2015 Husqvarna FC 450, 2015 Husqvarna® SHOCK WAVE OF POWER Strong, yet usable engine performance catapults the FC 450 into contention at the top of the 450 class. The FC 450 has astonishing force from the SOHC engine, incredible handling from the lightweight, cutting-edge chassis, and embodies the core values of Husqvarna. The standard electric start and handlebar-mounted map switch make the FC 450 one of the most advanced Motocross bikes on the market. Features May Include: ENGINE The compact SOHC design delivers exceptional power and torque over an extremely wide rev range. The accessible, class-leading performance of the FC 450 engine allows riders to confidently rocket of the corners, power down the straights and clear any jump. The single overhead cam in the cylinder head actuates four lightweight titanium valves, only 32 grams each, via lightweight and rigid rocker arms (DLC coated on the intake). The diameter of the intake valves is 38mm, while on the exhaust side it is 33mm. The broad power band of the FC 450 stretches to 11,500 rpm, peaking at 60 hp while maintaining exceptional torque low in the rev range. ENGINE MANAGEMENT SYSTEM The electronic fuel injection and 44mm throttle body of the Keihin Engine Management System on the 4-stroke models, combine to offer amazing power delivery and efficiency at all engine speeds. The injector was positioned on the bottom of the inlet tract for optimal air-fuel mixture, resulting in crisp throttle response and class-leading power. CRANKSHAFT, CONROD AND PISTON The FC 450 features an industry-leading Pankl produced crankshaft and conrod in order to ensure that the high power output and torque of the 450cc engine are combined with durability and long service intervals (100 hours before changing con rod, con rod bearing and crank pin). To achieve this goal, the lightweight crankshaft has a pressure lubricated plain big end bearing, and two force-fitted shells that run directly on the crank pin. The König bridge-box-type piston weighs 330g and has a bore of 95mm, it was developed to reduce engine vibration and optimise strength. The compression ratio is 12.6:1 for an amazing peak output of 60 hp. SWINGARM The single component construction of the aluminium swingarm eliminates welding, providing more reliability, stability and safety, as well as superior quality and consistent behaviour over time compared to other construction processes. The specific flex engineered into the swingarm makes the most of the Husqvarna engine characteristics in terms of traction and power. FRAME The engineers in Research and Development had clear objectives in terms of torsional rigidity, longitudinal stiffness and weight. The goal was to give the rider optimal feedback and complete confidence in every situation. This was achieved by designing the li
