The Honda CD175 was a 174 cc (10.6 cu in) Honda motorcycle made from 1967 to 1979. It was the touring model in Hondas 175 cc motorcycle lineup that also included the sportier CB175 and the off road CL175 version. The CD175 shared many components and design elements in common with the contemporary CD125 and SS125 models from Honda including stamped t-bone frame, swingarm, double seat, and electrics among other things. It had electric start, except in the UK, turn signals, and mirrors. The sloper engine used on earlier models was an evolutionary version of the older Honda CB160 power plant and contained many of the same components including most of the castings and internal items. The CD175 had a 360° crankshaft, wasted spark ignition, single carburetor, a parallel twin high revving engine, 16 wheels and a 100 mph (160 km/h) speedometer. Each connecting rod big end had roller bearings. In 1979 it was replaced by Honda CD185. SpecificationsEdit Years of Production 1967–1979 1967 models (product code 237) began at serial number CD175-1000001. Also known as the CA175, CD175A, or CD175 K0 just over 17000 of these units were built and distributed worldwide although only to commonwealth countries. Styling and appearance on these early CD models was similar to the larger CB450K0 Black Bomber, especially the British version which received a set of low-rise handlebars (as well as no electric start and different winker positions). 1968 models (also product code 237) began at serial number CD175-10017136 and incorporated changes that allowed for export to the USA. These changes included a different fuel tank with larger, less pointy chrome covers and knee pads, larger more bulbous battery and tool covers, upgraded lighting and signals/switches, and a hybrid welded-tube/stamped frame. The engine remained unchanged from 1967. 1969 K3 models (product code 302) introduced the vertical engine and all-tube frame and some smaller body work changes that continued until the end of production in 1979.
