If you're anything like myself, the thought of well-orchestrated motorcycle literature with glossy, two-page spreads and endless technical specs is enough to make your heart flutter with eagerness (come on, admit it). If vintage Harley-Davidsons are your thing, then I'm sure you're well familiar with the iconic EL model, otherwise known as the Knucklehead. But do you have an intimate understanding of this historic machine? Do you know everything there is to know about every single model from every single year? Wouldn't it be fun to stump your friends with the minute differences in the rocker shaft ends and oiling in the lower end?

If you're willing to accept that metaphorical sword of knowledge, then Harley-Davidson Knucklehead: Eighty Years is definitely for you. You're sure to be the envy of your friends when you win the bet as to who can name the most factory color options from 1936 (hint: there were 5). But wait, there's more! A lot more, actually — almost 200 pages of facts about production costs, model differences, aftermarket options and so on. Not only that, but incredible, high-resolution shots of everything from original-paint production models to the streamlined EL-powered racer that set the speed record on a Florida beach in 1937.

There’s enough information inside to keep you entertained for days, weeks, or years even. Author Greg Field’s wording keeps the subject matter captivating and refreshing, despite the intimidating nature of the immense breadth of data. There’s no question about it though; Harley-Davidson has become a staple of American culture, and what better way to understand their rise to distinction than gaining a familiarity with a bike that marked a pivotal turning point for the company?
