2017 Husaberg FE 501

The FE 501 ranks undisputedly among the most powerful enduro machines in its class - developed by professionals for professionals. The combination of lightweight chassis and high-tech, SOHC four-stroke technology is the right choice for all those in the E3 class seeking maximum 4-stroke performance combined with playful handling. These powerhouses are regarded without doubt as the benchmarks in their classes.

Features may include:

• Cooling system

The tried and tested, integrated cooling system leads from the cylinder head through the frame triangle directly to the aluminium radiators made by WP RADIATOR. All 4-stroke models are equipped as standard with a fan system that has been improved with an optimised thermoswitch.

• Engine

Developed for tough enduro use, the 510.4cc SOHC engine is characterised by an extremely compact design, easy maintenance and outstanding robustness, with weight kept to a minimum. Together with the EFI system from Keihin, they provide unrivalled performance and rideability - specially designed for enduro use.

• Cylinder head

The SOHC cylinder head is equipped with an overhead camshaft that actuates the titanium intake valves and steel exhaust valves. The whole configuration has been perfectly tuned to the Keihin EFI system for outstanding rideability and performance. A weight-optimised valve train results in lower friction, thereby improving performance and reducing engine braking. An optimised cylinder head gasket guarantees even greater durability in extreme conditions. A weight-optimised camshaft with strengthened auto-decompressor ensures better responsiveness as well as greater durability.

• Pistons

The lightweight, forged piston with a diameter of 95 mm and box-type design is now equipped with a new, high-performance piston ring package.

• Crank drive

With 72 mm stroke for the 450, the crankshaft and its ultra-light connecting rod are manufactured by Pankl from a special, high quality steel. As on all other FE models, the revolutionary plain bearing in the lower conrod eye is now also employed here, guaranteeing considerably greater durability and hence much less servicing.

• Engine management system (EMS)

The engine management system from Keihin with electronic fuel injection and 42 mm throttle body ensures spontaneous, powerful responsiveness and handling, along with maximum performance. Automatic temperature and altitude compensation are state of the art. An oil-cooled, 196 W alternator provides sufficient power for the fuel injection system, lights, etc. An optional map-select switch and the user-setting tool are available from the PowerParts range.

• Transmission

The tried-and-tested 6-speed transmission excels with precise and easy shifting.

• DDS clutch

The one-piece outer clutch hub with primary gear is machined from a single piece of high-strength steel. This guarantees unbeatable reliability and contributes to narrow engine width with its compact, rivetless design. It also allows the use of thin steel discs, making the overall clutch package very compact. An optimised inner clutch hub improves the durability as well. A diaphragm spring enables implementation of an additional hub damping mechanism - a benefit in terms of traction and gearbox durability. In conjunction with the diaphragm spring, the hydraulic clutch actuation system from Brembo ensures very smooth and very precise clutch control.

• Starter

The FE 500 is equipped as standard with both kick and electric starters. Positioned behind the cylinder, the electric starter is well protected. It is prepared for the fitting of a kickstarter.
