Sealing rate for Aprilia RS 125 outlet control

Our valve densification and sealing rate is specially designed for the outlet control of the legendary Aprilia RS 125. It combines precision and durability to ensure optimal pressure structure and an even exhaust control. Each component was manufactured according to the highest quality standards in order to guarantee a fit and reduce the maintenance effort to a minimum.

The O-ring made of high-strength NBR rubber guarantees a dense seal between the housing parts and reliably prevents exhaust gases from leaving under all operating conditions, even when loaded. Its elastic properties remain even at high temperatures, which ensures a permanent sealing effect and reduces the wear of other components.

The high -quality valve wall seal protects the valve guides and minimizes the oil consumption by reliably preventing motor oil from getting into the combustion chamber. Made made of special fluorative monitoring (FKM), it remains form -stable and resistant to hot oil even under extreme loads.

The robust spring is made of feather-hard steel and takes over the precise control of the rave valve, so that it closes optimally at low and medium speed range. Due to its constant voltage, the dynamic resistance of the outlet control is evenly built up and ensures an agile response behavior.

• Suitable sealing package for easy assembly and fast installation without post -processing.
• O-ring made of temperature-resistant NBR rubber for dense sealing under extreme conditions, even at high loads.
• Valine seal made of FKM prevents oil loss at high temperatures and effectively protects valve guides.
• Spring made of feather -hard steel for constant valve control at low speeds and uniform pressure structure.
• Paper seal optimally tailored for seamless seat between the cylinder and slide housing without leaks.

Thanks to the precise paper seal between the cylinder and the slide housing, optimal air and exhaust gas flows are enabled, which significantly improves the torque and driveability.

This complete sealing and spring set is an indispensable upgrade for every Aprilia RS 125 drivers who value reliability and performance-oriented maintenance. Experience better stability of the exhaust gasification and reduce unwanted wear so that your two-stroke engine always exploits its full potential. Easy assembly and immediate operational readiness make the exchange for childish play.
