I was trying to find a list of the years each of the Harley Davidson motor types were produced.  Checked the H-D website and couldn't find it.  Anyone know where to find this?

Here you go Drake.  Here is a list of all the Harley engines, and their production periods.  Each of these motors had a couple of different variations during their production.

Flathead: 1909-1936

The Flathead was named because of the tell-tail flat vented tops that are recognizable at the top of each cylinder head. This is the famous motor that propelled the Harley-Davidson to victory after victory in the motorcycle races of the twenties.

Knucklehead: 1936-1947

On the eve of WW2, Harley-Davidson introduced an overhead-valve V-twin with knuckly looking valve covers. The new motor, affectionately named the "Knucklehead", performed well both for HD and for America in the difficult years to come.

Panhead: 1948-1965

WIth improvements to engine design, like hydraulic valve lifters that supplied oil through rocker arms, the Panhead hit the market in 1948. It was named for the pan-like valve covers replacing the knuckle covers.

Shovelhead: 1966-1983

By 1966 the Panhead underwent still more improvements. The most noticeable being the distinctive enclosed cylinder head in a sleek, slightly curved top. At a glance this looks unmistakably like a shovel with the pushrods tubes resembling the handle of a shovel, and the shovel itself.

Evolution: 1983-1999

In 1984 on the heels of a bold employee buyout of AMF, the motor company went public and introduced its now famous redesign of the V-twin. This radical new design utilized styled square blocks to house the valve train. This motor, revered as the Evolution engine is known amongst Harley enthusiasts as "the Blockhead".

Twin Cam 88: 1999-2006

With numerous American motorcycle manufacturers trying to surface and resurface, Harley-Davidson introduces its most revolutionary engine yet. The Twin Cam 88 gets its name from its two cams versus the single cam in all its ancestors. This motor also goes by the nickname "Fathead" for just exactly that, bigger heads. With this new engine design Harley-Davison puts one more notch in its insurance for success.

Twin Cam 96: 2007 - Present

With an increased demand for a more powerful engine, Harley increased the size of their famous twin cam engine from 88 ci to 96 ci.

Twin Cam 103: 2011 - Present

Harley increases the power again this time to 103 ci.  As of 2011 the 103 motor will be stock in all Harley Davidson Touring model motorcycles. The new 103 ci engine also includes an integrated Oil-Cooler.

Just saw this...Very nice list. I am always getting asked, what was made when, I gonna print it out and put it on my shop wall. Thanks Lucky

very informative well written. u should write for a mag...

Never saw this post...good stuff!

One more engine to add that is the debatable VRod or Revolution engine.

The Revolution engine is based on the VR-1000 Superbike race program, developed by Harley-Davidson's Powertrain Engineering team and Porsche Engineering in Stuttgart, Germany. It is a liquid cooled, dual overhead cam, internally counterbalanced 60 degree V-twin engine with a displacement of 69 cubic inch (1130 cc), producing 115 hp at 8250 rpm at the crank, with a redline of 9000 rpm. It was introduced for the new V-Rod line in 2001 for the 2002 model year, starting with the single VRSCA (V-Twin Racing Street Custom) model.

Don't forget the new water cooled head motor on the Ultras

So the 04 and up Sportster has a new engine developed in 04 based on the Buell. Now how doe it fit in? Since the 1200 C and R have larger valves than the other Sportsters. Would they classify as 2 different motors or 1? The Sportster introduced in 1957 and still going strong had a different motor than any other Harley.

I don't believe my eyes so clear and descriptive information.......good stuff.
