BGM Pro TOURING 2.0 Flywheel – Electronic – for conversion to fully electronic CDI ignition

The BGM PRO flywheel is a high-quality reproduction of the original Piaggio PK flywheel, which is no longer available.
We have invested in brand new cast molds, allowing us to now offer the requested conversion flywheels in fantastic quality at a very fair price.

FEATURES

• Weight Smallframe 1600 grams (V50, PV, ET3, PK - orig. up to 2800 grams)

• Weight Largeframe 2300 grams (Sprint, PX, LML, Cosa - orig. up to 3200 grams)

• High ignition timing accuracy

• Very good balance

• Factory balanced

• Good magnetization

• Increased performance due to optimized fin area

The flywheels are matched to the respective application by their weight:
The Smallframe models with 1600 grams are perfectly suited for the lively characteristics of the small engines.
The Largeframe engines offer a wonderful combination of smooth running and very good acceleration with 2300 grams.

Generally, the flywheels always require a 12V ignition baseplate/alternator. This allows any formerly contact-controlled engine to be converted to a fully electronic CDI ignition with voltage-regulated on-board electrical system. We offer complete sets with all parts required for the conversion (see Alternatives/Accessories).

Available in four versions:

• BGM8025RT: Vespa Largeframe 2300g, large cone, M12 (1978-) - PX, Cosa, LML 125/150 (2-stroke)
  For converting all Largeframe engines that already have the large cone (flywheel thread M12, wrench size 18), but still have a contact-controlled ignition installed (approx. 1978-1981, PX, Sprint Veloce, GTR, Super, TS). Here the flywheel and a new 12V ignition baseplate are needed. In later models (e.g. Vespa PX from approx. 1982, Cosa, LML) with a factory-installed electronic ignition, this can continue to be used. When converting to the BGM flywheel, you benefit from a significantly more lively engine characteristic with noticeably improved acceleration and increased engine power.

• BGM8032RT: Vespa Largeframe 2300g, small cone, M11 (1957-1977) - Sprint, GT, GTR, Super, GL, VNA, VBA, VNB, VBB, Motovespa 125/150 S/N/L
  The classic of all Largeframe engines. Still has the old type crankshaft with a thin (pointed) cone, which can be identified externally by the flywheel nut with M11 thread and wrench size 14.
  These engines always have contact ignition ex works.
  Converting the flywheel, ignition and vehicle wiring harness creates a modern vehicle electrical system that is absolutely maintenance-free and includes a strong 12V alternator that provides fantastic bright light. Starting on the first kick included.

• BGM8033RT: Vespa Smallframe 1600g, small cone, M10 - V50, 50N, Special, SR50, Sprinter, SS50, SS90, V90, 90 Racer, V100, ET3, PV, PK S
  Suitable for all Smallframe engines with a small cone (flywheel nut M10, SW14 or SW16). These engines always have contact ignition ex works (exception ET3/PK).
  Converting the flywheel, ignition and vehicle wiring harness creates a modern vehicle electrical system that is absolutely maintenance-free and includes a strong 12V alternator that provides fantastic bright light. Starting on the first kick included. PK models that already have a voltage regulator do not need a new wiring harness.

• BGM8034RT: Vespa Smallframe 1600g, large cone, M12 - PK XL/XL2, PK FL2, PK HP, PK125 ETS, Motovespa PK75 XL (96M/104M), PK75 FL (127M/128M)
  For Smallframe engines that already have the large cone (flywheel thread M12, wrench size 18).
  Replaces the original (no longer available) flywheel 1:1. When converting to the BGM flywheel, you benefit from a significantly more lively engine characteristic with noticeably improved acceleration.
  It is also often used on older engines (originally with a small cone) if they have been converted to the more stable crankshafts of the Vespa PK XL or ETS.
