Introduction to the RD125LC. part 1 -  RD125LC, 10W &12A, (mk1)
The new Yamaha RD125LC was first announced to the press in the winter of 1981/82, A new single cylinder, liquid cooled motor. introduced in June 1982. The new UK learner laws were changing from 250cc to 125cc / 12bhp restrictions in 1982/83. There was going to be a big new market for the 125cc machines. The new 125LC was born, styling inherited from the latest RD250/350LC's, Nose Fairing, Belly pan & more sportier looking than the earlier RD125 aircooled twins it replaces to keep pace with the current trends. Colours available were White or Candy Blue for early models, later colours introduced to the line up in 1984 were Red or Black or White with larger sportier Red & Blue Decals.
 Fuel consumption as tested by BIKE magazine in December 1982 was between 76-79 mpg
The Price in 1982 for a 125LC  was just £820 but back then it was high price for a 125cc bike. Yamaha's only main rival in the beginning was from Kawasaki with the liquid cooled AR125, the AR had the better mid range power with its reed and rotary disc induction system, whereas the RD had the edge on top end power and easier to tune. The RD was the bike to have.
