The two-stroke engine is mostly a piece of history today, but there was a time when some of the coolest developments in engine technology were two-cycle engines.

By the 1960s, the two-stroke engine powered superbikes in the GP World Championship. And like so many technologies developed by race teams, it found its way to the street.

On a two-stroke engine, however, the oil is "changed" more than 15 times a second — and that's only at idle. When it is up and running at 10,000 rpm, oil is cycled through the two-stroke engine ...
