01. Titanic power
Engine
The most powerful engine in the Husqvarna Motorcycles FEs line-up, the 510.9 cc power plant is more advanced than ever while only weighing 64.8 lbs. Delivering colossal performance in all conditions, the FE 501s power is controlled with a lightweight 6-speed transmission and DDS (Dampened Diaphragm Steel) clutch.
Cylinder head
The SOHC cylinder head is incredibly compact and lightweight using a short profile with the camshaft located as close to the center of gravity as possible, significantly improving handling and agility. The lightweight valves are actauted via a rocker arm and feature timing specifically designed to deliver precise levels of torque and throttle response. 40 mm titanium intake valves, 33 mm steel exhaust valves and low-friction DLC coating on the rocker arm and shorter low-friction chain guides offer the optimum efficiency and reliability.
Crankcase
The crankcases are designed to house the shaft arrangements and internals of the engine in the best possible position, centralizing masses for a lightweight handling feel. High-pressure die cast production processes result in a thin but reliable wall thickness and keeping weight to a minimum.
Cylinder and piston
The lightweight aluminium cylinder features a 95 mm bore and a lightweight Konig forged bridge-box-type piston. This is perfectly matched to the high compression combustion chamber, producing very little oscillating mass. The high compression ratio of 12.75:1 reduces vibration and engine knocking, further increasing rider control and comfort.
