Previous model Yamaha RD 80 MX

The Yamaha RD 80 LC motorcycle is a light motorcycle from the Japanese motorcycle manufacturer Yamaha .

history

The RD 80 LC-1 appeared in 1982 as the successor to the air-cooled Yamaha RD 80 MX . Because the seat was too short, the LC-1 was only approved for one person in Germany, which meant that the model did not sell well and was soon offered at very affordable prices. Later, Yamaha delivered a replacement seat including a second footrest system and certificate free of charge, which could accommodate two people (uncomfortably). Only 4260 pieces of the LC-1 were registered in Germany.

In 1983 the larger RD 80 LC-2 was released, which was approved for two people from the start and was based on the RD 125 LC both visually and technically.

technology

The RD 80 LC is a light motorcycle with a water-cooled two-stroke engine. It has a disc brake at the front and a drum brake at the rear. There were the following models:

  • Type 10X (Yamaha RD 80 LC-1, model year 1982–1984), 6 kW / 8.2 PS, single-seater, top speed 80 km / h, 6-V electrical system
  • Type 30W (Yamaha RD 80 LC-2, year of construction 1983–1986), 7.2 kW / 9.8 PS, two-seater, top speed 80 km / h, 12 V electrical system

The Yamaha Energy Induction System YEIS, an external reservoir that is connected to the inlet channel by a hose, also comes from the RD 125 LC. The mixture should get into the combustion chamber at a higher and more even speed, which in turn should improve the filling. Yamaha spoke of 10% fuel savings and more torque in the lower speed range. Furthermore, both versions of the RD 80 LC had the Autolube system, which made mixing tanks superfluous, a maintenance-free CDI ignition and a cantilever box swing arm with central spring strut.
