Vehicle Information
Kawasaki KX125 Dirt Bike (1974-2005)
The Kawasaki KX125, produced from 1974 to 2005, is a legendary two-stroke motocross motorcycle known for its competitive performance. Throughout its extensive production run, the KX125 consistently featured a 124cc or 125cc single-cylinder, two-stroke engine. It was positioned as a high-performance machine for racing and aggressive off-road riding. Over its 31-year history, the KX125 underwent numerous significant engine and chassis revisions, rather than distinct "trims" in the automotive sense. Key evolutionary steps included the introduction of the Uni-Trak monoshock rear suspension in 1980, the first front disc brake on a Kawasaki motocross bike in 1982, and the transition to a liquid-cooled engine in 1983. Further advancements saw the addition of a rear disc brake in 1986, the KIPS power-valve system in 1988, and multiple frame redesigns, including an all-new twin-spar frame in 1990 and a perimeter frame in 1992, leading to improved handling and ergonomics. Engine improvements continued through the late 1990s and early 2000s, ensuring its competitive edge. FAQ:

Maintenance
| Component | Interval | Details |
| Transmission Oil | Every 5 to 20 hours | Interval varies by year and riding intensity (race or recreational). Two-stroke engine with separate lubrication for the gearbox. |
| Spark Plug | Regular inspection, replacement as needed | For a high-revving two-stroke engine like the KX125, replacement is more frequent than the typical 3,000 to 5,000 km for street motorcycles. |
| Air Filter | Every 2 to 15 hours | Cleaning or replacement more frequent in dusty conditions or during aggressive use. |
| Coolant | Annually or every 20 to 30 hours | Frequent level checks recommended, especially under intense riding conditions. |
