Visually; cast iron for the peasants and aliminium for the better folk$$
Ha Ha!!
The aluminum heads (in either medium or high compression) were an extra cost option. They do look good though!

Many U models in the '42-'45 era started life as Military bikes. ULs were civilian models, mostly for police use although a few were used by private owners.
My '44 UL is in police trim.
