When you think of a Harley-Davidson, I would presume most people would picture thunderous motorcycles cruising down the highway. But what if you took the soul of a Harley-Davidson, its massive V-Twin engine, and transplanted it into a car? Many people might have attempted this, but I can bet you have never seen anything like this. A famous designer from Roland Sands Design is currently transforming a Harley-Davidson motorcycle into a one-of-a-kind high-speed car.

The Harley-Davidson Powered 'Glidester' Is Being Built For Bonneville Speed Runs

Meet Aaron Boss, the unsung hero and motorcycle designer extraordinaire at Roland Sands Design. Aaron has been tasked with transforming Roland Sands’ audacious visions into reality, but right now, Aaron has outdone himself yet again with this crazy custom build. This time, his project is a one-of-a-kind amalgamation of motorcycles and automobiles, going from two-wheels to four-wheels. Dubbed the "Road Glidester" or "Hogster", this is an open-wheel roadster powered by a beast of a machine - the Harley-Davidson Milwaukee Eight 117-cubic inch motor.

This massive V-Twin used for the project was originally nestled within a 2023 Road Glide, but it now serves as the pulsating heart of Aaron's latest creation. We can only assume that this wasn't what Harley-Davidson anticipated when they delivered a pristine bagger for a routine custom job. Instead, Aaron took a bold leap, crafting not just a modified bike, but a wholly original car.

There were no concrete plans, and he had to look for help from others when it came to parts. But everything else was built or crafted by him. From the F1-style chassis and sprint car gearbox to the hand-shaped body work, all of this was conceived and executed by Aaron's skilled hands.
