Vespa Largeframe Conversion to electronic ignition
Vespa engines of the LargeframeModels with rotary valve inlet control, e.g. Vespa VNA, VNB, VBA, VBB, VLA, GT, GTR, Sprint, Rally, PX, LML 2T, Bajaj Chetak can now be easily converted:
Why should I convert a Vespa to electronic ignition?
These are the advantages of an electronic ignition!
After the retrofit, the former weak 6Volt on-board network is available powerful 12 volt light output. The previously self-regulating electrical system is switched to a reliable and bulb-friendly controller control (e.g. with BGM6690) changed. The high-quality cabling ensures that the high light and ignition power With its high wattage, it already provides one when idling very good light outputwhich does not break down even when using the indicators or additional power consumers. No maintenance required! Maintenance work, as is usual with contact ignitions, is not necessary.
Our new bgm ignition: specially developed for converting contact-controlled motors to a maintenance-free electronic ignition:
The latest version of the proven bgm PRO HP (High Power) ignition base plate for converting from contact ignition to electronic ignition.
Suitable for e.g. Vespa Largeframe such as: VNA, VNB, VBA, VBB, GL, Super, Sprint, GT, GTR, TS, Rally

bgm PRO ignition base plate
We have our own brand bgm, tried and tested a thousand times bgm PRO ignition base plate revised and even better did. Particular attention was paid to the very high quality of the bobbins and the pickup.
In addition, the cabling was converted to textile-sheathed silicone lines. A special gimmick is the cord already attached to the cable branch for easy pulling of the cable harness through the cable duct in the motor housing. The base plate now also has a degree of precise scaling for easier setting.
Compared to a conventional electronic ignition, the BGM Pro HP V2.5 ignition base plate has specially combined coil windings.
This significantly improves the efficiency of the alternator and offers a high light output of 120W.
In contrast to a Vespa PX ignition base plate, the BGM Pro HP has one longer and differently laid cable branch so that the ignition base plate can also be perfectly mounted on older vehicles. In addition, it has an adapted base plate contour so that it fits perfectly on engines before 1977 (with a larger shaft seal seat than PX).
- High light output (120W) thanks to the maximum number of windings
- Proven excitation coil with copper plate for maximum reliability
- Pickup with a carbon barrier layer for a clean ignition pulse
- Neatly processed light coils
- High quality solder joints
- Original cable lugs and length for easy cabling
- Can be combined with additional modules (PiFi, Kytronic, Agusto)
NOTE: The BGM Pickup has a nominal resistance of 100 Ohm (+/- 10Ohm)
ADVANTAGES OF SILICONE LINES
- Extremely temperature resistant (-40 ° C to + 250 ° C)
- Always stay flexible
- Very good mechanical protection through the textile fabric
- Resistant to fats, oils, alcohols, oxygen, ozone
- Very high insulating properties
CONVERSION TO ELECTRONIC IGNITION
When converting from a contact ignition to this base plate, another fan wheel, a voltage regulator and a CDI must be used.
A possibly standard old voltage regulator, like the series ignition coil, is no longer required.
With the BGM voltage regulator BGM6690, a battery (12 volt battery required) can optionally be charged while driving. The old wiring harness can still be used, but the previously individual circuits must be combined here, as the voltage regulator only offers one outlet to the complete power supply. It is easier to convert to one of our conversion wiring harnesses (e.g. 9077011).
Everything necessary for this is available individually or as a set.
Suitable for Vespa oldieLargeframe
The BGM ignition stator fits all Vespa engines of the Largeframemodels with rotary valve inlet control, e.g. Vespa VNA, VNB, VBA, VBB, VLA, GT, GTR, Sprint, Rally, PX, LML 2T, Bajaj Chetak.

Conversion set
In addition to the ignition, you also need a few other parts to convert the engine from contact ignition to electronic ignition. We have put together a practical set for you: BGM6661PRO
All parts are also available individually:
PLEASE NOTE
The alignment of the crankshaft in the engine housing, and thus also the position of the pole wheel, is the same as the old one Largeframe Engines (recognizable by the same-sized crankshaft bearings with 25x62x12mm) are significantly more variable than, for example, the later PX engines.
The crankshaft bearings are not fixed in the engine housing by a circlip, but simply sit with a slight interference fit in the housing. Various tolerances (e.g. the width of the shaft sealing rings, worn bearing seats, orientation of the cone on the crankshaft) can lead to significant deviations from the originally intended positioning of the shaft in the crankcase. A prerequisite for a correctly working ignition is that the pole wheel is perfectly aligned with the ignition base plate. Otherwise the trigger surface in the pole wheel will not run parallel to the pick-up, which can lead to misfiring. If the ignition does not produce a spark, the fault is usually to be found here. For easy rectification, we offer spacer plates (BGM8000S05) for the pickup on the ignition base plate. This allows the correct distance to be restored in a simple manner.
The bgm PRO conversion ignition fits the following models:
