FSR-48 Complete Racing Front Fork for WP Xact EN – Sphere 3.0

The Dal Soggio 1P.FSR-48XACTEN3.0 FSR-48 Complete Front Fork is a high-performance suspension system developed for WP Xact Enduro 2021–2023 applications.

Rather than being a simple internal upgrade, the FSR-48 is a complete fork assembly designed around premium materials, precision machining, low-friction surface treatments, and Dal Soggio’s Sphere 3.0 suspension technology. Dal Soggio officially identifies this version as the WP Xact EN 21–23 3.0 configuration.

The outer fork tubes are manufactured from ERGAL 7075 T6 aluminum alloy and receive extensive internal machining intended to improve smoothness and reduce friction within the fork structure.

The inner tubes feature a DLC coating on the external sliding surface together with hard anodizing on the internal surface, combining low-friction operation with increased surface durability.

At the heart of the fork is the Dal Soggio Sphere Kit 3.0, providing the hydraulic damping system around which this complete fork configuration is built. Dal Soggio also lists this WP Xact 2021–2023 Enduro configuration within its current Sphere 3.0 / FSR-48 product ecosystem.

The fork is equipped with SKF seals, while the axle lugs are manufactured from ERGAL 7075 T6 and CNC machined from solid material for precise geometry and structural consistency.

Key Features

• Complete FSR-48 racing front fork developed specifically for WP Xact Enduro 2021–2023 applications
• Sphere 3.0 hydraulic suspension system provides the core damping architecture
• ERGAL 7075 T6 outer tubes feature extensive internal machining for smooth fork operation
• Inner tubes combine external DLC coating with internal hard anodizing for reduced friction and increased durability
• CNC-machined ERGAL 7075 T6 axle lugs and SKF seals complete the high-specification construction

Application & Compatibility

• WP Xact Enduro – 2021–2023

The official Dal Soggio product page identifies this SKU specifically as the WP Xact EN 21–23 version.

Exact motorcycle model compatibility should still be verified before ordering, as the official product page defines the fork by WP platform and model-year range rather than listing every compatible motorcycle.

Suspension Technology

Sphere 3.0

The FSR-48 uses Dal Soggio’s Sphere 3.0 hydraulic suspension system, integrating the cartridge technology directly into a complete fork assembly rather than requiring the customer to retain the original production fork structure.

ERGAL 7075 T6 Construction

Dal Soggio uses ERGAL 7075 T6 for both the outer tubes and axle lugs. The outer tubes are extensively machined internally, while the lower fork feet are machined completely from solid material.

DLC & Hard-Anodized Inner Tubes

The inner tubes use:

• DLC coating externally
• Hard anodizing internally

These treatments are intended to improve sliding behavior, wear resistance, and consistency of suspension operation.

Installation & Setup Note

The 1P.FSR-48XACTEN3.0 is a complete front fork assembly developed for the WP Xact Enduro 2021–2023 platform.

Before installation, verify:

• motorcycle application,
• axle and brake interface,
• fork clamp compatibility,
• spring and damping setup,
• chassis balance and fork height.

Professional suspension installation and setup are recommended to ensure correct fitment and obtain the intended performance.

This SKU is the WP Xact Enduro 2021–2023 version. It should not be confused with the later WP Xact CC 2024–2026 FSR-48 configuration, which Dal Soggio lists under a different part number.
