Flywheel BGM ORIGINAL TOURING 2.0 Electronic 2300g Vespa Largeframe Sprint150 (VLB1T), GT1

The BGM PRO flywheel is a very high-quality reproduction of the no longer available original Piaggio PK flywheel.
We have invested in brand-new molds and can now offer the sought-after conversion flywheels in fantastic quality at a very fair price.

FEATURES

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

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

• High ignition timing accuracy

• Very good concentricity

• Balanced ex works

• Good magnetization

• Higher performance due to optimized wing surface

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

In principle, the flywheels always require a 12V ignition base plate/alternator. This allows any formerly contact-controlled engine to be converted to fully electronic CDI ignition, including voltage-controlled onboard electrics. We offer complete sets with all parts needed 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, width across flats 18), but still have contact-controlled ignition installed (approx. 1978–1981, PX, Sprint Veloce, GTR, Super, TS). You need the flywheel and a new 12V ignition base plate. For later models (e.g. Vespa PX from approx. 1982, Cosa, LML) with factory-installed electronic ignition, it can continue to be used. Converting to the BGM flywheel provides a noticeably livelier engine characteristic, significantly improved acceleration and higher engine performance.

• 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 most classic of all Largeframe engines. It still has the old-type crankshaft with a thin (pointed) cone, identifiable externally by the flywheel nut with M11 thread and 14 mm wrench size.
  These engines always have contact ignition ex works.
  By converting the flywheel, ignition and vehicle wiring harness, a modern vehicle electrical system is created that is completely maintenance-free and includes a powerful 12V alternator providing fantastically 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).
  By converting the flywheel, ignition and vehicle wiring harness, a modern vehicle electrical system is created that is completely maintenance-free and includes a powerful 12V alternator providing fantastically bright light. Starting on the first kick included. PK models that already have a voltage regulator do not require 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, width across flats 18).
  Replaces the original (no longer available) flywheel 1:1. Converting to the BGM flywheel provides a much livelier engine characteristic with noticeably improved acceleration.
  It is also very popular on older engines (originally with a small cone) when they have been converted to the more stable crankshafts of the Vespa PK XL or ETS.
