PERFORMANCE.
PRECISION.
PERSONALISATION.

After an extended period of testing and refinement by 12-times World Champion Dougie Lampkin and 2020 Trial125 World Champion Pau Martinez, Jitsie is hugely proud to launch the ADRF front fork. This long-term project has been led and benefited from the expertise of Appie Hens, who has more than twenty-five years-experience in suspension technology as the R+D leader at WP Suspension and Technical Touch (KYB).

Packed with factory level features, the fully adjustable fork legs allow for a truly custom set up to suit your own and unique riding style, irrespective of your personal level.

CNC MACHINED LOWER STANCHIONS.
JUST 4.4KG ALL IN.

Weighing just 4.4kg the Jitsie ADRF forks boast 170mm of travel and feature Ø39mm hard anodised high-grade aluminium Jitsie branded upper tubes that are perfectly matched with CNC machined aero-grade billet lower fork stanchions. Stunning in external appearance it is inside where the real beauty lies with the lower right fork leg containing a cone that strongly increases the progressive damping during the last part of the stroke to eliminate ‘bottoming’.

EASY SETUP.
FOCUS ON PERFORMANCE.

External adjustment is both easy and accessible with the carefully designed top caps offering step-free fine tuning. Rebound damping and spring pre-load are controlled by the right top cap, whilst the left top cap allows alteration of the compression damping.

The forks are delivered standard with the following settings:

TOP QUALITY COMPONENTS.
CHOOSE YOUR SPRING.

The left fork leg damping system combines an open cartridge with a Ø20mm piston and Ø10mm rod, whilst the right fork leg contains a 370mm CrSi spring suitable for your weight and riding level. These core elements are complimented by SKF 39mm oil and dust seals, and Daido Teflon coated slide and guide bushes, which all combine to provide a super plush and stiction less stroke. Filled with Motul EXPERT M10W fork oil, all internal aluminium cartridge components are hard anodised to prevent fluid contamination.
