We’re almost done installing the Andreani 39mm fork cartridges to our Harley Sportster. Follow along as we finish the job!
Italian superbikes are known for their incredible handling. One of the main reasons these bikes handle so well is the way the suspension is set up for each bike and its rider. Andreani has taken this state-of-the-art technology that is used in the superbike industry and came up with a drop-in, tunable cartridge kit for 39mm H-D forks for XL. The result is a responsive front end that reacts well when put to the test. We installed the cartridge kit in our “Little Devil” Sportster project and were quite happy with the results. Unlike other fork kits, the Andreani cartridge setup requires some special tools and general suspension knowledge to install properly.

Measure the required amount of fork oil that is recommended for your bike or application. We chose BelRay 10W fork oil at a level of 10.8 ounces.

Since we do not have the option of removing the top spring to put the fork oil in, we have to use a small funnel and pour the fork oil in slowly.

Screw the Andreani fork cartridge cap into the fork lower and tighten. Do not overtighten; if you do you will find removing the cartridges to be a pain.
