MXA TEAM TESTED: DAL SOGGIO FSR-48 COMPLETE FORK
30/04/2024 18:30
WHAT IS IT? The Dal Soggio FSR-48 fork was designed and built in Italy by Mr. Gianni Dal Soggio as their top-of-the-line replacement for the WP forks on KTM, Husky and GasGas models, and the Sachs fork on the Beta off-road models. The FSR-48 fork features Sphere hydraulic closed-cartridge internals, which can be purchased separately from InnTeck USA as a drop-in kit.
WHAT’S IT COST? $3999.99 (valved and sprung).

WHAT STANDS OUT? Here’s a list of things that stand out with the Dal Soggio FSR-48 complete fork.
(1) Backstory. Dal Soggio was established in Italy where they instituted a “Race Part Division” to build the finest suspension components available. InnTeck USA is now the distributor for Dal Soggio suspension in the U.S. They also carry SKF seals, Mr. Wolf Mousse balls and more.
(2) Concept. Dal Soggio sells a Sphere Hydraulic Cartridge spring conversion kit which retails for $1539 and gives you 95 percent of the performance without the billet lugs, beefy stanchions and premium coatings that come with these complete forks. Of course, the last 5 percent of performance doesn’t come cheap.
(3) WP History. Ten years ago WP offered a coil-spring bladder fork. It was replaced by the much-hated 4CS spring fork, and in 2017, WP introduced its original AER air fork. We bring up the WP forks’ history since it’s relevant to the Dal Soggio FSR-48 fork—because the Dal Soggio’s Sphere hydraulic closed-cartridge drop-in kit uses a bladder as well.
The MXA test riders who raced with WP’s bladder fork back in the day, also believed that those forks had the most potential of any of WP’s coil-spring forks—even if they didn’t live up to its orginal promise. A bladder fork uses a floating piston to help promote a plush feel on the track while pressurizing the inner chamber to keep the air from mixing with the fork oil. The one downside to the WP bladder fork was that it required service more often.
(4) Performance. We were shocked that our test set of FSR-48 forks came valved from the Dal Soggio factory, and we never had to touch them. Their “base setting” was right on target for our 2024 KTM 450SXF. It’s not often we take a fork out of the box and race it as is.
The MXA test riders were blown away by the performance of the Dal Soggio FSR-48 forks. We liked them so much that test riders moved them from bike to bike to benefit from their ultra-plush feel. The FSR-48s spent time on our 2024 KTM 250SXF, Husqvarna FC250, KTM 450SXF and Husqvarna FC450. Comparing the Dal Soggio forks to the stock WP XACT air forks, our pickiest testers noticed the added weight of the spring forks, but believed the plushness at the top of the stroke overrode that complaint.
WHAT’S THE SQUAWK? The all-black FSR-48s are ultra-cool looking, but the materials used are more important than how they look. Dal Soggio uses ultra-premium ERGAL 7075-T6 aluminum with hard anodizing and a DLC treatment. Our only complaint is that with the all-black look, the stanchion tubes show more roost pitting than stock gray fork tubes. The $3999.99 retail price may seem steep, but it’s well below all the other aftermarket fork options (plus the Sphere cartridge kit cuts the price in half).
MXA RATING: These are the most awesome aftermarket forks that we’ve come across in years. They were loved by our Pro, Vet and Novice test riders, regardless of weight or speed. We hope Dal Soggio never asks for them back!
