The Husqvarna FE 501 is a powerhouse of an enduro bike, boasting the most potent engine in the Husqvarna range. With a 510.4 cc power plant weighing in at just 64.8 lbs, this bike delivers colossal performance in any condition, thanks in part to its lightweight 6-speed transmission and DDS clutch.
A key highlight of the FE 501 is its ability to minimize vibration, thanks to a counter balancer shaft and a compact SOHC cylinder head that’s been redesigned to be 15 mm lower and 500 g lighter. This not only improves handling but also enhances bottom-end performance and responsiveness.
The FE 501’s engine is a masterclass in weight reduction and optimized efficiency, with improvements to the cylinder and piston setup, including a new lightweight aluminum cylinder and a Konig forged bridge-box-type piston. This combination produces remarkably little oscillating mass, significantly reducing vibration and increasing rider comfort.
The FE 501 is a testament to Husqvarna’s commitment to quality and craftsmanship, with high-quality finishes and premium components throughout. Whether you’re carving through tight trails or tackling the toughest terrain, the Husqvarna FE 501 is an enduro bike that’s sure to leave you grinning from ear to ear, and always ready to tackle the next adventure.
