Husqvarna FS450 supermoto updated for 2019

The Husqvarna FS450 supermoto is getting a whole host of updates for 2019.

As you usually see in the dirt bike world, the FS450 gets a host of minor upgrades but no major game-breaking changes.

Engine changes included a revised cylinder head (half a kg lighter). updated cooling system and revised Magura hydraulic clutch with a Suter anti-hop system. The exhaust’s resonance chamber has been revised to promote better flow, and Husqvarna included a more compact silencer.

The suspension has been revised, with new settings on the WP AER forks’ the rear shock (also from WP) gets a new piston and updated settings as well.

The brakes are new high-performance Brembo units, and the traction and launch control are updated as well

The frame has a new blue coating, and the subframe has a new two-piece design that reduces a bit of weight too.

The previous FS450 model was brought in for offroad-only usage, and this model will also likely be the same, although enterprising owners could no doubt finagle their way to a street-legal plate.

  1. Could you please elaborate on – “enterprising owners could no doubt finagle their way to a street-legal plate.”

    Is this actually possible? In BC, for example?

    • It comes down to province-by-province what the DMV will allow. And, in my experience, that even varies from DMV location to location. I personally got a street-legal plate for a motorcycle imported as offroad only (2006 Lifan GY-5), and here in New Brunswick, I know it’s still possible to do so, as long as you meet the requirements for a street bike (proper lighting, etc) and sometimes they also make an engineer sign off on it.
