Piston ring -PARMAKIT 135cc W-Force, SP09, SP09 Evo, SP09 Evo C- Vespa PV125, ET3 125, PK125 - Ø=58mm

TIP: Please always mount the piston rings carefully. Piston rings made of cast material have only limited elasticity and break relatively quickly.
Some pistons have trapezoidally profiled piston rings (so-called keystone rings), these only fit in one installation position. If the ring does not move freely, please loosen it carefully and reinstall it upside down.
