Unsure if it’s the right part?
The Air Bleed Valve is a genuine spare part manufactured by Piaggio so you have peace of mind the Air Bleed Valve part being sold by Motorcycle Spare Parts is both original and new.
Specified for RX-SX 125 models built between 2008 and 2010, 890310 is the OEM air bleed valve used to purge trapped air from the relevant hydraulic or cooling circuit. It restores consistent system pressure following service work.
Sealing depends on both thread integrity and seat condition, so damaged mating surfaces can cause leaks even when tightened. Installation should be done carefully to avoid distorting the seat or damaging alloy housings.
