'Bus' means a proper, air cooled VW transporter (excluding Vanagons & later). They stopped production in Germany in 1978 (1979, last model year of buses sold to America) but continued production in Mexico and Brazil after that.

The last YZ250 that was air cooled was 1981. 1982 is when they switched to water cooled engines.
