MV AGUSTA produced the 175 'CSS-5V Regolarità Monoalbero' between 1954 and 1956.
Initially fitted with the 175 'CSS' engine, they replaced it in 1955 with the model '175 CSS-5V'. The frame is the series "CSS" with a modified closed cradle, telescopic front fork and raised exhaust system. MV AGUSTA produced these '175 CSS-5V Regolarità Monoalbero' exclusively for the official MV Regolarità team. It definitely belongs to the most attractive MV machines ever built.
Between 1954 and 1956, MV AGUSTA achieved 17 wins in total with the '175 CSS-5V Regolarità Monoalbero'. MV pilot M. Fornasari won a Gold Medal on his '175 CSS-5V' during the International Six Days Trial (ISDT), and in general, the MV Agusta Team collected 7 victories.
The MV AGUSTA 175 'CSS-5V Regolarità Monoalbero' were never available on the open market. Between 1954 and 1956, only SIX (..!!!) machines were built, exclusively for the MV Regolarità ('Regolaristi') team. As far as we know, only two have survived. The finest one is owned by the Amsterdam Italian Motor Museum, who is in a beautiful condition and almost original, the other one is built together from spare parts and is far from original. That makes this MV AGUSTA 175 'CSS-5V Regolarità Monoalbero' a real treasure, a true gem that is missing in any serious MV Agusta collection around the world.
Only in exceptional cases, a copy was occasionally sold between private collectors in the past and as far we know, this is the first time an MV AGUSTA 175 "CSS-5V Regolarità Monoalbero" will be sold through a public auction. A unique opportunity to become the owner of one of the rarest and most unreachable Enduro machines.
The motorcycle manufacturer MV Agusta (originally Meccanica Verghera Agusta) was established in Gallarate a town near Milan, Italy on the 12 of February 1945. The AGUSTA brothers had a passion for mechanical works and for motorcycle racing. Much like Enzo Ferrari, they produced and sold motorcycles almost exclusively to fund their racing efforts. They were determined to have the best Grand Prix motorcycle racing team in the world and spared no expense on their passion.
