Harley-Davidsons are mostly associated with munching miles on the highway, and almost never with notable speed. But sometimes we come across a tuned and seriously fast Harley-Davidson that showcases the potential these hefty cruisers pack. One such is example is a 286-horsepower supercharged Harley, and further evidence is a turbocharged Harley-Davidson Road King Special built by YouTuber Bikes and Beards. It boasts tons of upgrades allowing it to outrun a Suzuki Hayabusa.

In its stock form, the Harley-Davidson Road King Special belts out 93 horsepower and 118 pound-feet from its 114ci (1,868cc) engine. Not too impressive, right? Well, the YouTuber thought the same and replaced the stock mill with Harley’s aftermarket Screamin’ Eagle 131ci (2,146cc) engine. As a result, the output figures on the dyno went up to a respectable 150 horsepower and 150 pound-feet. Most would be satisfied with this result, but Bikes and Beards went one step further and installed a turbocharger kit. To no one's surprise, the kit, along with other necessary upgrades - aftermarket cams, free-flow exhaust - increased the output to a whopping 223 horsepower and 217 pound-feet on the dyno. The only thing left? To take this beast out on the roads.

Though it was just a highway stroll to get a taste of the motorcycle, the YouTuber brought in a Suzuki Hayabusa to paint a picture of the turbo Harley’s performance. Now, this wasn’t a proper drag race or roll-on race on a closed road, but the results were mighty. The turbo Harley easily breezed past the Hayabusa in a couple of roll-on races, showing just how torquey it is regardless of the rev range. It’s worth mentioning the Suzuki will probably zoom past if there was a longer stretch of road and once it reached its full power band. Not to mention, the Hayabusa was bone stock, not even boasting an aftermarket can. Still, there’s no denying the tricked Harley Road King is a rowdy beast.
