AIRSAL Ring Set Ø58 mm (Manufacturer Ref: 11046458) — piston rings designed for 150 cm³ displacements. Engineered for direct replacement, these rings fit a bore of 58 mm and are placed around the piston to restore sealing and engine performance after disassembly or engine refurbishment.

• Compatibility: suitable for 150 cm³ engines equipped with a Ø58 mm piston, including the Honda PS 150 Passion I (KF09) models from 2010–2012.
• Function: the rings limit compression loss and reduce oil leaks into the combustion chamber, contributing to better engine response and controlled fuel consumption.
• Practical advantage: direct replacement for a quick restoration of the top-end during a cylinder/piston kit or in-depth maintenance.
• Wear and friction: designed to minimize friction between the piston and cylinder and slow down wear, without promising unverifiable gains in power.

This product is aimed at riders looking to maintain their urban engine and restore proper sealing after disassembly. For optimal installation, always check the condition of the cylinder, the ring gap, and adhere to manufacturer recommendations during reassembly.
