The Ninja 250R is a motorcycle that is made by Kawasaki. The previous generations of the motorcycle had different names based on their specific market. It was first introduced by the company in the year 1983. It was the entry level sports bike offered by the marquee and since it was first introduced it has undergone several changes. There have been 3 substantial redesigns of the bike. In certain markets the Ninja 250 is the successor of the Ninja 300.
Since the year 2008, the motorcycle has been called the Ninja 250R in every market. It is sometimes referred to by the platform designation of the bike the EX250 with a generational suffix attached to it. In the U.S. the previous models, which were the EX250 E through H were being marketed as members of the Ninja family of bikes. Outside of the United States the motorcycle was known as either the ZZR-250, the ZX-250, or as GPX-250R. One of the earlier models of the bike was the EX250-C was called the GPZ-250.
The 250R’s chassis design, ergonomics, and placement of the engine result in a motorcycle that sits in between the standard class and the sports class. The riding posture of the Ninja also sits between a standard style and a sport style.
The first generation of the Ninja was manufactured from 1983 through 1985. It was referred to as the EX250-C in production and was then sold as the GPZ-250. This version was only sold in Japan and was a belt driven version first in production in 1983. There are no commonalities between this first generation of the bike and the later generations. The 1983 version of the bike was equipped with 32 millimeter fork tubes.
From 1986 through 1987, the EX250-E was manufactured. This version was sold in Canada and the United States as the Ninja 250R in the years 1986 and 1987. Elsewhere around the world it was sold as the GPZ-250R. When it was first introduced it cost more than the Honda Rebel and many reviewers complained about the engine being slow to rev, but liked the idea of the 14000 rpm redline.
For the model year 1988, there were both changes in the engine and cosmetic changes made to the bike. The bore and the stroke of the motor were not changed and many of the major engine components were left unchanged as well, but there were minor tuning adjustments that were made. The diameters of the carburetor were reduced by 1.2 inches and the cylinder compression ratio increased to 12.4:1 from 12.0:1. There was an increase in the ignition timing and the rear sprocket. The body work was new and more fully enclosed and was complimented for being quite stylish.
There were three models encompassed by the third generation of the bike. The EX250-F was the most widespread version. It was the E model that saw a total revamp and was sold as being the F from 1988 through 2007 in the U.S. The model was received in Canada in 1988/89.
The second model of the third generation was the EX250-G and it was only sold in Japan. It offered a wider wheel base and tire and dual front brakes.
The EX250-H was sold in Canada as the Ninja 250R from 2000 through 2002 and then it was renamed ZZR-250. This version had some similar parts as the F.
In the year 2008 the EX250 received the most extensive redesign. The J is now known as the 250R around the world. There are some parts of the 3rd generation version still found on the latest model, but the appearance was redone in order to bring the bike out of the 90s and into the 2000s.
