E-Moto ER30 Rear Shock Tech Suspension by Formula | For Talaria Sting MX3/MX4/MX5 and Altis Sigma

Race-Ready Rear Suspension Built Specifically for Lightweight E-Motos

If you are pushing your Talaria harder than stock suspension can handle, this is the upgrade that changes everything. The E-Moto ER30 Rear Shock by Formula / TECH Suspension is purpose-built for lightweight electric dirt bikes, delivering a precise balance of rear-end support and trail sensitivity.

Designed and engineered specifically for modern e-moto platforms, the ER30 gives you better traction, improved bottom-out control, and consistent damping under aggressive riding. Whether you are riding tight singletrack, hitting jumps, or charging through rough terrain, this shock keeps the rear planted and predictable.

Engineered for Talaria and Beyond

Shock Size: 288 × 85 mm (283mm eye-to-eye with 85mm stroke)

Talaria-Specific Fitment:
288 × 85 mm fits all Talaria Sting models using the linkage mount system.
Also compatible with Altis Sigma / Sigma MX (direct mount).

Custom Adjustability with CTS Technology

Beyond standard preload and rebound adjustment, the ER30 features CTS (Compression Tuning System), a patented Formula and TECH Suspension innovation. This user-friendly system allows fast, on-the-fly tuning of low- to mid-speed compression damping without complicated tear-downs.

The result is real-world adjustability that lets you dial in traction, cornering stability, and impact absorption based on rider weight, terrain, and riding style.

• Rebound: 24 clicks

• Compression (CTS): 20 clicks

• Spring Preload: 0–20mm adjustment

• Factory Settings:

  • Spring preload: 8mm

  • Rebound: 12 clicks out

  • Compression: 10 clicks out

Spring Rate Options

• 78.8 N/mm (Standard) – Ideal for average-weight riders

• 105.6 N/mm (Optional) – Recommended for heavier riders or aggressive terrain

• 450 lb/in Lightweight Spring – Matte graphite finish (upgradeable to 600 lb/in)

Performance Features

• Piggyback Reservoir: Increases oil volume for enhanced thermal stability under sustained high load

• External Gas-Charged Reservoir: 10 bar (150 psi) nitrogen pressure for consistent damping

• Internal Floating Piston (IFP) with Double Seals: Prevents oil and gas mixing for long-term reliability

• High-Profile MDU Bumper: Derived from TECH trials suspension for improved bottom-out resistance and progressive end-stroke feel

• DU Bushings: 24mm total mount width for secure, low-friction, durable mounting

CTS Valve System

• Includes medium “Orange” CTS valve

• Interchangeable compression valves available for fine-tuned setup

Kit Includes

• Tech Suspension 283mm Rear Shock

• Dedicated Talaria TECH Linkage (required for proper fitment)

• Shortened Linkage Rod for 16” rear wheel setups

Important: This shock must be used with the included TECH linkage. You cannot run alternative linkages such as Warp 9, Prickly, or others with this setup.

For riders running a 16” rear wheel, the included shortened linkage rod ensures proper geometry and clearance.

What Makes the ER30 Stand Out

The combination of CTS compression tuning, piggyback thermal stability, and TECH-derived MDU bottom-out control makes this one of the most refined rear shock upgrades available for Talaria platforms. It is built to handle the instant torque and added weight bias of electric dirt bikes while maintaining small-bump compliance and traction.

If you are tired of blowing through travel, overheating stock shocks, or feeling rear-end instability under power, this is a serious step up in control and confidence.
