2018 Husqvarna FC450
The SOHC engine is the perfect example of the advanced engineering techniques used by Husqvarna Motorcycles. It offers a peak power of 63 hp at an overall weight of just 27.8 kg. Mass-centralisation is key in the engine design, enabling chassis engineers to position the engine closer to the centre of gravity for greatly improved handling and manoeuvrability.
The compact SOHC cylinder head has been designed to offer the maximum performance at the minimum possible weight. The camshaft actuates four lightweight titanium valves that weigh only 32 g on the intake side and 28 g on the exhaust. The diameter of the intake valves is 40 mm, while on the exhaust it is 33 mm. Low-friction DLC coating on the rocker arm and low-friction chain guides offer optimum efficiency and reliability.
SOHC → compact engine design
Titanium valves → low weight, only 32 g on intake and 28 g on exhaust
DLC coating & optimised chain guides → reduced friction
Cylinder and piston
The lightweight aluminium cylinder is an engineering masterpiece. Featuring 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 amazing peak output of 63 hp.
The inertia produced by the crankshaft is carefully calculated to deliver optimal traction and ride-ability from the powerful 450cc plant. The crankshaft is specifically positioned to harness the rotating mass in the ideal centre of gravity, resulting in a lightweight and agile handling feel. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 100 hours.
Crankshaft position → ideal centre of gravity, improved handling
Plain big end bearing and force-fitted bearing shells → increased durability and 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. The historic Husqvarna logo adorns the bronze finished crankcase covers.

High pressure die cast production process → thin walls for reduced weight, while maintaining strength
The lightweight 5-speed gearbox has a low-friction coating on the shifting fork guaranteeing smooth and precise shifting. The gear lever features a design that prevents dirt build-up and keeps the lever tip in its original position even in the toughest conditions. An advanced gear sensor allows for specific engine maps in 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.
