2020 FS 450 Supermoto - Pros & Cons
Strengths
-
🛑
Strong front braking: The disc front brake gives excellent stopping power and responds well to aftermarket braided lines.
Considerations
-
📏
Tall seat height: The 927 mm seat height will challenge shorter riders - tiptoeing at low speeds is something to factor into your decision.
-
⛽
Modest fuel capacity: The 9.5-litre tank means more frequent fuel stops on longer rides, which is worth planning around on touring routes.
-
⚙️
Chain final drive upkeep: Chain final drive needs regular cleaning, lubrication and tension checks to get full life out of the sprockets.
Wear Points & Servicing Notes
Cooling system servicing
The Liquid cooled system on the FS 450 Supermoto needs a coolant change roughly every two years (or per the service schedule) - skipping it lets the coolant turn acidic and corrode the aluminium water passages over time.
Brake disc and pad wear
The disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the FS 450 Supermoto runs WP-USD, AER 48, ø 48 mm and WP shock absorber with linkage at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by chain - expect to clean and lube it every few hundred kilometres and check tension regularly; a neglected chain wears the sprockets faster than the chain itself.
Frame & chassis check
The frame is Design Chrome-molybdenum steel tubular space frame, powder-coated - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Low-speed handling
At just 110 kg, the FS 450 Supermoto is light enough to manhandle easily at a standstill - one of the practical advantages of its class.
FS 450 Supermoto - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2020 Husqvarna FS 450 Supermoto with its 449 cc super motard, start with the basics: check the service book for oil change frequency, inspect the drivetrain for wear, and look for oil seepage around the engine casings and rocker covers. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 6 years old, this super motard is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. A cold start test is invaluable - a well-maintained FS 450 Supermoto should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task for the FS 450 Supermoto's 449 cc four stroke, single cylinder, dohc, 4 vlave. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Carburetor upkeep
Keep the carburetors clean and free of deposits. If the FS 450 Supermoto has been stored, strip and clean the carb float bowls before attempting to start it. Pilot jets are the first to block and the last to be checked - always include them in any carb rebuild.
