This land speed car happens to be a Harley-Davidson Road Glide in disguise.

Projects tend to take on a life of their own. You start with a clear direction, only for things to suddenly spiral off course, plunging into chaos. That's part of the fun—and the source of many sleepless nights.

This is exactly what happened with Aaron Boss' Harley-Davidson Road Glidester.

For those unfamiliar, Aaron Boss is a skilled fabricator at Roland Sands Designs (RSD), a name well-known in the custom motorcycling scene. This particular project reflects RSD's love for the unconventional. It’s a blend of all Boss' passions: rat rods, 1950s land speed belly tankers, top-tier racers, and custom motorcycles.

And it looks absolutely bonkers.

"It's always been an idea in the back of my head," Boss explained over the phone. "I've loved belly tankers and Bonneville land speed records. We've built motorcycles that have set land speed records, and I wanted to tie everything I'm good at into one package. So, I built a chassis, suspension, and put a motorcycle engine in this thing for Bonneville. I know it started as a chopper show, but to be the first person to show up with four wheels at a chopper show—that's a statement."

Indeed, it is. Created for the Born Free show this June, Aaron Boss' Road Glidester draws from various disciplines, incorporating elements from aerospace and Formula 1 alongside hot rod heritage.

The design, inspired by post-World War II hot rods, is driven by a Pro-Charger supercharged Harley-Davidson Milwaukee Eight 117-cubic inch motor. Boss picked up a brand new Road Glide from Harley, drove it to his shop, and disassembled it completely.

"At first, I considered a BMW R 18 motor," Boss shared. "But when I got into the Born Free show, it had to be a Harley. I contacted Harley, they got excited, and they gave me a new 2023 Road Glide ST. I drove it five miles to my shop, tore it apart, pulled the motor, and started the build."

Boss handcrafted the Road Glidester’s frame, which resembles a mix of a top fuel drag racer, trophy truck, Formula car, and modern bunker buster bomb. "I try to use as many stock parts as possible," he noted. "The stock gauge cluster and controls look perfect in this chassis. I'm also going to make this street legal."

Yes, Boss wants to drive this on public streets.

"I'm in California, where street legal approvals are tough, but I'm determined. I’ll drive it around. If it's cool enough, most cops just pull you over to look at it," he said.

Beyond the V-twin engine, which now produces around 200 horsepower, the Road Glidester features a Winters Performance quick-change rear end, custom adjustable suspension, power steering, and a Baker six-speed transmission with a reverse gear. It also sports a roof scoop from a Dallara prototype.

Weighing about 1,200 pounds, it's lighter than Boss expected. "Roland Sands and his buddy could lift the front of the car. So, it’s pretty light," he said, adding, "I have carbon fiber and magnesium parts, which help reduce weight."

When asked about the project's completion, Boss laughed and said, "June 20th," just two days before the Born Free show. "If my suspension comes back from chrome today, I might have it driving by Monday or Tuesday," he added, a week before our conversation.

After Born Free, Boss plans to test it around town and at El Mirage for high-speed runs. "The car is so experimental. I have no clue how fast it’ll go," he concluded.
