Kawasaki KX description
2006 Kawasaki KX250F, Clean and ready to ride! - Just two short years after it was introduced to American motocross racers, the championship-winning KX250F motorcycle has been revamped – even though it already has five titles under its proverbial belt. Numerous changes have been made to the potent KX250F. It produces significantly more power than the 2005 model it replaces, and like the new flagship KX450F, the KX250F sports an all-aluminum perimeter frame. The 249cc, liquid-cooled, four-stroke engine now gives the KX250F a harder-hitting powerband, especially from mid- to high-rpm, and it extends that smooth, traction-grabbing power into the over-rev range. Additional enhancements include revised intake and exhaust ports, and a revised combustion chamber for stronger low- to mid-rpm performance, while new cam profiles and a higher 13.5:1 compression ratio improve high-rpm performance. To compensate for the increased output, the piston now has a thicker crown. Other engine modifications include stiffer valve springs to help ensure reliable valve control at high rpm; a surface-hardened crankshaft for additional rigidity; more efficient oil pumps that increase oil flow by nearly 20 percent; a new stick ignition coil that reduces overall weight; and newly designed, high-capacity Denso radiators that deliver superior cooling performance due to their more tightly packed cores and new fin design. Kawasaki also revised the timing and lift of the decompression system, so starting the KX250F is even easier. The clutch and five-speed transmission have also been modified to include new friction plate material and stiffer clutch springs for improved clutch feel, and the gears have beefier dogs to match the more-powerful engine. Kawasaki engineers have also given the KX250F shift drum a new cam to improve shifting feel. The most visible change to the KX250F is the aluminum perimeter frame. As with the KX450F, Kawasaki engineers combined their experience designing steel perimeter KX frames and techniques used to construct the Ninja ZX-10R sport bike chassis to create an all-new aluminum perimeter frame. Comprised of forged, extruded and cast aluminum parts, the strong but light design gives the KX250F the best possible balance of torsional and longitudinal rigidity necessary for superior handling characteristics. The frame was designed so that the center of gravity and key chassis dimensions would work together to enhance the rear tire’s ability to drive the KX250F forward instead of squatting under acceleration. Additionally, the four-stroke engine sits in an upright position within the new frame to further aid overall traction. The slim profile of the KX250F frame, two-piece radiator shrouds that leave the upper frame spars exposed, and careful design of the remaining bodywork make the KX250F feel light

WSBK 2013: Phillip Island Race Report
Mon, 25 Feb 2013Max Biaggi who? The Roman Emperor’s retirement after winning the 2012 World Superbike Championship marked the end of an era for Aprilia, with the 2013 campaign marking the first without Biaggi since the Italian manufacturer came back to the WSBK scene with the RSV4. If Aprilia misses its two-time WSBK Champion, it sure didn’t show it with a dominating display at the 2013 season opener in Australia.
