BGM PRO ProRev Ignition Base Plate – Vespa PK XL with Battery
Greater light output, more precise ignition signals, and a robust design: The BGM PRO ProRev is the logical evolution of our proven electronic ignition base plates for classic Vespa engines.
This version was developed for the Vespa PK XL with battery, 5 coils, and a 5-pin round connector. It replaces the corresponding original ignition base plate and handles both the power supply for the electronic CDI ignition and the power generation for the lighting and on-board electrical system.
The advantages of the ProRev at a glance
- Optimized HP light coils: High light output and efficient power supply
- Reinforced BGM pickup: Robust construction with precise signal transmission to the CDI
- Redesigned coil windings: Designed for reliable operation even at high RPMs
- Improved wiring: Sturdy conductors with an optimized ratio of cable cross-section to insulation thickness
- Precise degree-accurate adjustment marks: Facilitate positioning and ignition timing adjustment
- Authentic connection design: Easy replacement without modifying the wiring harness on compatible vehicles
Optimized light coils for lighting and the vehicle’s electrical system
The five-coil BGM PRO ProRev uses optimized HP light coils with windings designed for low electrical losses and efficient power generation.
This benefits both the lighting system and the vehicle’s electrical system. A reliable electrical supply is particularly important in vehicles with a battery, as the vehicle’s electrical loads must be taken into account in addition to the ignition system.
The ProRev is designed as a high-quality replacement for the corresponding original ignition base plate. Provided the vehicle’s electrical system is intact and correctly configured, no additional modifications to the lighting system are required for the replacement.
Reinforced pickup – precise ignition pulses
The pickup sensor provides the CDI with the signal for the ignition timing. Reliable signal transmission is therefore crucial for smooth engine operation and stable ignition performance.
The BGM PRO ProRev features a redesigned, mechanically reinforced pickup with a carbon barrier layer. Its design is engineered for precise and consistently reliable signal transmission.
The excitation coil and high-quality soldered connections also contribute to operational reliability. The redesigned wiring with robust conductors also makes it easier to route the cables through the engine housing opening.

Important: Distinguish between versions with and without a battery
The ignition base plates for the Vespa PK series differ, among other things, in their electrical configuration and the pinout of the round connector.
- With battery: 5 coils, 8 wires, round connector with 5 terminals—this version
- Without battery: 5 coils, 6 wires, round connector with 3 terminals – different version required
The actual wiring configuration of the vehicle is decisive. Before ordering, compare the number and pinout of the contacts on the round connector with those of the existing ignition base plate. Especially in older vehicles, modifications may have been made to the electrical system.
Installation and Ignition Adjustment
If the connector types match, the BGM PRO ProRev can be installed in place of the original ignition base plate.
The precise angle markings facilitate the initial adjustment. To ensure correct ignition timing, the specified ignition timing must be verified with an ignition timing gun after installation.
During installation, the cable routing, plug connections, ground contacts, and the condition of the voltage regulator should also be checked. Faulty vehicle electrical systems cannot be resolved by replacing the ignition base plate alone.
Scope of Delivery
- 1 × BGM PRO ProRev ignition base plate, complete with coils, pickup, and connection cables
- 5-pin round connector for the corresponding battery type
CDI, voltage regulator, pole wheel, and battery are not included.
Frequently Asked Questions (FAQ)
Does the ignition base plate also fit a Vespa PK XL without a battery?
No. For the standard model without a battery, a different base plate with six cables and a 3-pin round connector is required. Check your existing electrical system before ordering.
Does the ProRev also improve lighting performance?
The optimized HP light coils are designed for efficient power generation and high light output. The actual available output also depends on the pole piece, voltage regulator, wiring, and electrical loads.
Does the ignition need to be adjusted after installation?
Yes. The existing adjustment marks facilitate installation but do not replace the need to check the ignition timing with an ignition timing gun.
How can the pickup be tested?
The BGM PRO ProRev pickup has a nominal resistance of 100 ± 5 ohms. The measurement is performed using a suitable multimeter at the corresponding terminals. Be sure to follow the manufacturer’s specifications and account for any potential influences from other electrical components.
Can the original CDI be reused?
In a vehicle equipped with a compatible electronic PK ignition system, the ProRev is designed to replace the original ignition base plate. The existing CDI can generally continue to be used, provided it is in good working order and compatible with the ignition system.
