Honda introduced several 200 cc motorcycles with similar engines but different body variations in the 1980s. The model introduced in South Africa and Pakistan was known as the CD 200 RoadMaster. It had a twin cylinder 10-degree cylinder angle with a 360-degree crank shaft angle engine which meant the pistons moved together and reached top dead centre (TDC) and bottom dead centre (BDC) at the same time. It was a detuned version of the Honda CD185 twin. The engine had the same bore as the CD185 but low compression pistons (8.8:1) with a bore and stroke of 53.0 mm × 44.0 mm (2.09 in × 1.73 in), compared to 9.0:1 Compression and 53.0 mm × 41.0 mm (2.09 in × 1.61 in) for the CD185.[4] The result was less power, a higher fuel economy and a lower top speed. The alternator system was also different from the CD185.[12] Apart from this the models were much similar, using the same frames, suspension,[8] wheels, tyres, and brakes.[9]

The CD 200 featured a square speedometer, large front and rear mudguards, twin chrome exhausts, a choke tucked in behind the handle bars, a chrome plated fuel tank with the Honda logo and mock chrome air inlets on side panels. It had drum brakes in rear and front[9] and a single 26 mm Keihin carburettor (PD 33A TA). It weighed 140 kg (310 lb)).

The CM200T (also known as the Twinstar) was a twin cylinder motorcycle produced by Honda from 1979 to 1984 as part of its factory "Custom Motorcycle" lineup. The CM200's design was based on the CD200 Benly/Roadmaster, using the same engine, transmission, frame, and brakes.[13] It had a speedometer that read up to 80 mph/130kmh, with markings indicating the maximum speed for each gear ratio. Another instrument panel had lights for Neutral, Indicators and High Beam, but no tachometer was provided.

Power was around 16 bhp, which gave the CM200T a top speed of around 71 mph (114 km/h), although a popular modification was to change the front gearbox sprocket from 15 to 16 teeth which increased top speed to around 75 mph (121 km/h) given good conditions, and could comfortably cruise at 60 mph (97 km/h).

The Twinstar used an odd combination of tyre sizes (3.00-17 front and 3.50-16 rear)[9] which can make branded replacement tyres expensive, although Chinese tyres are still available at reasonable prices.

The engine was a 194cc parallel twin and had a 360 degree layout that used a single ignition coil and single round-slide carburettor. Early models used a 6 V electrical system with contact breaker/condenser ignition, whereas later models used a 12 V system. All models had a 4-speed manual transmission.
