Product Description
The Dal Soggio SPHERE 3.0 WP 48 XACT CC MX US Cartridge Kit is a high-performance suspension upgrade developed specifically for the WP 48 XACT Closed Cartridge spring fork platform used on compatible KTM and Husqvarna off-road competition motorcycles for the US market.
Dal Soggio officially identifies SKU 1P.SPH.XACT-CCMX3.0 as Sphere 3.0 – WP 48 XACT CC 2024-2026 MX – US models.
For North American motorcycles, this Closed Cartridge spring-fork configuration is particularly relevant to the KTM XC / XC-F and Husqvarna TX / FX Cross Country families rather than the standard SX/SX-F and TC/FC motocross models equipped with WP XACT AER air forks.
SPHERE 3.0 replaces the original internal damping arrangement with Dal Soggio Race’s sealed and pressurized hydraulic cartridge, developed through extensive dyno and track testing to increase fork sensitivity, precision, hydraulic control, and rider feedback.
One of the major SPHERE 3.0 developments is the redesigned bladder, featuring a thinner yet stronger construction. This improves cartridge sensitivity and allows more precise hydraulic bleeding.
The redesigned compression base valve features separate High-Speed Compression and Low-Speed Compression settings. Each damping range can therefore be modified independently, giving suspension technicians greater freedom to tune the fork according to rider weight, riding style, speed, and terrain.
SPHERE 3.0 also uses a larger 36 mm compression piston, replacing the 28 mm piston of the previous generation. The larger working diameter is designed to improve the linearity of the fork’s hydraulic response throughout the suspension stroke.
Another key innovation is Dal Soggio’s Direct Flow Technology. Oil reaches the compression piston directly rather than passing through the previous Z-shaped internal passages, helping reduce unnecessary hydraulic restriction and cartridge stress.
This WP XACT CC version also uses Dal Soggio’s Quick Install System. On compatible WP XACT platforms from 2024 onward, installation does not require removal of the inner fork tube from the axle lug, simplifying the mechanical installation procedure.
Dal Soggio specifies CUBE Fork Oil 5W for use inside the SPHERE hydraulic cartridge system.

Application & Compatibility
The 1P.SPH.XACT-CCMX3.0 SPHERE 3.0 is designed for compatible WP 48 XACT Closed Cartridge spring forks used on KTM and Husqvarna US-market off-road competition motorcycles.
Dal Soggio’s dedicated product page identifies this version as:
WP 48 XACT CC – KTM / Husqvarna – MX / US Models – 2024-2026.
On the North American platform, the relevant motorcycles are primarily the KTM XC / XC-F and Husqvarna TX / FX Cross Country models equipped with the WP XACT 48 mm Closed Cartridge spring fork.
This distinction is important because the standard KTM SX/SX-F and Husqvarna TC/FC motocross families use a different WP XACT AER air-fork architecture and should not automatically be considered compatible.
This version should also not be confused with:
- 1P.SPH.XACT-CCEN3.0 – WP 48 XACT CC Enduro version;
- 1P.SPH.XACT2125MX3.0 – earlier WP XACT MX configuration;
- WP XACT AER-specific SPHERE applications.
Hydraulic System & Performance
SPHERE 3.0 replaces the original fork damping internals with a sealed and pressurized cartridge engineered to provide increased sensitivity, precision, and tuning flexibility.
The redesigned bladder improves cartridge response and bleeding precision.
The 36 mm compression piston provides a larger working diameter than the previous 28 mm design, contributing to a more linear hydraulic response.
Separate High-Speed and Low-Speed Compression circuits allow slower chassis movements to be tuned independently from faster suspension impacts.
With Direct Flow Technology, oil reaches the compression piston directly, avoiding the previous indirect internal routing and reducing hydraulic restriction.
Cross Country / Competition Application
US Cross Country racing combines elements of motocross, Enduro, and high-speed off-road competition.
The front suspension must therefore handle:
- braking bumps;
- roots and rocks;
- high-speed chop;
- square-edge impacts;
- jumps and hard landings;
- ruts and technical terrain;
- repeated high-load suspension movements.
The separate compression circuits allow the suspension technician to tailor chassis support and impact absorption independently, providing a broad setup range for different types of terrain and rider requirements.
Quick Install System
This SPHERE 3.0 version incorporates Dal Soggio’s Quick Install System for compatible WP XACT platforms from 2024 onward.
Installation no longer requires removal of the inner fork tube from the axle lug, simplifying the mechanical procedure.
Professional installation remains strongly recommended because correct cartridge bleeding, oil quantity, spring setup, and damping calibration are critical to suspension performance and safety.
Oil & Service
Dal Soggio specifies CUBE Fork Oil 5W for the SPHERE hydraulic cartridge system.
Correct oil quantity, cartridge bleeding, spring selection, damping adjustment, and overall chassis balance are essential for proper operation.
Professional installation and setup by a qualified off-road suspension specialist are recommended.
Installation Note
Before installation, confirm:
- WP 48 XACT Closed Cartridge spring fork;
- compatible US-market KTM or Husqvarna motorcycle;
- applicable model year within the supported platform generation;
- Cross / Cross Country configuration;
- correct Dal Soggio SKU 1P.SPH.XACT-CCMX3.0.
Do not determine compatibility only from motorcycle brand or model year. The actual front fork fitted to the motorcycle should always be identified before ordering.
