The pinnacle of Husqvarna motocross, the FC 450 uses advanced engineering techniques to not only draw 63 hp from the 450cc motor, but also position the engine shaft arrangements at the ideal centre of gravity to vastly benefit handling and manoeuvrability. The addition of launch control means perfect acceleration off the line, while class-leading ergonomics and traction control keep the rider in full control.
The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the centre of gravity as possible, significantly improving handling and agility. The lightweight valves are actuated via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response.
=>Mass centralisation → advanced handling and reliability
=>Performance → 63 hp at only 27.3 kg
The MY20 FC 450 features a compact and lightweight SOHC cylinder head. As a result of the compact design the camshaft is closer to the centre of gravity, significantly improving handling. Additionally, short valve timing offers progressive bottom-end performance and responsiveness. The camshaft features an optimal cam surface and actuates four lightweight titanium valves. The diameter of the intake valves is 40 mm, with the exhaust valves being 33 mm in diameter. Low-friction DLC coating on the rocker arm and low-friction chain guides offer optimum efficiency and reliability.
=>Cylinder head → compact design
=>Camshaft → Optimal cam surface
=>DLC coating & optimised chain guides → reduced friction
The lightweight aluminium cylinder is an engineering masterpiece. It features a 95 mm bore and a CP bridge-box-type piston that weighs only 320 g. The compression ratio is 12.6:1 for an impressive peak output of 63 hp.
=>Lightweight aluminium cylinder → 95 mm bore
=>CP forged bridged-box-type piston → high performance, reduced oscillating masses
The inertia produced by the crankshaft has been carefully calculated to deliver optimal traction and rideability from the powerful 450cc plant. The crankshaft is specifically positioned to harness the rotating mass in the ideal centre of gravity, with the end result being a lightweight and agile handling feel. A plain big end bearing comprising of two force-fitted bearing shells that ensure maximum reliability and durability, while also guaranteeing long service intervals of 100 hours.
=>Crankshaft position → ideal centre of gravity, advanced handling
=>Plain big end bearing and force-fitted bearing shells → increased durability & service intervals
The crankcases are designed to house the shaft arrangements and internals of the engine in the position that offers the best possible handling.
Additionally, the position of the clutch shaft keeps the clutch above the oil level resulting in decreased friction and increased efficiency. High-pressure die cast production processes keep the overall weight to a minimum, resulting in thin wall thickness while retaining reliability.
=>Design → optimised mass-centralisation, increased efficiency
=>High pressure die cast production process → thin walls for reduced weight, while maintaining strength
The lightweight 5-speed gearbox is produced by Pankl Racing Systems ensuring the highest level of durability and reliability. The gear lever features a design that prevents dirt build-up and makes the lever tip in its original position even in the toughest conditions. An advanced gear sensor selects a specific engine map tailored for each gear.
=>5-speed gearbox → smooth & precise shifting
=>Integrated gear sensor → specific engine maps for each gear
The FC 450 features a DDS (Dampened Diaphragm Steel) clutch. The exclusive characteristics of this system include a single diaphragm steel pressure plate instead of traditional coil springs. It integrates a damping system for better traction and durability. The clutch basket is a single-piece CNC machined steel component that allows the use of thin steel liners and contributes to the compact design of the engine.
=>DDS clutch → lighter, with better action & advanced durability
