Updated Engine

• CHAMPIONSHIP-PROVEN POWER: The 2018 KX™250F motorcycle features an updated engine that delivers increased power across the entire rev range. Get an inside look at the innovative design features.
• ENGINE: Updated cylinder head, intake cam, and revised compression ration contribute to increased power and torque across the rev range. Lightweight race-team-inspired bridged-box bottom piston to optimize combustion efficiency and plateau cylinder homing to help reduce friction.
• INTAKES: Rear fender with under seat intake channels ensure clean airflow. Revised air intake duct for increased air volume.
• FUEL INJECTION: Innovative duel-injector system with revised injector angles utilizes a downstream injector below the throttle valve and an upstream injector located near the airbox. Together, they contribute to more efficient filling of the cylinder to maximize power. The upright engine orientation with downdraft style air intake routing improves cylinder-filling efficiency, contributing to crisp throttle response and broad power delivery. Lightweight 43 mm throttle body ensures sharp, responsive power.
• EXHAUST: Revised exhaust header is designed to optimize internal engine updates.
