30 mm Cartridge Fork Kit

The Öhlins FKS 507 is a 30 mm cartridge fork kit designed to improve stability and damping performance on the KTM RC 390 (2017-2019) and KTM Duke 390 (2013-2019). This performance-oriented system provides adjustable compression damping and a compression adjuster on the left fork leg, while the right leg handles rebound damping and adjustment. Riders can make all settings, including spring preload, easily from the top of the fork cap. Buyers must verify the base of their fork for the correct bolt before ordering, as this kit is primarily for 2018 "base bolt" and later models, with limited compatibility for some 2017 units. Please be aware that this cartridge kit does not include fork springs or suspension oil; these components are sold separately and must be selected based on the driver's preferences. Professional installation or experience with fork assembly is recommended for proper setup.
