Model K Series
This is developed from the earlier 45 W model, but with the revised flat head engine and new 4-speed transmission contained in the same castings as would become the Sportster. The connecting rods would be inherited by the Sportster along with many other design features and dimensions.
- Model K and KK 1952–1953: 750 cc side-valve engines, using the 45 model bore and stroke
- Model KR (racing only) 1953–1969: 750 cc side-valve engines
- Model KH and KHK 1954–1956: 885 cc side-valve engines, using the 45 model bore, but with the stroke increased to 4.5625" (115.89 mm). This is the only small twin with a longer stroke than 3.8125", which is otherwise universal to the entire 45/K/Sportster line from 1929 to the present (exception: XR750, XB9 Buell).

Famous quotes containing the words model and/or series:
“The best way to teach a child restraint and generosity is to be a model of those qualities yourself. If your child sees that you want a particular item but refrain from buying it, either because it isn’t practical or because you can’t afford it, he will begin to understand restraint. Likewise, if you donate books or clothing to charity, take him with you to distribute the items to teach him about generosity.”
—Lawrence Balter (20th century)
“As Cuvier could correctly describe a whole animal by the contemplation of a single bone, so the observer who has thoroughly understood one link in a series of incidents should be able to accurately state all the other ones, both before and after.”
—Sir Arthur Conan Doyle (1859–1930)
