The BGM PRO Pole Wheel is a very high quality reproduction of the no longer available original Piaggio PK Pole Wheel.
We have invested in brand new molds and can now offer the sought after conversion pole wheels in a fantastic quality at a very fair price.
FEATURES
Weight Smallframe 1600 grams (V50, PV, ET3, PK - orig. up to 2800grams)
Weight Largeframe 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 pole wheels is matched to the respective application:
At 1600 grams, the smallframe models are perfectly suited to the zippy characteristics of the small motors.
The Largeframemotors offer with 2300 grams a wonderful mixture of a lot of running culture and very good acceleration.
Basically the pole wheels always need a 12V ignition base plate/alternator. This allows any formerly contact-controlled engine to be converted to a fully electronic CDI ignition including voltage-controlled on-board 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 the conversion of all Largeframe engines which already have the large cone (pole wheel thread M12, width across flats 18), but still have a contact-controlled ignition installed (approx. 1978-1981, PX, Sprint Veloce, GTR, Super, TS). Here you need the pole wheel and a new 12V ignition base plate. For later models (e.g. Vespa PX from ca.1982, Cosa, LML) with factory installed electronic ignition, this can be used further. Here one profits with a conversion to the BGM pole wheel from a clearly spritziger engine characteristic with noticeably improved acceleration as well as a 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 large frame engines. Still has the old type crankshaft with thin (pointed) cone which is recognizable from the outside by the pole wheel nut with M11 thread and wrench size 14.
These engines always have a contact ignition ex works.
Here, 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 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 small cone (pole nut M10, SW14 or SW16). These engines always have a contact ignition ex works (exception ET3/PK).
Here, 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 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 (pole wheel thread M12, width across flats 18).
Replaces the original (no longer available) pole wheel 1:1. Here you benefit from a conversion to the BGM pole wheel of a much livelier engine characteristics with noticeably improved acceleration.
It is also very popular on the older engines (with originally small cone) used when these were converted to the more stable crankshafts of the Vespa PK XL or ETS.
