Ready to win

The SIGMA RS has been developped especially for medium tyres in Rotax and KF, where the longer wheelbase and welded column support will ensure more effectiveness.


A lot of work has been done on the brake system to provide more sensibility and progressivness. The design and manufacture of the SIGMA RS allow drivers to improve performance over the duration of the race.
