The R75/7 arrived in autumn 1976 when the /7 range replaced the /6, bringing the angular R90S-style 24-litre tank with a recessed filler and squarer rocker covers. Mechanically it kept the 50 hp 745 cc twin, and testers found it quicker than BMW claimed, with good brakes and comfortable touring manners. It lasted only about two years before the 800 cc R80/7 took its place.
