After only three years BMW's '/6' line-up was replaced in the autumn of 1976 by the '/7'. The R90S-style fuel tank (adopted across the range) and redesigned rocker covers were distinguishing features while at the top of the range, 980cc R100 models replaced the '90' series.

Offering, arguably, the best compromise of power and economy, the R75/7 turned in an impressive performance when tested back in 1977 by Bike magazine, which reckoned it was faster than its maker claimed. The big BMWs have always been consummate touring motorcycles and the R75/7 came fully equipped for the job, boasting 'a stainless disc that stops you in the wet, superbly comfortable riding position and well-damped long-travel suspension, over 250 miles on one tank of fuel, the brightest headlamp in the business...' No wonder Britain's best-selling motorcycle magazine liked it so much.
