Origins
The Yezdi Roadking was originally based on 1974 CZ,where the original bore and stroke of 70 millimetres (2.8 in) / 64 millimetres (2.5 in) was retained as it was, but with less power than its Motocross original. The engine block is smaller and different from the Yezdi Classic in appearance. Also the CZ original had the famous Porcupine Head while the same was used only in initial models, later reverted to regular straight fin design. The cylinder block (Type 980.5) was from CZ.

Chassis frame
The chassis frame is single frame of motocross origins and was built out of square tube. The fork was more pronounced with a higher rake angle and came with adjustable shock absorbers. Rims were 16 inches. The motocross and ice racing origin frame and proper weight balance made handling very easy and agile compared to its rivals in India.

Engine
The cylinder block was from CZ which had an over square bore x stroke. Carburetors were either Jikov (tickler choke) or Pacco (press type choke) of which the earlier was exclusively for Roadking, while the latter was used for Classic models. The spark plugs were of cold type and the bike also featured a semi-automatic or auto clutch, where a cam inside the gearbox housing automatically activated the clutch through a cam which is unique to this and other Yezdi models in India. The familiar Jawa-CZ twin exhaust ports made the unmistakable sound when the exhaust flute mufflers and end-cores were removed. Another unique feature of the bike was that the kick-starter and the gear shared the same rod as with all Yezdi models. Once the gear rod is reversed it doubles as a kicker and once started it automatically returns to the original position. The lever has an intenal cam which engages/disengages the clutch when you shift the gear thereby precluding the need for a hand-clutch.
