BGM Pro Electronic Lightened Flywheel - Lambretta GP


BGM PRO flywheel completeley developed and manufactured in Germany. This is a one piece item without any rivets or screws. It features 21st century technology with nearly original looks. It is successfully tested up to 24.000 rpm, offers the highest power when used with the V3 bgm stator plate.


Feature list:

  • Weight dl/GP 2025 gramm
  • Weight LI/SX 2051 gramm
  • Imbalance test less100 gmm
  • Burst test 24.000 rpm
  • Better cooling

    The flywheel is a complete new design based on our experience with all sorts of Lambretta ignitions and the knowledge of our manufacturer. Instead of the weight we refer to the torque of inertia figure. This has an impact of the engine running, smoothness of engine as well as longevity of the crank drive.
  • Balancing is the next key issue. It is done to a figure that is used on race engines as well. Each flywheel is individually matched to this figure in Germany. This is the most accurate balancing on a Lambretta flywheel ever.

    The flywheel is designed for ultimate reliability and power. It is a one piece casted item. Each flywheel boss is re-machined after the casting procedure to assure a 100 % fitment to the Lambretta crankshaft taper. The flywheel is successfully tested to 24.000 rpm. The bgm PRO flywheel is offered as an upgrade for all electronic ignition kits. 

    Balancing, machining and quality are second to none.
