2026 KTM 450 Factory Edition Baseline Settings

The new KTM 450 SX-F Factory Edition comes with WP’s Pro Components and although we finally got a spring fork in standard trim (thank you KTM), the CV fork is a little firm through the mid stroke which can make the KTM feel very harsh on edge of tire (while leaning). The Traxx shock can…
