External high-voltage ignition coil in classic Phenoplast or Bakelite® housing for early Vespa Largeframe and GS models with breaker ignition. Technically suitable and visually coherent as a replacement if the original coil has become unreliable after decades due to cracks, moisture or insulation damage.
The ignition coils of this generation are located on the outside of the vehicle and are exposed to vibrations, temperature changes and the weather for decades. The housing is made of phenoplast, an early fully synthetic duroplast, often referred to colloquially as Bakelite®. The material is electrically insulating and heat-resistant, but can become brittle and develop hairline cracks with age. This leads to leakage currents, misfiring or complete ignition failure.
The coil offered here is a one-to-one replacement for the original Phenoplast or Bakelite® coil on the models in question. It is fitted to the existing mounting points and electrically connected in the same way as the original. Replacement is particularly recommended for engine revisions and restorations in order to restore the ignition system to a defined and reliable condition.
Note: The basis is an original contact breaker ignition with external high-voltage coil. For converted or retrofitted ignition systems, please compare the installation situation before ordering.
