A State of Flow
Optimized intake/exhaust port shape and exhaust cam timing contribute to impressive engine performance.
With more Supercross and Motocross championships than any other manufacturer, the KX name is synonymous with winning. The KX250 motorcycle is the championship-proven machine built so you can ‘be next’. Be the next champion. Be the next hero. Be the next legend. Be the next trailblazer for an entire generation of greatness. On the KX250, your time is now.
Power to Perform
The KX™250 motorcycle is propelled by a 249cc 4-stroke engine that offers a high rev limit and ample power across the entire rev range. Low- to mid-range power and high-rpm capability give you the edge to ride ahead.
Spring into Action
The valve springs feature a high spring rate to match the high rev limit.
Serious Compression
High-performance bridged-box bottom piston contributes to strong performance at all rpm. A dry film lubricant coating on the piston skirts reduces friction at low rpm and helps with the bedding-in process.
Win From Within
A long connecting rod decreases the lateral force on the cylinder walls as the piston moves. The result is minimal mechanical loss for optimal efficiency and performance.
Designed to Win
Taking the lead on the track calls for a machine built with the tech to make it happen.
Smooth & Consistent
A coned disc-spring hydraulic clutch offers direct feel and light lever action while reducing play as the clutch heats up. Coned-disc springs make for light clutch actuation and a wide clutch engagement range. The KX™250 motorcycle features the same championship-proven hydraulic master cylinder as the KX™450 motorcycle.
Press & Go
Electric start makes for quick and easy engine starting at the push of a button.
Built for Agility
The KX™250 motorcycle features an evolution of the KX™450 motorcycle’s lightweight aluminum perimeter frame and swingarm, race-ready suspension, and powerful brakes.
Light & Nimble
The lightweight aluminum perimeter frame contributes to the KX™250’s quick handling, confidence inspiring stability, and slim ergonomics.
Soak it Up
High-performance KYB 48mm inverted coil-spring fork handles suspension duties up front. Large diameter inner tubes and large 25mm damping pistons deliver smooth action and firm damping.
Real Stopping Power
Oversized 270mm front disc contributes to strong front brake force and high level of control. The 240mm diameter rear disc offers performance for controllability and total riding confidence.
The Ergonomic Edge
An optimized riding position and unhindered rider movement help connect the rider with the performance potential of the bike.
Perfected Position
A factory-style aluminum Renthal Fatbar handlebar comes standard. With grips positioned low and close to the body, riders can shift weight forward more easily to improve front-wheel traction and increase front traction feel, to ride more confidently at the limit.
Ride with Confidence
Slim radiator shrouds are positioned close to the frame to facilitate grip for the rider’s legs.
Total Freedom
The top of the fuel tank features a design that allows a flat progression from the seat to the tank. The result is great freedom of movement when changing riding position. The seat features a slip-resistant top surface and smooth sides for an excellent balance of grip and mobility.
Find Your Fit
Class-leading ERGO-FIT adjustability allows riders to tailor the motorcycle to their body size, riding style and preference with four-way adjustable handlebar positions and two footpeg positions to choose from.
Signature Factory Styling
Sleek bodywork and factory-style graphics exude an aggressive appearance and further reflect the highly-tuned performance of the Kawasaki KX™250 motorcycle.
The Kawasaki Look
Gold finish on the oil cap and generator cover plugs tell a premium story. Black alumite rims mean business. For a distinctive Kawasaki image, the fork and rear shock adjusters feature a high-quality green alumite finish.
Break the Mold
In-mold graphics on the shrouds result in an ultra-smooth surface, greatly extending the life of the race-style graphics.
