Years
1978 - 1985
The 1978–1985 BMW R 45 is the compact 473 cc boxer with shaft drive and air-cooled engineering. Check carburettors, valve clearance and oil leaks, final drive and brakes, plus frame, electrics and quality of any restoration or conversion.
The BMW R45 is the compact airhead boxer produced from 1978 to 1985. Its air-cooled 473 cc twin, shaft drive and five-speed gearbox deliver roughly 35 hp in a lower, lighter chassis than larger R models.
The R45 is an approachable classic for relaxed touring. It needs revs for pace and suffers when valve, carburettor or charging maintenance is neglected. Check twin front brakes where fitted, shaft play and frame/subframe condition; café-racer conversions often reduce originality.
