OMEGA Rear Shocks

A ’90s legend in the MBK and Peugeot racing scene, OMEGA is making a triumphant comeback! These super deluxe, oil-pneumatic rear shocks are engineered for peak performance. Ditching the springs, they use a cutting-edge piston system powered by oil and nitrogen, delivering unmatched damping and rebound control for the ultimate ride.


OMEGA Shocks Adjustment

Before releasing the nitrogen from the OMEGA rear shocks to soften them, use a tire preassure gauge to take an initial reading, which should be between 31 psi and 29 psi. Release the nitrogen in quick bursts to bring the pressure down to 25 psi. If needed, try lowering it further to 20 psi and see if that provides the desired softness.


OMEGA Atmospheric Air

Avoid introducing atmospheric air into your OMEGA shocks, as it can introduce moisture that may lead to seal degradation, oil contamination, and a significant decline in performance.


OMEGA Nitrogen Refill

A welding supply store is a reliable source for refilling nitrogen in your OMEGA shocks.


OMEGA Preassure

OMEGA rear shocks are pre-filled with nitrogen at a pressure of 2 bars (approximately 29 PSI).
