In 1955, MV Agusta designed the 175 CSS-5V for the 175 cc "Formula Sport Derivata" race series. The “Squalo” (English: shark), as it was generally known, had a lighter frame based on that used on the works racers, larger brakes, a magneto, Earles forks and a five-speed gearbox. The bike became the part of motorcycle racing history thanks to the first victory of young Mike Hailwood, the future nine-time world champion. Mike won his first ever race on one of these machines bored out to 196 cc in a 200 cc class race at Oulton Park in 1957. Around 200 of the model were manufactured between 1954 and 1957.
