Question
Hey Mike this is Brad Streight of Odenton,Md.and I'm about to embark on restoring 2 H-D Motorcycles and I want to be as accurate as possible especially torwards the right specifications and engines to both a 1955 H-D Hummer and a 1956 H-D K-KH. 1.)Can you tell me what size and type engines they used on both models? 2.)And the same torwards their frames? Why,I'm looking to make reproductions to the 2 H-D Motorcycles that Elvis Presley owned and perhaps in knowing this,it might be able to help you with the answers! Sincerely,Brad Streight

Answer
For the hummer they made a 125 and a 165 CC model. Both were single cylinder and 2 stroke. On the K model they didnt make a KKH. they made a K model and a KH model. the K model was a 4 stroke 45 cubic inch and the KH was a 55 cubic inch 4 stroke. What did you want to know about the frames?
