A Harley Takes an Engine From Porsche. NO wonder many riders don't know what to make of the new V-Rod from Harley-Davidson: The engine was designed in Germany by Porsche and it has the first water-cooled engine in Harley-Davidson's 99-year history. The V-Rod doesn't look like any other Harley.
In 1995, Ford axed its venerable pushrod 16-valve V-8 for a V-8 that still had just 16 valves but now ran with a pair of overhead cams. Keeping the pushrod seemed like yet another example of the General's hanging on to its glory years. But since then, I've come to see that, for a mass-produced V-8 engine, the pushrod layout has more advantages than disadvantages. Power is a function of airflow, pure and simple, says Winegarden.
