Since its debut in 1957, the Sportster engine has had an exceptionally long lifespan, even by Harley-Davidson's impressive standards.

Significant updates were introduced in 1986, bringing transformative improvements to the model.

In 1986, Sportsters embraced Evolution technology, similar to the advancements seen in Big Twins two years prior, resulting in a more refined and dependable engine compared to its predecessor.

The updated engine was offered in two sizes: the classic 883-cc and a more robust 1,100-cc variant, with the latter expanding to 1,200-cc by 1988.
