THE EPIC CARTRIDGE WAS DESIGNED FOR ALL MOTORCYCLE ENTHUSIASTS WHO WANT TO HAVE THE MAXIMUM TECHNIQUE AND PERFORMANCE, ALL APPLICABLE TO THEIR SUSPENSIONS TO HAVE THE BEST IN PERFORMANCE AND, AT THE SAME TIME, COMFORT. 

We have combined all the experience, knowledge, quality of materials, years of development and testing in a single project, to provide a product that we can consider unique for the quantity of technical innovations and ideas.

External adjustments:

  • Upper register compression with 60 very sensitive clicks.
  • Lower return register with 50 very sensitive clicks.
  • External lower spring preload adjuster from 0 to 15 mm using the 16 mm socket wrench.

Innovative features:

  • Bladder system:

– Our bladder system avoids the loss of cartridge performance and decay of hydraulic support that normal spring systems can often provide.

– Internal oil compensation via increased volume bladder for better reaction at high speeds.

– Possibility of using different bladder pressures via lateral bleed spring.

  • The EPICA cartridge includes the Lainer Progressive Damping System (PDS) for greater hydraulic damping at the end of the stroke:

– Possibility of having up to 12 adjustments of the hardness level of the limit switch by repositioning the nylon ring in one of the 3 seats and by closing the passage holes at the top.

– Reversible high-speed compression piston with enormous variability in the range of settings that can be customized as desired by the tuner.

Technical specifications:

  • Quality materials for all components such as 7075-6060 aluminum alloys and anti-wear anodizing treatments.
  • Reversible high speed compression piston external diameter 38 mm:

– SIDE A (flat surface): 34 mm external diameter sipes for enduro and motocross.

– SIDE B (convex surface): 32 mm diameter blade to obtain Supercross calibrations.

  • Possibility of hydraulic control pyramid at low speeds.
  • Main rod diameter 14 mm (for greater oil displacement).
  • 25 mm return piston for greater hydraulic control.
  • Useful cartridge stroke 310 mm.
  • Maximum by-pass/midvalve blade diameter 21 mm.
  • Possibility to choose the free space in the by-pass/midvalve through the use of thick slats.
  • Floating by-pass/midvalve slats with internal hole 6 mm (for a softened response at high speeds on potholes when braking).
  • Low/high speed compression slats, 12 mm internal hole.
  • 6 mm hole reeds on the return with triangular-shaped minimums to avoid any oil turbulence in the compression phase.
  • Lower head with internal bushing lubrication/bleeding holes.
  • Low friction NBR bottom seal.
  • Teflon anti-extruder on compression piston O-ring for greater hydraulic seal.
  • Possibility of lengthening the cartridge using nylon shims.
