2011 Husaberg FE390 Torque Specs: Enduro Competition Fastener Guide
Shop parts for a 2011 Husaberg FE390 Dirt Bike.
The 2011 Husaberg FE390 continues the competitive enduro lineage of the FE390 series with a refined 390cc single-cylinder four-stroke in Husaberg's distinctive forward-inclined chassis. The 2011 model benefits from ongoing development of the platform, with suspension and engine calibration refined from the 2010 introduction. Torque specifications remain consistent with the prior year across all major fastener groups.
Drivetrain & Axle Torque
Rear axle alignment is a critical setup parameter on any enduro machine, and the FE390's chain adjuster system requires correct lock nut torque to hold alignment through a full day of competitive use. Always measure alignment from both sides of the swingarm with reference marks before locking the adjusters.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front axle nut | 36–43 | 49–58 |
| Rear axle nut | 47–54 | 64–73 |
| Rear sprocket bolts | 22–29 | 30–39 |
| Chain adjuster lock nuts | 18–22 | 24–30 |
Engine Torque Values
The 2011 FE390's engine internals received calibration updates from the 2010 model, though the torque specifications for external fasteners remain the same. Oil changes remain the most frequent maintenance task—replace the drain bolt sealing washer at every change to protect the aluminum case boss from repeated torque cycles against a deformed washer.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Spark plug | 15–18 | 20–25 |
| Oil drain bolt | 18–22 | 24–30 |
| Cylinder head bolts (8mm) | 18–22 | 24–30 |
| Cylinder head bolts (10mm) | 33–37 | 45–50 |
| Cylinder base nuts | 18–22 | 24–30 |
| Flywheel nut | 47–54 | 64–73 |
| Clutch hub nut | 47–54 | 64–73 |
Suspension & Chassis
The 2011 FE390's WP suspension settings were revised for improved traction on loose enduro terrain. Fork clamp torque should be consistent across both legs—check both the upper and lower clamp bolts on each fork to confirm even seating before every competition day.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Fork clamp bolts — upper triple clamp | 11–15 | 15–20 |
| Fork clamp bolts — lower triple clamp | 15–19 | 20–26 |
| Handlebar clamp bolts | 18–22 | 24–30 |
| Swingarm pivot bolt | 54–61 | 73–83 |
| Rear shock upper mount | 29–36 | 39–49 |
| Rear shock lower mount | 29–36 | 39–49 |
| Shock linkage bolts | 29–36 | 39–49 |
Brake Hardware
Brake system reliability on the 2011 FE390 depends on thread locker on all disc bolts at every reassembly. A post-event brake inspection should be part of every competition routine: check disc bolt torque, caliper bracket torque, and brake fluid level before the next outing.
| Fastener | Torque (ft-lb) | Torque (Nm) |
|---|---|---|
| Front caliper mounting bolts | 18–22 | 24–30 |
| Front brake disc bolts | 14–17 | 19–23 |
| Rear caliper mounting bolts | 18–22 | 24–30 |
| Rear brake disc bolts | 14–17 | 19–23 |
