2011 Kawasaki KX 250F | Motocross

It’s an old refrain: The factory guys get all the good stuff. Their bikes are faster, lighter and just plain tricker than the motocrossers you can buy off the showroom floor. There’s some truth there. But that’s changing. The gap between production and factory-prepped motocrossers has never been narrower. And with the introduction of Kawasaki’s massively reworked 2011 KX™250F, that gap just shrank a little more.
Features
- New Digital Fuel Injection (DFI) system
- New Showa Separate Function Fork (SFF) divides spring and damping functions; springing in the right leg and damping in left provide less friction, better performance and easier adjustability
- Increased engine performance via higher compression and exhaust/intake changes
- High-performance piston featuring Bridged Box-bottom design
- Stainless steel exhaust features longer header section and larger-volume muffler
- Revised suspension settings front and rear aimed at race-experienced riders
Engine Features
- 249cc, liquid-cooled, four-stroke, four-valve, single-cylinder DOHC engine delivers hard-hitting power across the rpm range
- Modified intake valve timing and cam profile for increased valve lift improves high-rpm power production
- Intake valve spring tension increased to control more radical cam timing
- Digital Fuel Injection (DFI) system allows consistent fuel delivery, quick starts and easy adjustability
- Engine tuned to achieve the widest possible torque band to maximize traction through a greater percentage of the rev range
- Race-experienced riders able to harness high-rpm performance that extends way into the over-rev
- Sprocket-style chain drive roller helps reduce the effect of driveline lash and engine braking for smoother and faster corner entries
- Crank web design features a balance factor on par with the factory racers for reduced engine vibration, smoother power delivery and increased performance in the mid-high rpm range
