A for antique
Mini’s magic lay in the four-speed gearbox mounted in the sump; a contemporary motorcycle innovation. The four-cylinder A-series dated from 1951’s Austin A30, with three main bearings and iron block and (non-crossflow ohv) head. Mini unit displaced 848cc; with single SU carb it gave 25kw at 5500rpm and 60Nm at 2900rpm. 0-60mph (97km/h), at 26.5 seconds, was still five seconds quicker than a Triumph Herald.
