2019 Husqvarna FS 450 Supermoto Preview & Specs
The Husqvarna FS 450 Supermoto – a true OEM racer based on its FC 450 Motocross brother – has once again been updated.
The first major changes occurred in 2016 when the Swedish brand cut some weight, and then for 2018 when Husky upgraded the 450cc engine with a Suter slipper clutch and new map switch controls.
The updates continue for the 2019 Husqvarna FS 450 Supermoto, which sees major improvements in both chassis and engine updates.
1. The 2019 Husqvarna FS 450’s frame – now coated blue – was stiffened for improved rider feedback and straight-line stability. Out back, the composite carbon-fiber subframe’s weight was reduced by 0.6 pounds.
2. The 449.9cc single-cylinder four-stroke engine was updated with a redesigned cylinder head that further reduces weight and provides a more compact package. The engine, which produces 63 horsepower, loses a pound, and now weighs 60.2 pounds.
3. With all these weight changes, the 2019 Husqvarna FS 450 now weighs 226.9 pounds dry (without fuel in the 1.85-gallon tank). This is four pounds lighter than the 2018 FS 450 model.
4. The 2019 FS 450 is equipped with WP’s 48mm AER air fork and a WP DCC rear shock. The entire WP suspension package receives setting updates to match the updated frame rigidity. Husqvarna also says that the 16mm offset CNC machined triple clamps are specifically designed to work in harmony with the front forks.
6. The bodywork and ergonomics were slightly tweaked to match the updated handling and engine changes.
7. The 2019 Husqvarna FS 450 will arrive in dealers this September. US pricing has yet to be set, but expect to pay around $10,500 MSRP.
