2021 KTM Dual Sport Motorcycle 350 EXC-F

Engine & Exhaust

• Engine: Compact dimensions with an unbelievable power output, the KTM 350 EXC-F’s fuel-injected DOHC engine offers the best power-to-weight ratio on the market, thanks to newly developed camshafts, exhaust system and updated electronic fuel injection. Its class-leading power delivery is available throughout the entire rev range. The weight is reduced to 61.7 lbs (28 kg), making it almost as light as a 250, while offering power and torque closer to a 450 cc.
• Cylinder Head: The KTM 350 EXC-F has a reworked cylinder head design with a similar architecture to the previous model, but is 200 gr lighter. The 2 new overhead camshafts and flow optimized ports guarantee outstanding engine characteristics. The DLC coated finger followers, as well as the lightweight valves they actuate (intake 36.3 mm, exhaust 29.1 mm), allow for higher engine speeds, a crucial factor in the 350’s dynamic performance. The new head also features a new cylinder head cover and gasket, as well as a new spark plug and spark plug connector.
• Crankshaft: The KTM 350 EXC-F’s crankshaft is located in an ideal position close to the center of gravity, contributing to easier handling. It utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The engine’s pressurized lubrication system provides the necessary oil feed for this bearing. This design has a direct benefit for the crankshaft with extended service intervals, which are lengthened due to the plain bearing. So just pin it, all day long.
