JD Cut-Down vs Stock

 I was just curious about comparing the two side-by-side, stock vs Oppie cut-down.

Sam Oppie a founding member of the Seattle Cossacks stunt riding team was to become one of the most prolific exponents of the two cam cutdown. Usually finished in Robins egg blue, Oppie maybe built as many as 20 of his uniquely modified specials. The front downtube was reshaped to bring the engine forward for better weight distribution. The seat post was lowered 2 inches, creating a shorter backbone, that then required the gas tanks to be shortened as well.
