Parmakit 57025.22 ignition for Vespa PX/PE 125-200: variable advance, 12 V 90 W, 20 cone and 1,5 kg yellow integral flywheel.

Electronic ignition PARMAKIT 57025.22 is a variable advance version for Vespa PX and PE engines with a 20 mm flywheel cone. It operates at 12 V with a declared power of 90 W and uses a 1,5 kg integral flywheel with a yellow fan. The intermediate mass of the rotor offers a compromise between promptness in increasing the revs and regularity of operation, but the performance depends on the correct setting of the phase on the engine.

Technical variant

• electronic ignition with variable advance;
• MPN PARMAKIT 57025.22;
• 12 V system, power 90 W;
• flywheel cone �20 mm;
• 1,5kg integral flywheel;
• yellow fan.

This combination of weight, color and cone distinguishes the product from the ignitions PARMAKIT PX/PE in 1,1, 1,7, 2,2, or 2,5 kg, and in gray or carbon-look versions. Before purchasing, carefully compare the shaft taper, system type, and desired mass: aesthetically similar products may have different applications and inertia.

Compatibility verified

Compatible with Vespa PX and PE 125, 150, and 200 models equipped with a 20 mm cone crankshaft and a system adaptable to the 12 V configuration. This recommendation does not automatically extend to earlier Vespa Largeframes, Smallframes, or variants with a different cone. On replaced or tuned engines, the check must be performed on the actual crankshaft and wiring, not just the declared frame model.

Installation and phasing

Before assembly, check the conical seat, key, thread, and absence of burrs. The flywheel must fit completely on the cone without oscillation. Position the stator following the instructions. PARMAKIT, then check the advance with a dial gauge and strobe light: the visual references are only a starting point. Tighten the flywheel with suitable tools and route the wiring away from rotating parts and heat sources.

Electrical system and controls

Make clean grounds and secure connections, checking the vehicle's wiring diagram and the compatibility of the regulator, lights, and any battery. After starting, check voltage, idle stability, lighting operation, and regularity at high revs. Excessive advance can cause detonation and overheating; insufficient tightening can damage the cone and key.

Real warnings

This product is intended for sports use. The 1,5 kg flywheel is not interchangeable with versions of a different mass, as it affects the engine's response. After the initial test, recheck the fastening, inspect the cables, and confirm the timing with a warm engine.
