- For better starting properties of the Motobi and on customers' request this new version has a modified rotor (now: 1.8kg / 125mm diameter / 180W - previously: 0.7kg / 103mm diameter / 100W). (This new rotor may not be used with the older 103mm systems!)

- To the older version (system 70 69 999 00) with the lighter and smaller rotor (for reference only, no more on offer)

- Magnet based generator with integrated fully electronic ignition. Output at 12V/180W DC. Solid state ignition with own power supply from within the system. Completely replaces old magneto system.

- You may drive without battery, if you want. Ignition advance is effected fully electronically and follows the characteristics of the original centrifugal governor. You have a choice of different advance characteristics.
