First seen on UK roads back in 1974, the RD125 shared much in common with its predecessor, the Y-AS3. Featuring an air cooled twin cylinder 125cc engine with 5-speed gearbox, drum brakes front and rear and a conventional steel tube frame and rounded petrol tank.
The RD125 was a stylish little bike with excellent performance for its size. The later RD125DX featured a square tank and updated colour schemes, plus a disc brake at the front with cast alloy wheels as an optional extra. The final RD125LC introduced in 1981 was a totally different motorcycle with a single cylinder liquid cooled motor and much more modern chassis.
