2023 KTM 450 XCF-W Horsepower and Torque

KTM’s 450 XCF-W stands by itself because the Austrian producer’s solely four-stroke enduro mannequin, no less than for 2023. It’s joined by two different headlight-equipped thumpers that aren’t street-legal for 2024—the 350 XW-F and 500 XW-F, however they’re tuned to be 50-state off-highway compliant. In contrast to them and the 350 EXC-F and 500 EXC-F twin sports activities, the 450 XCF-W doesn’t have a carbon canister for the gas system, sound-deadening reed system within the airbox, or choked-up muffler. It’s nonetheless KTM’s solely competition-focused four-stroke enduro mannequin in inventory trim.

As a brand new mannequin for 2023, this yr marks the primary time we’ve examined the 450 XCF-W and run it on our in-house Dynojet 250i rear-wheel dynamometer. With a Dunlop D404 road tire on the rear wheel, we documented 48.3 hp at 9,200 rpm and 31.9 lb.-ft. of torque at 7,400 rpm. These aren’t the very best numbers we’ve seen from a 450 filth bike, however the way in which the fuel-injected liquid-cooled SOHC four-stroke 450cc engine delivers that energy is what’s so spectacular. “The 450 XCF-W engine is just magic, and does nothing incorrect,” take a look at rider Allan Brown stated. “It builds energy from the bottom rpm and by no means stops with out ever being an excessive amount of to deal with.”
