2001 to 2003 Husaberg FS400E FS650E Service Repair Workshop Manual PDF
VEHICLE/EQUIPMENT INTRODUCTION:
The Husaberg FS400E and FS650E are enduro motorcycles manufactured by Husaberg, a Swedish brand that merged with KTM in the late 1990s. The E designation identifies these as four stroke single cylinder machines, representing Husaberg early push into 4 stroke enduro technology. The FS models are street legal enduro versions designed for dual sport riding combining off road capability with road registration compliance.
Powering these models is a vertically mounted single cylinder 4 stroke engine with the FS400E displacing approximately 400 cc and the FS650E delivering around 650 cc. The unique Husaberg design features the cylinder tilted forward approximately 60 degrees from vertical with the fuel tank positioned beneath the seat for centralized mass distribution and improved handling on rough terrain.
Husaberg motorcycles have competed at the highest levels of enduro competition and the FS models are street legal variants of their pure competition machines. The chassis features a chrome molybdenum steel trellis frame long travel WP suspension and Brembo brakes providing excellent performance on both trails and paved roads.
