KTM unveils KTM 450 SX-F Factory Edition available from the end of December in the USA in limited numbers. 

The USA-specific 450 SX-F Factory Edition is a saucy bundle of KTM goodness and we know attracts plenty of interest from enduro riders — it’d sure look good with a set of lights.

Here’s the low-down…

The 2018 KTM 450 SX-F Factory Edition features Red Bull KTM Factory Racing graphics, orange anodised triple clamps, Hinson factory clutch cover, D.I.D Dirt Star rims, factory Selle Dalla Valle seat, floating front disc. 

The SX-F 450 is updated for 2018 with a host of differences over the EXC models, making it a sharper, punchier and stiffer handling bike favoured by many for faster enduro racing. 

“We have been working closely with our R&D departments in both the USA and Austria to develop the KTM 450 SX-F Factory Edition, which will be contested by our racers in the 450 class under the homologation rule, and has some key revisions for MY2018,” told KTM Team Manager Roger DeCoster at the bikes USA launch.

A whole lot of new

The 2018 model boasts new bodywork, a revised chassis, new suspension settings with a new triple clamp design, an improved cooling system with new radiators, exhaust and a revised engine with a more compact cylinder head offering improved power-delivery. 

The 2018 WP AER front forks feature a new air seal, air piston and rebound spring on the air leg, plus a new piston on the damping side. They’re re-valved for increased low-speed compression and slightly less high-speed compression thanks to slightly bigger mid-valve shims. 

The SX-F model’s five-speed transmission is another strong call for enduro racers wanting its punchy nature more than that long top gear on the EXC. The shaft bearing and shift star are stronger for 2018 and better withstand the high engine temps.

Two engine power maps and launch control feature as standard on the 450 SX-F plus it now uses the more powerful battery from the XC and EXC models to help starting performance.
