The Basso story starts with the welding of a steel frame!
Not content to take the current technology of the time as the Basso standard, Alcide Basso set forth to study, investigate and innovate new methods of construction, material preparation and frame building.
That tradition has been maintained throughout Basso’s history and the Viper model represents all that was learned during that long journey that looked to perfect steel frame construction.
The experience in welding of our technicians are our best tool in obtaining lighter weights and major resistance to torsion and flexion.
The frame and fork are welded with lugs, tubes are internally tapered for extreme performances and aesthetical beauty.
Made by hand, made in Italy, made by Basso the Viper blends traditional looks and style with the capability to build modern componentry, thus creating an elegant, sophisticated bike that begs for speed yet offers a ride quality without comparison.
