Zenoah Pistons and Piston Rings

Quick note about Pistons and Piston Rings

After consulting with one of the top engine tuners in the UK, Freeprawn Racing would like to pass on this information about selecting the correct piston rings and pistons for your engine as all the information about all the different parts can seem confusing.  We hope this makes things simpler.

  • If you have a Zenoah 26cc engine you need the 2088 (26cc) piston ring and 2088 (26cc) Piston.
  • If you have an older Zenoah (black plug cap) you need the 2070 23cc piston ring (1mm) and 2070 23cc piston.
  • If you have a new Zenoah engine (red plug cap) or G240 you need the 2071 23cc piston ring (0.7mm) and 2071 piston.

If you have any 23cc engine and want to replace the piston and ring at the same time select the 2071 23cc piston ring (0.7mm) and 2071 piston.

Still confused or unsure, then give us a call or get in touch via the contact us page.
