Piston -MALOSSI- Minarelli vertical AC, horizontal AC / LC, Ø 40,0 - Piston pin Ø 10 - 2 piston rings

TIP: Always install piston rings carefully. Piston rings made of cast material are only elastic to a limited extent and break relatively quickly.
Some pistons have trapezoidally profiled piston rings (so-called keystoner rings), these only fit in one installation position. If the ring does not move freely, please loosen it carefully and reinstall it turned 'upside down'.
