• As power is relative to weight, KTM engineers have worked tirelessly to produce an engine with class-leading power and the lowest weight in the MX2 category. The end result is a motorcycle that sets the class benchmark for power-to-weight ratio and is the strongest in MX2 competition. With many updates, including valve timing, exhaust, airbox and EMS (engine management system), the power unit produces more torque and power across the entire rev range than ever before. Its compact architecture contributes to excellent mass centralization, which supports the easy rideability of the bike. In short, the combination of a compact engine layout and unrivalled power makes the new KTM 250 SX-F an undisputed winner once again.
• Engine: The engine of the KTM 350 SX-F features a compact and very light (60lbs) construction. Its DOHC (double overheard camshaft) design with lightweight titanium valves and DLC coated cam followers allows for lively but strong engine characteristics. Fitted with the latest electronic fuel injection system and an E-starter, it has an extremely wide usable speed range, high performance and incredibly efficient rideability. The KTM 350 SX-F engine shares the same layout as the 250 SX-F, resulting in its playful handling similar to a 250 machine by from reducing the moving masses to a minimum.
• Cylinder head: The centerpiece of the compact DOHC engine is the cutting-edge cylinder head. It features two overhead camshafts, which activate the titanium valves via super-light finger followers with a hard DLC coating. New lateral brackets (now made of aluminum instead of steel) allow an efficient fixation of the engine to the frame and shave off even more weight.
• Crankshaft: The 250 SX-F has an extremely rigid crankshaft, which features a connecting rod with a plain big end bearing with two force-fitted bearing shells running directly on the crank pin. This design
