First introduced in 1957, the Sportster line of Harley-Davidsons is one of many iconic Harley models still around today. Originally equipped with a 55 cubic inch overhead valve V-Twin, the Sportster has long been the “performance” Harley.

When the Harley-Davidson Softail first hit the scene in the mid-1980s, it debuted the 1340cc Evolution engine – the most advanced Harley-Davidson engine yet. The Softail also hid the rear shock, a clever design element to give the appearance of a hardtail, without the discomfort.

When you think of Harley-Davidson, one of the many things you think of is touring bikes. The FLT range really kicked that off in 1980 and continues to innovate in the touring world today.

Harley-Davidson’s recent attempt at a low-cost, entry level motorcycle, the Street 500 and Street 750 siblings are powered by a new Revolution X engine with a six-speed transmission. As is common with today’s global economy, parts are sourced from global suppliers with final assembly (at least for the US market) occurring in America. Other markets will see production and manufacturing for the Street line occur entirely in India.

The Milwaukee-Eight project introduced a new V-Twin to the Harley-Davidson lineup, now with four valve heads, a single camshaft, and–get this–liquid-cooling!

Harley-Davidson becomes the first major manufacturer to tackle electric motorcycles with this, the Livewire. A project many years in the making, the Livewire is Harley’s halo project, meant to demonstrate what to expect from The Motor Company in its future of electrification.

Looking towards the future, Harley-Davidson finds itself diversifying, heading into the streetfighter market with this, the Bronx. Powered by a 975cc Revolution Max V-Twin, the 60-degree V angle is liquid-cooled and claimed to make more than 115 hp and 70 lb-ft.

Harley-Davidson is also looking to tap into the popular Adventure-Touring market with this, the Pan America. Powered by a 1250cc version of the Revolution Max V-Twin, Harley is claiming more than 145 hp and 90 lb-ft. of peak torque.
