SPHERE 3.0 WP 48 XACT CC MX Hydraulic Cartridge 2024-2026 US Models Dal Soggio **EXCLUDING 2024 SX AND TC**

The Dal Soggio 1P.SPH.WPXACT24MX3.0 SPHERE 3.0 is a complete sealed and pressurized hydraulic cartridge developed for compatible WP 48 XACT Closed Cartridge motocross forks used on selected KTM and Husqvarna US-market applications.

Dal Soggio’s current catalog identifies the corresponding configuration as 1P.SPH.XACT-CCMX3.0 – Sphere 3.0 WP 48 XACT CC 2024-2026 MX – US models.

This version is specifically developed for Cross / Motocross use and should be distinguished from the separate SPHERE 3.0 XACT Closed Cartridge Enduro version.

The SPHERE 3.0 architecture introduces a redesigned bladder, described by Dal Soggio as thinner and stronger than the previous generation. This change is intended to improve cartridge sensitivity and increase precision during hydraulic bleeding.

The compression base valve provides separate High-Speed Compression and Low-Speed Compression adjustment, allowing the two damping ranges to be tuned independently according to rider preference, track conditions, and suspension setup.

SPHERE 3.0 also increases the compression piston diameter from 28 mm to 36 mm, a change developed to improve the linearity of the complete front suspension.

The cartridge uses Direct Flow Technology, allowing suspension oil to reach the piston directly rather than travelling through Z-shaped internal passages. This creates a more direct hydraulic flow path and reduces stress within the cartridge.

For the WP XACT platform from 2024 onward, Dal Soggio also incorporates the Quick Install system, eliminating the need to remove the fork inner tube from the axle lug during cartridge installation.

Key Features

Application & Compatibility

The 1P.SPH.WPXACT24MX3.0 corresponds to the SPHERE 3.0 configuration developed for:

• WP 48 XACT Closed Cartridge
• Cross / Motocross use
• KTM / Husqvarna
• Selected US-market models
• Current official range: 2024-2026

This version must not be confused with:

1P.SPH.XACT-CCEN3.0 – WP 48 XACT CC Enduro

which is the dedicated Enduro configuration.

The supplied product information also specifies:

EXCLUDING 2024 KTM SX AND HUSQVARNA TC

These 2024 models should therefore not automatically be considered compatible with this SKU.

Because Dal Soggio identifies the MX cartridge specifically by market and fork configuration, compatibility should be verified from the actual WP XACT CC fork fitted to the motorcycle before ordering.

SPHERE 3.0 Bladder System

SPHERE 3.0 uses a sealed, pressurized hydraulic cartridge with an internal bladder for pressure compensation.

For the 3.0 generation, the bladder has been redesigned to be thinner and stronger.

According to Dal Soggio, the new design provides:

• increased cartridge sensitivity;
• more accurate response to fork movement;
• improved hydraulic bleeding precision;
• consistent management of internal cartridge pressure.

Independent High- and Low-Speed Compression

The redesigned compression base valve provides separate adjustment of:

• High-Speed Compression
• Low-Speed Compression

These terms refer to fork movement speed, not motorcycle speed.

Low-speed compression affects slower suspension movements such as braking load and chassis pitch.

High-speed compression becomes increasingly important during rapid fork movement caused by braking bumps, square edges, jump faces, landings, and other sharp motocross impacts.

Independent adjustment allows the suspension to be tuned more precisely for support, traction, comfort, and impact absorption.

36 mm Compression Piston

The SPHERE 3.0 compression piston measures 36 mm, replacing the previous 28 mm configuration.

Dal Soggio states that the larger piston improves the linearity of the complete front fork.

The piston operates together with the redesigned base valve and Direct Flow system as part of the complete SPHERE 3.0 hydraulic architecture.

Direct Flow Technology

SPHERE 3.0 incorporates Dal Soggio’s Direct Flow Technology.

Instead of routing suspension oil through Z-shaped passages, the piston receives oil directly.

This design is intended to:

• reduce hydraulic stress within the cartridge;
• provide a more direct oil-flow path;
• improve damping consistency;
• increase suspension-response precision.

Quick Install System

The WP XACT Closed Cartridge generation from 2024 uses Dal Soggio’s Quick Install system.

This allows installation of the SPHERE cartridge without removing the fork inner tube from the axle lug.

The system simplifies the mechanical installation procedure compared with earlier cartridge generations.

Quick Install does not remove the need for correct hydraulic bleeding, spring setup, oil-level adjustment, and final damping calibration.

Motocross Application

This SPHERE 3.0 version is developed specifically for the XACT Closed Cartridge motocross platform.

Typical MX suspension demands include:

• braking bumps;
• repeated sharp impacts;
• deep ruts;
• jump takeoffs;
• hard landings;
• rapid suspension movements.

The cartridge is designed to maintain sensitivity while providing the hydraulic support required during these higher-energy suspension events.

Recommended Oil

Dal Soggio specifies CUBE Fork Oil 5W inside SPHERE cartridges.

Correct suspension fluid is important for maintaining consistent damping response, lubrication, hydraulic bleeding quality, and repeatability.

Installation Note

SPHERE 3.0 is a professional suspension component requiring correct installation and calibration.

Installation involves:

• fitting the cartridge system;
• hydraulic bleeding;
• spring and preload setup;
• oil-level adjustment;
• compression and rebound calibration;
• final chassis-balance verification.

Because this version is market- and fork-specific, the exact WP XACT Closed Cartridge configuration should always be confirmed before installation.

Installation and setup by a qualified suspension technician or Dal Soggio specialist are recommended.
