2018 KTM 450 SX-F Factory Edition First Look | 9 Fast Facts

Inside The 2018 KTM 450 SX-F Factory Edition

Every year one of the most eagerly anticipated motocross motorcycles is the Factory Edition of the KTM 450 SX-F. KTM delays the release of the Factory Edition until the last moment—just a month ahead of Anaheim 1—so the bike can get the benefit of additional months of R&D.

Ready for Supercross and Motocross, the 2018 KTM 450 SX-F Factory Edition does not disappoint. Let’s look at what KTM did to the 450 SX-F to create the Factory Edition that will be campaigned by Marvin Musquin, Broc Tickle, Blake Baggett, Benny Bloss, and others.

2018 KTM 450 SX-F Factory Edition horsepower1. The motor is significantly updated from the standard 2018 KTM 450 SX-F. The changes are not minor—the top end is completely different—it’s shorter and has more direct flow into and out of the combustion chamber. The transmission is also beefed up and made by Pankl, a company owned by the same holding company that owns KTM. Also, the clutch is now a DDS (Damped Diaphragm Steel) design that eschews traditional coil springs.

2. The exhaust is also changed to complement the different power characteristics. The muffler is shorter to reduce weight far from the center of gravity. The header pipe gets a new resonance chamber. For easier maintenance, it is no longer necessary to remove the shock to detach the header from the motorcycle.

3. The 2018 KTM 450 SX-F Factory Edition gets an improved front end. In addition to new settings for WP suspension, the Factory Edition has a more robust triple clamp and a change in frame rigidity. The front disc is floating, rather than having a fixed mounting, and has a guard.

4. The bodywork and seat are changed. The bodywork makes it easier to move around on the Factory Edition, while the Factory ribbed seat features a Selle Dalla Valle logo. The bodywork also gets Red Bull KTM Factory Racing graphics. Underneath the seat is a longer subframe to stiffen the rear of the motorcycle.

6. The wheels are stronger. Professional supercross and motocross racers pound wheels hard, and the 2018 KTM 450 SX-F Factory Edition gets highly regarded D.I.D. DirtStar rims. There is also an additional five millimeters of rear wheel adjustment.

7. A composite skid plate protects the 2018 KTM 450 SX-F Factory Edition engine. It also makes the bike slipperier over obstacles, and when coming up short on double and triple jumps.

9. The price of the 2018 KTM 450 SX-F Factory Edition has not yet been set.
