More power than you'll ever be able to use - but smooth, confidence-inspiring and ride-able enough that you could quite realistically try. The 2017 FE 501's brand-new 1.7 kg lighter engine is the most powerful in the Husqvarna enduro line-up. Class leading electronics to adjust the 510.4 cc power plant's delivery while the single overhead camshaft (SOHC) cylinder-head is designed for maximum performance with minimum weight. A new camshaft actuates four lightweight valves, while more stream-lined chain guides increase efficiency and performance. The new compact crankshaft increases inertia without increasing weight, while the new big-end bearing design increases reliability and durability, for long service intervals of 135 hours.
Featuring the latest technology, the FE 501 engine is fully redesigned for MY17. With increased performance, smaller dimensions and a weight saving of 1.7kg as well as a revised cylinder head and class-leading electronics, the 510.4cc power plant is more advanced while weighing only 30.1kg
The compact SOHC cylinder head is designed to offer the maximum performance at the minimum possible weight. The new camshaft actuates four lightweight valves (titanium intake Ø=40mm 32,6g, steel exhaust Ø=33mm 42,6g) through a very robust rocker arm system. Additionally, the timing drive is revised with a new, shorter timing chain and friction optimised chain guides which reduce drag and increase efficiency and performance. Overall the more compact design is now 350g lighter.
The crankcase is designed to house the shaft arrangements and internals of the engine in a position that offers the best possible centre of gravity. This is achieved by moving the crankshaft 7mm higher and 9mm backwards significantly improving mass centralisation and handling agility.
The new crankshaft offers 5% added inertia without increasing weight. Additionally, a shorter connecting rod and new crankshaft position improve mass centralisation and contribute to the compact design. A plain big end bearing comprising of two force-fitted bearing shells ensure maximum reliability and durability, guaranteeing long service intervals of 135 hours.
