Husqvarna announced a revised FS450 supermoto for 2017, updated with air forks and traction control. The 2017 model is currently listed on Husqvarna’s U.S. site but U.S. pricing and availability is still to be confirmed.

The engine remains the same 450cc Single that powered the previous model, but with lighter aluminum engine engine mounts. The Keihin Engine Management System was updated to add traction control. Husqvarna also updated the handlebar switchgear to make it easier to select between the two engine maps and activate launch control and traction control systems.


As it did for its 2017 off-road lineup, Husqvarna swapped out the previous model’s 48mm closed-cartridge fork with WP’s new air fork. The AER 48 fork uses an insulated air chamber in the left tube, adjustable via the included air pump, while the right tube houses a hydraulic damping unit. Husqvarna claims a weight reduction of 3.7-pounds just from switching to the AER fork. Husqvarna also added a new CNC-machined triple clamp designed to meet the new suspension’s characteristics.

The cast aluminum swingarm is connected to a WP DCC rear shock specifically tuned for supermoto racing.


WP also produced the FS450’s hydro-formed chromium-molybdenum frame which is matched to a composite subframe made of 30% carbon fiber claimed to weigh just 3.1 pounds.

The 16.5-inch front and 17-inch rear Alpina spoke wheels allow for tubeless tires, with the FS450 coming with slick Bridgestone 125/80 R420 and 165/65 R420 tires. Both wheels are stopped by Brembo brakes: a four-piston radial-mount caliper up front and a single-piston floating caliper at the rear.

Other features include an APTC slipper clutch, 1.8-gallon polythene fuel tank  ProTaper handlebars and, of course, bold new graphics.
