EPICA Showa49 Cartridge CRF 250/450-KXF 450-RMZ 450

Our new EPICA Cartridge System culminates years of experience, testing, and development into the ultimate spring cartridge. The goal, create a highly tunable cartridge to allow riders the ability to fine-tune their forks in ways that were never before possible.

Tuneability, we have you covered,

External adjustments:

• Compression damping – 50 clicks of adjustment
• Rebound damping – 50 clicks of adjustment
• External spring preload adjustment – 0 to 15mm– Easily adjusted with a 16mm socket at the fork bottom.
• Bladder System – Air pressure can be increased / decreased externally offering a more flexible and adjustable system for different rider preferences, terrain, and track conditions.

Innovative Features:

• Bladder System
  • Our bladder system prevents performance loss associated with standard internal pressure spring systems, which often suffer from cavitation during high speed conditions
  • Internal oil compensation with increased volume for a better high-speed response.
  • Ability to tune bladder pressures via the side bleed spring
• PDS System: Each EPICA cartridge incorporates our Progressive Damping System (PDS) for increased damping control providing increased bottoming resistance without sacrificing initial fork feel
  • The PDS system offers up to 12 different combinations of adjustments to tailor the fork feel to the individual rider needs
• High-speed compression piston is reversible, providing an unlimited range of settings.

Technical Specs:

• Machined from premium 7075 and 6060 alloys and hard anodized.
• Reversible High-Speed compression piston – outer diameter = 38 mm.
  • Side A (Flat valve surface) – 34mm OD shims for motocross and enduro.
  • Side B (Convex valve surface) – 32mm OD shims for supercross.
• Option to configure Low-Speed Valve (LSV) on compression base valve.
• Cartridge rod diameter = 14 mm (for an increased oil flow).
• Rebound piston diameter = 25mm for better hydraulic control.
• Compression high/low-speed shims ID 12 mm.
• Maximum travel = 310 mm.
• Maximum shim diameter for Mid-Valve By-pass = 21 mm.
• Ability to set Mid-Valve float clearance with the stack shims.
• Mid-Valve/By-pass floating shim ID = 6 mm (for a soft response at high speed on braking bumps).
• Rebound shims ID = 6 mm (uses Delta Shims in mid-valve to avoid oil turbulence while in compression).
• Low friction NBR bottom seal.
• Ability to extend the cartridge using nylon washers.

Model Fitment:

• CRF 450 2017-2024
• CRF 250 2018-2024
• KXF 450 2018-2024
• RMZ 450 2018-2024
