The Talaria rear shock (FastAce absorber) is the OEM-grade replacement rear shock for the Talaria Sting series — fitted to Sting 4000 (TL4000), Sting Offroad (TL3000), Sting Onroad (TL45), and Sting R Road Legal (TL50). Oil-damped construction with the factory mount geometry. Direct bolt-on replacement after the original shock blows seals or the damper oil degrades.
Talaria Rear Shock: Fitment & Compatibility
Confirmed factory fitment across the four Sting trims that shipped with the FastAce rear shock. Newer chassis (MX5 Pro, Komodo, Dragon) use different mono-shock geometries. Fitment runs across the main Talaria Sting platform, with model-specific notes below.

Rear-shock failure on a Talaria usually shows up as oil weeping at the seal, a soft “bouncy” feel, or visible damage after a hard landing. Replace immediately — a failed rear shock destroys handling and accelerates frame wear at the mounting points. See the rest of our Talaria parts catalogue for matching components.
Install Notes
Difficulty: Moderate. Tools: torque wrench, hex key set. Time: 30-45 minutes. Support the bike on a stand with weight off the rear wheel before removing the shock. Re-torque mounting bolts to Talaria service-manual spec after fitting and again after the first ride.
Frequently Asked
Will this FastAce shock fit my Sting MX5 Pro?
No — the MX5 Pro uses a different adjustable linkage shock geometry. This FastAce shock is for the earlier Sting 4000, Offroad, Onroad, and Road Legal trims only.
Is the shock adjustable?
The FastAce OEM-grade shock has factory damping settings. For adjustable preload, compression, and rebound damping, look at higher-tier aftermarket shocks (EBMX, Manitou, FastAce premium tier).
Trust Signals & Warranty
FastAce backs the shock against manufacturing defects per their standard suspension warranty. Talaria USA covers a 30-day return window on unmodified parts and ships from our US warehouse in 2-4 business days.
