SOLD – 1921 -24 Harley Davidson D Model Engine cases – The Big Twin or Model 1925


1921 -24 Harley Davidson D Model V-Twin Engine cases and pair of connecting rods.

“The Big Twin” or Model 1925 was introduced in 1921 as the D-model. In 1925, the E-model came along. This is for the 74 Cubic inch motor.

As the engine number is D727, I think this is fairly on in the production of the D model.

The two halves have matching numbers. So, it’s nice to know this is an original pairing.

I only have the cases and the connecting rods. The conrods have the big end bearings. The conrod numbers are:

  1. DE18/5
  2. DE17/6

The cases are in good condition overall, with a very light amount of oxidisation on the primary drive side. The top / forward engine mount has been repaired. It’s not pretty but it’s functional. It could do with tidying up.

International shipping available.

Viewing: Please come and check it over before you buy. It is at PE28, near St Ives in Cambridgeshire.
