Heads Up: Every Engine Ships as the KTM Version

Whichever brand you ride, your engine arrives with KTM covers, which is why the part number and listing say KTM. 2023–2027 KTM, Husqvarna and GASGAS motocross bikes of the same size share the same core engine, so mounting points, output shaft and internals line up exactly.

Any difference is cosmetic. Expect a KTM-branded clutch cover in place of your Husqvarna or GASGAS cover. Want it to match? Add the OEM cover for your brand.

Older than 2023? Call 772-426-3000 to confirm fitment first.

Engine FAQ

Fitment question not covered here? Call 772-426-3000 or email info@wmr1.com.

Which engine fits my bike?

Each engine fits 2023–2027 models across all three brands. 250: KTM 250 SX-F, Husqvarna FC 250, GASGAS MC 250F. 350: KTM 350 SX-F, Husqvarna FC 350, GASGAS MC 350F (built 2023–2025). 450: KTM 450 SX-F, Husqvarna FC 450, GASGAS MC 450F.

Why does the part number say KTM?

Every engine ships with KTM covers, so it carries the KTM part number. Mounts, output shaft and internals are the same across KTM, Husqvarna and GASGAS; the only visible difference is the KTM-branded clutch cover.

Can I get a Husqvarna or GASGAS clutch cover?

Yes. Add the OEM Husqvarna outer clutch cover (A48030626000JA) or GASGAS outer clutch cover (A49030126000), plus a new outer clutch cover gasket (A48030027000). The cover bolts on in place of the KTM one. Want billet? The Hinson factory clutch cover (A48030926000) fits KTM and Husqvarna, and the Hinson GASGAS cover (A59030926000) fits 2024 and newer GASGAS MC.

Will it fit a bike older than 2023?

These engines are listed for 2023–2027 models. For anything older, call 772-426-3000 or email info@wmr1.com before ordering.

Is there a core charge?

No. No core is required, so you keep your old engine.

Will an SX-F engine fit an XC-F or EXC-F?

These are motocross engines for SX-F, FC and MC models. XC-F and EXC-F models can use different gearboxes and internals, so call before ordering.
