Kawasaki Ninja 250R

The Kawasaki Ninja 250R is a sport motorcycle originally introduced by Kawasaki Motors in 1983. As the marque's entry-level sport bike,it has proven to be a top seller, continuously experiencing double-digit sales growth.It is a popular machine with novices and experienced riders alike, renowned for its light handling, good fuel economy, and comfortable riding posture. The motorcycle has undergone few changes throughout its quarter-century lifetime, having received only two substantial redesigns.
The fourth-generation model is marketed as the Ninja 250R in all markets. The motorcycle is also referred to by its platform designation, EX250, to which a generational suffix is attached. In the United States, previous generations of the bike (EX250-E/F/G/H) were already being marketed as members of the "Ninja" family of sportbikes, while outside of the U.S. the bike was known variously as the ZZR-250, ZX-250, or as the GPX-250R. One of the earliest generations, the EX250-C, was given the name GPZ-250.
In 2008, Kawasaki gave the EX250 its most thorough modernization in many years. The EX250-J model is known as the Ninja 250R worldwide, regardless of market.Parts from the third generation are still found on the -J, but its redesigned exterior panels bring the smallest Ninja's appearance out of the '90s and into line with late-2000s sportbikes. The engine and drivetrain retain 30% of the -F model's parts, according to Kawasaki literature. The engine's compression and maximum torque have been lowered to provide better midrange performance, where the motorcycle spends most of its time. The redesign of the engine was a response to frustration felt by new riders, according to Kawasaki, resulting in improvements in engine response at low RPM, and making the bike smoother and "much easier to ride."Though the previous generation Ninja 250 had one more peak horsepower, or five more peak engine horsepower according to official Kawasaki specifications,according to testing by Motorcycle Consumer News,the new version's 20 or 30 percent increase in mid-range power allows the bike to pull from 3,000 rpm where previously it had to be revved to 4,000.The U.S.-spec -J model uses dual carburetors like the -F model, but the European-spec, Brazilian-spec and Thailand-spec model have a fuel-injection system. The wheels were increased in size to 17 inches, the front suspension was beefed up, and the brake rotors were replaced with a larger "petal" design. A fuel gauge was put in place of the previous model's temperature gauge, except on the Brazilian model. With the additional and redesigned equipment, the EX250-J suffered a ten kilo increase in wet weight over its predecessors.
