The fully electronic BGM Pro conversion ignition provides a strong spark, bright light and reliable starting in all weather conditions. The kit is a complete replacement for the old (contact controlled) ignition system including self-regulating 6 volt alternator.

• 12Volt high power output

• reliable contactless CDI ignition

• forever maintenance free

• high light output

• better acceleration

• higher performance

• battery charging possible

• BGM Pro voltage regulator included

• for crankshafts with small cone (Lima shaft seal Ø19mm)

IGNITION SYSTEMAND POLE WHEEL
The set includes a powerful, forever maintenance-free electronic ignition system along with powerful 12Volt alternator including modern BGM Pro voltage regulator. The BGM PRO pole wheel type Vespa PK125, is adapted for use in the smallframe engines with small crankshaft stub.

CDI (IGNITION COIL)
The thyristor controlled high power CDI (high voltage capacitor ignition) produces a very stable and powerful ignition spark with up to 40000 volts.
This always guarantees easy and reliable starting, even in the most adverse weather conditions and/or low starting speed.
The contactless ignition guarantees perfect combustion of the mixture even at the highest speeds, the notorious contact flutter is history with this set.

PERFORMANCE
The weight-optimized pole wheel noticeably improves performance as well as acceleration without compromising the durability of the engine.

RELIABILITY
The BGM Pro conversion kit is based on technology developed by Piaggio. This is extremely robust and still the first choice for all touring riders, globetrotters and mile eaters. BGM has further refined this technology and now makes it available for older vehicles with this set. Once installed, you never have to worry about it again.

LIGHT
With the light coils connected in series, the alternator generates high voltage even at low RPMs, ensuring good illumination and visibility. As the RPM increases, the voltage is limited to a maximum of 14.2 volts by the included BGM Pro voltage regulator. So you have, compared to the original old alternator, already from idle speed an excellent light output without fear of having to burn out the bulbs at high speeds.

BATTERY
The BGM Pro voltage regulator also offers a regulated DC (max. 14.3V DC) output. At this a battery can be charged and/or the current for e.g. a USB charging socket can be tapped (cell phone, Navi etc.).
Notes: The DC current can only be measured correctly with a connected load. The DC output is always prioritized: If a lot of load is demanded at the DC output, it is no longer available to the AC output.

WIRINGHUMB
Technically, it is (theoretically) possible to continue using the old wiring harness (with modifications) in many cases. However, this requires some electrotechnical knowledge, since the original wiring harness is often designed as a so-called short-circuit electrical system and its switches are thus designed as normally closed contacts. In addition, the new alternator has only one current carrying cable which leads to the voltage regulator. From there, the entire electrical system is supplied. The old original alternator, on the other hand, has individual coils for different supply areas.

We therefore recommend replacing the original wiring harness, which is usually desolate and oxidized due to its age, with our new and perfectly fitting conversion wiring harness. This already comes with a matching light switch (see also `Accessories`) and facilitates the conversion to modern onboard electronics enormously.

FIT
Suitable for all Vespa Smallframe models that still have the small crankshaft cone (recognizable by the diameter of the crankshaft stub with Ø19mm on the running surface of the oil seal. As a rule, the pole wheel nut has a M10 thread). Fits V50, 50N, SS50, SS90, V90, 90 Racer, V100, PV125, ET3, PK50 S, PK80 S, PK100 S, PK110 S.

Not plug and play suitable for V50 of the first series (V5A1T/V5SA1T with small engine flap, years of construction to ca.1965). Here a spacer for the fan cover is needed (see accessories).

CONCLUSION: With the BGM Pro conversion ignition, the scooter becomes altogether more agile, reliable and safe. A sensible and value-enhancing
