of paper with the freedom to design what he wanted. When Cagiva sold Ducati to the Texas Pacific Group in 1996, Tamburini elected to stay with Cagiva, citing as his reason, "Cagiva is my family". The F4 was equipped with an inline four cylinder 749.5 cc engine with radial valves. It produced 126 hp at 12,500 rpm and 72 Nm at 10,500 rpm. The maximum speed was 275 km/h. But probably the most unique feature was the design: the F4 was even exhibited in the Guggenheim Museum in New York during the Art of the Motorcycle exhibition from June 26 to September 20, 1998. The exhibit list included 95 of the most outstanding motorcycles of all ages. And four of them are MV Agusta brands. The fifties and sixties of the 20th century were represented by two grand prix 500 cc prototypes of the MV Agusta (1956 and 1968 seasons), the first half of the 1970s – by the MV Agusta 750 S (1973), and the late 1990s – the MV Agusta F4 750 (1998). The success of the exhibition was so significant that the museum repeated it twice more: in its branches in Bilbao and Las Vegas. The subsequent process of industrialisation was divided into two distinct stages: the first with production of a limited run of 300 F4 Serie Oro (English: Gold Series) bikes, with carbon fibre bodywork, magnesium parts and an engine with sand cast crankcases anticipating the construction of the S model, destined for a broader range of users thanks to its price, cut by half over that of the previous version. With just minor improvements the F4 750 was in production until 2004, when it was replaced by the F4 1000. At the same time, in addition to the regular versions of the 750 cc sports bike (S, S 1 + 1, S EVO2 and S EVO3), number of special editions were also produced: 140 hp Senna in 2002 (in memory of the legendary Brazilian racer Ayrton Senna) and 146 hp SPR / SR in 2003 (with improved cylinder head, intake and exhaust). Each special edition was limited by 300 units. 2004–2016: Time of changes In December 2004, in spite of the fact that MV Agusta became the main brand of Cagiva group, due to cashflow problems Claudio Castiglioni was forced to sell a bigger part of his stake in MV Agusta (65% of the
