The BGM PRO ignition set made from high-quality components for a quick conversion of the Vespa to a maintenance-free, bright and reliable ignit/alternator unit.

This set is for the Vespa PK XL, PK ETS, PK HP series (also fits V50.50N, PV, ET3, etc. with the appropriate crankshaft, see also article BGM666PV20)

FEATURES

• lighter, balanced pole wheel

• good round run

• more performance

• better acceleration

• Brilliant bright light even when idle

• voltage-stabilized 12 volt electrical system

• maintenance-free and reliable electronic ignition

• Start immediately

Alternator and voltage regulator
The BGM PRO set uses a modern electrical system with voltage regulator. The alternator has modified coil wiring and produces a high voltage even at low speeds. As a result, there is a bright, stable light even when idle. At high speeds, the voltage regulator automatically adjusts to a stable and gentle 12-13 volts. This also offers the option of charging a battery and/or supporting a USB charging socket for mobile phones, GPS, etc.

Ignition
The BGM Pro ignition uses CDI technology, which has been tried and tested millions of times over, as used by Piaggio from the 1980s onward. The ignition pulse is triggered contactlessly via a so-called pick-up signal. The high ignition current, even at low speeds, ensures perfect starting behavior under all conditions. The contactless ignition release is stable well into the five-digit speed range.

Due to their weight,
the pole wheels are tailored to the respective application: At 1600 grams,
the small frame models are perfect for the lively characteristics of the small motors.
At 2300 grams, the large frame motors offer a wonderful mix of plenty of running culture and excellent acceleration capacity.
They are finely balanced, offer fantastic run, high ignition timing accuracy and very good magnetization.
Thanks to its smaller circumference and optimised wing surfaces, the engine is very well attached to the gas and has better acceleration and slightly more power.

Conversion
This set is ideal as a replacement, for example to replace a faulty ignition of a PK XL/ETS model or to have a completely new and high-quality base at hand when assembling an engine. The set is also very interesting for retrofitting previous models such as V50, PV, ET3, etc. These still have a weakly sized crankshaft with a small cone. With the introduction of the sporty ETS models and the subsequent XL models, the Vespa PK models were given a larger crankshaft. It has a larger alternator cone, recognizable by the M12 thread on the flywheel nut and the shaft sealing ring with 20x32x7mm (PK XL) or 24x35x7mm (PK ETS). The more dimensioned stump is useful for tuning with 125cc and more on the V50/PV/ET3 models (the stump can no longer break off). In order to install a crankshaft from the PK models in the older V50/PV/ET3 models, the pole wheel of the PK models is also required. This set provides the basis for raising an old motor to a modern level, both mechanically and electronically. If you also need a voltage regulator and holder for the CDI, you should take a look at the BGM666PV20 set.

CONCLUSION
Very nice set to convert the Vespa to a modern, reliable and powerful electrical system. All parts are permanently available as spare parts.
