The Kawasaki KS125 was a 125cc, 2-stroke, dual-purpose motorcycle manufactured by Kawasaki from 1974 through 1975. The KS125 was the successor to the Kawasaki F6 and though it had the same rotary disc valve engine, it had 13 horsepower as opposed to the 14.5 the F6 produced.

Europe calls

Kawasaki had concentrated on the U.S. market for years leaving the 125cc trail bike or enduro market in Europe (especially France) to Yamaha and Suzuki. In 1974, Kawasaki introduced the KS125 thus ending the Yamaha DT125 reign.

Excellent Beginner's Machine

The F6 derived KS125 was the perfect answer, for it combined a fiery temperament with first-class cycle components, Its new engine incorporated the classic induction system by rotary-valve, long typical of lightweight Kawasakis, and thus developed 13 hp at 6500 rpm, More highly-tuned than its rival, the KS was unhappy during low-speed maneuvers, off-road or in town, and was less of an all purpose machine, On the other hand, it was an excellent beginner's machine for enduro and was class-leader when it came to covering rutted stages rapidly,

More Comfortable and Refined

Redesignated the "KE125A" for 1976, the 125 Kawasaki trail bike became more comfortable and refined. A stylistic freshening kept it going into 1979, but it gave way in 1980 to the new KE125-A7, which was more powerful (13.5hp) and more sporty and took its layout from the marque's motocross machines -it had greater suspension travel.
