When Ducati launched the the first-generation Monster bikes - the M900 in 1993, the M600 in 1994, and the M750 in 1995 - it paved way to a new line of naked street fighters that was to become a Ducati staple in the coming years.
The Monster was designed by Miguel Angel Galluzzi, who built the bike at the behest of Massimo Bordi. He once said that this bike was what Marlon Brando would have ridden in The Wild One, had he been able to get one.
The Ducati Monster then paved the way for this particular bike, the Monster S4R, which made its debut in 2001 packing a 916 cc liquid-cooled DOHC Desmo V-twin engine with a six-speed transmission, semi-floating Brembo disc brakes, light wheels, and Showa inverted forks.
This particular bike is the actual test mule in which the 916 motor was fitted, when the project was being developed. It’s extremely rare for a developmental bike to come to market, especially one with such an obviously low set of matching numbers.
At the 2012 RM Auctions in Monaco, the bike was sold at a price of €2,340, which is about $2,900 based on current exchange rates.
