CUSTOM ADJUSTABILITY

Along with pre-load and rebound tuning, the ER30 is equipped with CTS (Compression Tuning System), a patented Formula / TECH Suspension innovation.

This system allows quick, tool-free adjustment of low- to mid-speed compression damping for varying terrain or riding style.

Spring rate options:

• 78.8 N/mm (standard) — recommended for average-weight riders

• 105.6 N/mm (optional) — ideal for heavier riders, high-impact riding, or aggressive terrain

PERFORMANCE FEATURES

• Piggyback Reservoir: Increased oil volume for improved thermal stability during extended or aggressive riding.

• Internal Floating Piston (IFP) with Double Seals: Prevents gas/oil mixing, ensuring consistent damping and long-term performance.

• High-Profile MDU Bumper: Increases end-stroke support and improves bottom-out resistance.

• DU Bushings: Low-friction, durable mounting that maintains precision under high load and harsh terrain.
