2010 – 2010 is the green year of ecology for Seven. we designed and produced 5 prototypes of 20Hp electrical engines with 6 speed gearbox. This product was made for a company involved in the world of clean energy. At the end of the acceptance tests, production and sales will continue starting from 2011.
2012 – The innovative ideas expanded into other sectors using our experience and know how in fluid dynamics and, in collaboration with the architect Ennio Pasini, experimentation began in the construction of a small wind farm capable of developing up to 1 kW of energy in any place.
2013 – Year of the “Fast Rent”. The first rental kart dedicated to drivers who would like to experience the world of racing with 2 stroke hi revving engines with 2 gears was completely built in house and delivered to track, Seven rental era starts here..
