight and compact liquid-cooled, four-stroke, parallel twin-cylinder DOHC four-valve engine (399 cm3) delivers engine performance that is smooth and powerful at low- and mid-range speeds, while its fuel injection system and three-way catalyzer provides superior environmental performance in conformance with the 2007 Japanese national emissions regulations for motorcycles.

  • 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.
