2021 KTM 450 SX-F [Model Overview]

The 2021 KTM 450 SX-F: Championship Pedigree At Your Right Wrist

The 2021 KTM 450 SX-F is the championship-winning bike from the Austrian company that has won year after year of 450cc class four-stroke motocross and supercross. It has a lightweight alloy frame cradling 450cc’s of raw four-stroke power, which equates to just over 63 HP.

KTM seems to have the formula to success, as the 450 SX-F only weighs 2.5 pounds more than the 350 SX-F, which in and of itself was a super light bike. Electronic fuel injection, a single overhead camshaft, and some very tricky valve management allow the engine to be the lightest in its class, while also being one of the most powerful in the 2021 lineup.

WP suspension is standard, of course. Brembo brakes and hydraulics are also par for the course. The biggest change the 450 SX-F sees is that its front brake is a whopping 260mm disc, compared to the 220 to 230 mm discs on lower spec models.

There is also a 450 SX-F Factory Edition, which adds an Akrapovič titanium exhaust, a racing connectivity unit to review laps, KTM factory competition wheels, a carbon-composite skid plate, a semi-floating front brake disc, and a full Red Bull Racing graphics kit. It also features the same Hinson clutch that the KTM Dakar Racing Team use on their 450 Enduro bikes, meaning endurance and race proven clutch feel.

The 2021 KTM 450 SX-F starts at $10,199 USD / $11,699 CAD, while the 450 SX-F Factory Edition starts at $11,299 USD / $13,099 CAD.
