Not to be confused with BMW’s original 750cc sidevalve R75 from WW2, the R75/5 boxer twin was manufactured from 1970 until 1974. The /5 series was the first model line to be manufactured in Berlin, as by 1969 all of BMW’s Munich plant capacity was needed for cars. In standard trim the R75/5’s chain-driven OHC 749cc engine was fuelled by two 32mm Bing carbs and it made 50hp @ 6,400rpm with 43lb/ft @ 5,000rpm. With a 4-speed gearbox and shaft final drive it weighed 210kg wet, and it was good for 110mph.
Using factory race parts, the Imola-spec racebike offered for sale here was prepared by Bonfino (Italy’s oldest BMW Motorrad dealer) to the same specification as works BMW rider Helmut Dahne’s. (Among other achievements, Dahne finished 4th for BMW in the 1972 and ’73 Isle of Man 750cc Production TT races.)
With a Fontana magnesium front brake and Ceriani forks, this BMW is also fitted with a large capacity alloy ‘endurance racing’ fuel tank, 35mm Dell’Orto racing carbs and electronic ignition. It competed in endurance events during the 1972 and 1973 seasons at Imola, Monza, Vallelunga and Barcelona, ridden by Menichelli, Tasso, Marchetti and Buscherini. The bike has Menichelli’s signature on the leather tank strap, but it was last raced by Tasso of Genoa.
More recently it has been raced by Tasso in classic bike meetings in France and Italy, and it has been in the same ownership since 2010. This sporting BMW boxer racer is presented in original, unrestored condition.
