2014 Kawasaki KX250F, For almost a decade, no other bike has spent more time on AMA Supercross and Motocross podiums than the Kawasaki KX250F. It continues to lead the way, on the race track and with the enthusiast publication critics, who consider it to be one of the best 250Fs to ever put a wheel on the race track. Along with the KX250Fs race-proven performance, no other production motocross bike offers as much adjustability, fine-tuning capabilities and rider customization when it comes to motor and suspension. Right off the production line, the KX250F gives a factory advantage to the privateer racer it could be the difference between qualifying for the main and making the podium Factory-Replica 4-Stroke Engine The exhaust pipe has a short header for increased top-end performance while a resonator helps boost low-end power and reduce noise. High-performance piston, featuring the same design used on our factory racers, contributes to improved performance at all rpm. A short skirt, reinforced external ribs and the industrys only mass-production use of a bridged-box bottom, featuring fully flush internal bracing, results in a lighter, stronger piston. Semi-dry sump lubrication system for quicker engine response. The majority of oil is stored in the transmission to keep excess oil away from the crankshaft and prevent power-robbing stirring loss. With only a shallow chamber to collect oil at the bottom of the crankcase, where a scavenge pump moves it to the transmission, the crank is located as low as possible to help lower the center of gravity. Twin oil pumps ensure proper lubrication and oil scavenging for optimum performance. To eliminate external oil lines, oil passages are built into engine cases to reduce weight and improve reliability. Race-tuned 4-Valve Cylinder Head Straight-Shot intake tract for more direct air flow from the airbox to the combustion chamber. The more downdraft configuration contributes to stronger top-end performance. Intake valves have a thick head and are made of a special titanium alloy for increased strength and durability. Lightweight titanium valves (31mm intake and 25mm exhaust) reduce reciprocating weight. Valves are coated with an oxidized membrane treatment to resist wear. Special valve seat material helps prevent wear on the titanium valves. Located on the exhaust camshaft, the AutomaticCompression Release (KACR) Digital Fuel Injection System allows for easy starting. The ECU has three pre-programmed ignition maps that allows riders to change DFI settings by simply replacing a coupler located on the steering stem. Riders can choose between Standard, Hard or Soft terrain settings to suit riding conditions. 43mm throttle body provides easy starting, sharp throttle response, stable fuel delivery over jumps and whoops, and automatically compensates for changing atmospheric conditions to eliminate the need for changing jetting. No battery, fuse or relay system. Large-diameter generator provides necessary power to r
