Rick’s Motorcycles once again showcases its expertise in the art of customization with this aggressive and refined take on the iconic Harley-Davidson Fat Boy.

This build is all about muscle, presence, and premium components, turning a classic cruiser into a head-turning custom machine.

At first glance, the massive 300 rear tire sets the tone, perfectly integrated with Rick’s Mono Swing Arm and a custom rear fender, engineered to match the wide tire’s brutal stance. Rolling on Rick’s signature forged Mono Block wheels, this Fat Boy commands attention from every angle. The front end features a 23″ wheel, complemented by Rick’s custom front fender, giving the bike a perfectly balanced and aggressive silhouette.

Performance and handling are matched with premium details. Rick’s wave brake discs ensure powerful stopping performance while enhancing the overall aesthetic. The axle cover kit adds a clean, refined finish to the wheels and suspension components.

One of the most striking visual upgrades is Rick’s stretched gas tank, seamlessly integrated into the Fat Boy’s frame for a longer, lower look. Combined with the Custom Chrome Europe handlebar, the rider’s position is both commanding and comfortable.

Lighting and electronics are taken to the next level with ultra-compact yet powerful Kellermann ATTO turn signals, blending minimalism and visibility with German precision.

This Harley-Davidson Fat Boy is more than just a custom bike – it’s a testament to Rick’s Motorcycles’ commitment to craftsmanship, style, and performance. Every component is carefully chosen and flawlessly executed, making this build a true standout in the world of custom Harley-Davidsons.
