EPICA Cartridge Spring Conversion WP XACT 48mm KTM / GASGAS / Husqvarna 2021–2025

The EPICA Cartridge Spring Conversion for WP XACT 48mm forks improves front-end feel, damping consistency, and rider confidence. The system converts the OEM air fork into a premium closed-cartridge spring configuration.

As a result, riders experience improved traction, better chassis stability, and a more connected feel across rough terrain.

Unlike traditional air fork systems, the EPICA spring conversion delivers a more planted and predictable ride feel throughout the entire moto. In addition, the spring-based design helps reduce the pressure changes commonly associated with air forks.

The EPICA Cartridge system is engineered to improve oil flow control while reducing harshness and unwanted fork deflection. Consequently, riders benefit from improved braking stability, better cornering feel, and increased comfort in rough conditions.

Designed and manufactured in Italy, the EPICA system combines premium internal components with race-proven damping technology for motocross, off-road, and competitive race applications.
