A Legendary Comeback
Kawasaki has ignited the motocross world with the announcement of the 2025 KX 500, marking the triumphant return of the iconic two-stroke dirt bike. Revealed on January 25, 2025, during the AMA Supercross in Anaheim, the KX 500 revives a legend that dominated from 1983 to 2004. Priced around $9,999 (estimated), this modernized beast blends raw power with cutting-edge technology, aiming to reclaim its throne as the ultimate dirt bike for pros and enthusiasts. Posts on X are buzzing, with fans calling it a “game-changer” for two-stroke lovers.
Powerhouse Engine
The 2025 KX 500 is powered by a 499cc liquid-cooled, two-stroke single-cylinder engine, engineered for explosive performance. While exact horsepower figures remain undisclosed, the bike draws inspiration from its predecessor’s fearsome 60+ hp output, now enhanced with electronic fuel injection for smoother delivery and improved low-end torque. A five-speed transmission and a lightweight crankshaft ensure precise power transfer, making it ideal for motocross tracks and desert racing. The KX 500’s signature “on-the-pipe” ferocity is refined for modern riders, offering both thrill and control.
Advanced Chassis and Suspension
Built on a new lightweight aluminum perimeter frame, inspired by the KX 450, the KX 500 sheds weight while boosting agility. It features Showa 49mm coil-spring forks and a Showa rear shock, both fully adjustable, delivering 12 inches of travel for superior handling on rough terrain. The bike’s slim ergonomics, with updated bodywork and a domed air filter, enhance rider mobility. Dunlop AT81 tires, a 270mm front disc brake, and a low center of gravity ensure precise cornering and stopping power, setting it apart on the track.

Modern Tech Integration
The KX 500 embraces 2025 tech with Kawasaki’s RIDEOLOGY THE APP, allowing riders to fine-tune engine mapping via Bluetooth for Normal or Aggressive modes. Kawasaki Traction Control (KTRC) offers Weak and Strong settings to optimize grip, while a launch control system aids holeshots by reducing wheel spin. ODI Lock-On grips and ERGO-FIT adjustability enhance comfort, drawing from the Monster Energy/Pro Circuit team’s expertise. These features make the KX 500 versatile for motocross, supercross, and off-road racing.
Competing in a New Era
The KX 500 faces rivals like the Yamaha YZ250 and KTM 300 SX, but its 500cc displacement and racing pedigree give it an edge for power-hungry riders. While some X users speculate about its practicality compared to four-strokes, its lightweight design and advanced electronics counterbalance its raw intensity. Compared to the 2025 KX 250, which adopted Showa suspension and a new frame, the KX 500’s two-stroke revival taps into nostalgia while pushing innovation, as noted by Dirt Rider and Motocross Action Magazine.
