This scooter is the second prototype produced using an SR subframe and Piagio engine. It has been used as a rolling prototype for the development of the "Series 4" fully fabricated frame and adjustable front suspension.

The front suspension is designed for extra travel and has 3 positions of spring tension, to allow the rider to select settings to suit load and riding / road conditions. Used in conjunction with the adjustable rear shock a smooth ride can be obtained on most road surfaces.

The engine has been fitted with the Mallosi 172cc cylinder, 25mm Dellorto carb, converted P.M. pipe and UPGEAR kit giving performance "well exceeding" a standard Gilera 180. For more information see Scootering magazine test report.

The Series 4 has now been superseded by the Series 5
