KTM has pulled the wraps off its 2018 KTM 450 SX-F Factory Edition ahead of the new AMA Supercross season, set to be entered by the Red Bull KTM Factory Racing and Rocky Mountain ATV/MC WPS KTM teams.

Expected to form the basis of KTM’s 2019 production models, the limited 2018 Factory Edition boasts a reworked chassis with new bodywork, an updated engine and new suspension settings, plus an updated triple-clamp. According to KTM, the bodywork is slimmer and the seat has been redesigned.

The frame features an increase in torsional rigidity for improved bump absorption, stability and rider feedback. A new aluminium sub-frame is 40mm longer for a stiffer rear section, while the orange powder-coated frame is fitted with colour-matching frame protectors and a carbon fiber reinforced skid plate. The swing-arm has a 5mm longer rear axle slot.

In terms of the suspension, the new WP DCC shock absorber has a new main piston and updated setting, paired with top-specification WP production forks that include a built-in holeshot device out of the crate.

KTM has revealed the engine is lighter and 15mm shorter in height, featuring a more compact revised cylinder-head, friction treatments on the cams and cam-chain. It has a new exhaust system, which enables the header to be removed without taking out the shock.

On top of the technical advancements, the 2018 KTM 450 SX-F Factory Edition has Red Bull KTM Factory Racing graphics, orange anodised triple clamps, a Hinson factory clutch cover, composite skid plate, D.I.D Dirt Star rims, Factory seat with Selle Dalla Valle logo, a floating front disc, front brake disc guard and orange rear sprocket.

At this stage however, KTM isn’t intending to bring the 2018 KTM 450 SX-F Factory Edition into Australia for the new year, as it’s been built as a US-only variant.
