2014 KTM 450 SX-F Factory Edition, 2014 KTM 450 SX-F Factory Edition KTM turned the model year concept a bit upside down a couple years ago, when they first introduced their Factory Edition models. That allowed them to bring their latest updates to each race season, by building enough models to satisfy the AMAs homologation rules. This time around we focused on chassis improvements, new suspension components, and once again, trimming weight. Since they first introduced the bike in 2012, they claim a total weight savings of five pounds, with nearly a pound-and-a-half of that coming this year.
