The original CG125 was built in Japan from 1976 as a tough, cheap commuter for developing markets, using a pushrod OHV version of the CB125 single that tolerated neglect. A foam air filter and fully enclosed chain kept maintenance low. In the UK it became a learner favourite, returning around 100 mpg, though its drum brakes and dim direct lighting were basic.
