bgm PRO Vespa pole wheel

Vespa pole wheel bgm PRO electronics

We have developed new fan wheels. With the bgm PRO pole wheel, a very high quality reproduction of the (no longer available) original Piaggio Vespa PK fan wheel is now available.
During the development of this new pole wheel, the tried and tested and the optics have been retained, while performance and quality have been optimized. For this we have invested in, for example, brand new molds and can now offer you the pole wheels that are in demand

  • optimized and in
  • super nice finish
  • fantastic quality too
  • offer a very fair price
  • = ideal for converting to fully electronic ignition of your Vespa

bgm PRO Vespa pole wheel

FEATURES

  • Weight Smallframe: 1.600 grams (for comparison: V50, PV, ET3, PK - orig. Up to 2.800 grams)
  • Weight Largeframe: 2.300 grams (for comparison: Sprint, PX, LML, Cosa - orig. Up to 3.200 grams)
  • High accuracy of the ignition timing
  • Very good concentricity
  • Balanced at the factory
  • Good magnetization
  • Higher performance through optimized wing area

OPTIMAL WEIGHT

The weight of the bgm PRO Vespa pole wheels is tailored to the respective purpose:

  1. The fan wheels for the Vespa Smallframe-Models are with 1600 grams perfect for the lively characteristics of the small engines.
  2. The fan wheels for the Vespa Largeframe-Motors offer with 2300 grams a wonderful mixture of a lot of smoothness and very good acceleration.

Basically, the pole wheels always require a 12V ignition base plate / alternator. This means that every previously contact-controlled motor can be converted to a fully electronic CDI ignition including voltage-controlled on-board electronics. We offer to do this complete sets with all parts required for retrofitting (see alternatives / accessories) for the ignitions:

VERSIONS

Vespa Largeframe 2300g, large cone, M12 (1978-) - PX, Cosa, LML 125/150 2-stroke
(Article: BGM8025RT)

For retrofitting everyone Largeframe Motors that already have the large cone (rotor thread M12, wrench size 18), but still have a contact-controlled ignition installed (approx. 1978-1981, PX, Sprint Veloce, GTR, Super, TS) Here the pole wheel and a new 12V ignition base plate are required. In later models (e.g. Vespa PX from around 1982, Cosa, LML) with factory-installed electronic ignition, this can continue to be used. If you convert to the BGM pole wheel, you benefit from significantly more lively engine characteristics with noticeably improved acceleration and higher engine power.

 

Vespa Largeframe 2300g, small cone, M11 (1957-1977) - Sprint, GT, GTR, Super, GL, VNA, VBA, VNB, VBB, Motovespa 125/150 S / N / L
(Article: BGM8032RT)

The most classic of all LargeframeEngines. Still has the old type of crankshaft with a thin (pointed) cone which can be recognized from the outside by the pole wheel nut with M11 thread and wrench size 14.
These motors always have contact ignition from the factory.
By converting the pole wheel, ignition and vehicle wiring harness, a modern vehicle electrical system is created that is absolutely maintenance-free and includes a powerful 12V alternator that provides a fantastic bright light. Starting at the first kick included.

 

Vespa Smallframe 1600g, small cone, M10 - V50, 50N, Spezial, SR50, Sprinter, SS50, SS90, V90, 90 Racer, V100, ET3, PV, PK S
(Article: BGM8033RT)

Suitable for everyone SmallframeMotors with a small cone (flywheel nut M10, SW14 or SW16). These motors always have contact ignition ex works (exception ET3 / PK).
By converting the pole wheel, ignition and vehicle wiring harness, a modern vehicle electrical system is created that is absolutely maintenance-free and includes a powerful 12V alternator that provides a fantastic bright light. Starting at the first kick included. PK models that already have a voltage regulator do not need a new wiring harness.

 

 Vespa Smallframe 1600g, large cone, M12 - PK XL / XL2, PK FL2, PK HP, PK125 ETS, Motovespa PK75 XL (96M / 104M), PK75 FL (127M / 128M)
(Article: BGM8034RT)

For Smallframe Motors that already have the large cone (flywheel thread M12, wrench size 18).
Replaces the original (no longer available) pole wheel 1: 1. If you convert to the BGM pole wheel, you benefit from a significantly more lively engine characteristic with noticeably improved acceleration.
It is also very popular on the older engines (with originally a small cone) if they have been converted to the more stable crankshafts of the Vespa PK XL or ETS.

New Lambretta pole wheel bgm PRO

lambretta-ignition-bgm

The bgm PRO Lambretta pole wheel is completely Made in Germany.
The fan wheel is a one-piece design, completely without screws or rivets. The pole wheel was specially designed to bgm PRO Lambretta ignition components designed, but also works with all other electronic ignitions based on the Ducati design.

The new Lambretta flywheel and all other high-end ignition components are now available here:

Pole wheel -BGM PRO electronics- Lambretta GP, DL
Pole wheel -BGM PRO electronics- Lambretta LI, SX, TV

data

  • Moment of inertia 6240 kg / mm² (-5%)
  • Weight dl / GP 2025 grams
  • Weight LI / SX 2051 grams
  • Imbalance <100 gmm
  • Burst test 24.000 rpm
  • Improved cooling effect

Totally new design

The fan wheel is a completely new design that has been made around the existing bgm ignition components. The goals were maximum reliability and a strong alternator performance.

Highest reliability

In order to be able to guarantee the greatest possible reliability, the cone is neither screwed nor riveted, but is cast in place. Each cone is checked and reworked after casting to ensure an optimal fit to the crankshaft.
We do specify the weight of the fan wheel, but this is of secondary importance in relation to the engine running. Here the achieved moment of inertia is the decisive value. In other words, how and where the weight is distributed on the circumference.

This Lambretta pole wheel is a stunner

The balance factor is the next interesting factor. Here we achieve a value that is also used in real motorsport. Each fan wheel is individually brought to at least this value. This is the best value ever achieved for a Lambretta fan wheel.
The fan wheel passed the burst test up to 24.000 rpm without any damage.

Compatible

Of course, the bgm PRO pole wheel can also be used with all components based on the original Ducati design with 6 coils. Such as Indian, AF, AFR, Vespa components. However, problems can arise here due to the many different tolerances, which are usually based on the orientation of the pickup to the trigger.
