2001 to 2003 Husaberg FX450E FX650E Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Husaberg FX450E and FX650E are the cross competition focused variants of Husaberg 4 stroke enduro lineup produced from 2001 through 2003. The FX designation identifies these machines as cross competition oriented models, built for performance rather than dual sport use. Husaberg, originally from Sweden and later integrated into the KTM Group, was one of the pioneering European manufacturers to develop competitive 4 stroke enduro motorcycles.
Both models are built around Husaberg signature single cylinder 4 stroke engine with its distinctive forward tilted cylinder layout. This design innovation positions the engine at approximately 60 degrees from vertical, lowering the center of gravity and concentrating mass near the motorcycle center. The FX450E produces approximately 400 cc and the FX650E delivers around 650 cc of displacement, both providing strong torque that is characteristics of 4 stroke single cylinder design.
The FX models feature competition grade components throughout including WP suspension, Brembo brakes, and a lightweight chromoly trellis frame. These machines are built to withstand the rigors of cross country racing while remaining serviceable with standard hand tools, making them popular among privateer racers who perform their own maintenance.
