The Harley-Davidson FLFBS 1868 Fat Boy 114 “Fat Man” by Bündnerbike is a powerful statement within the world of custom motorcycles.

The Harley-Davidson Fat Boy has always been an undisputed icon of the fat custom scene, representing strength, presence, and timeless design. It has always been that way, it remains so today, and it will continue to be a benchmark for generations to come.

However, a Fat Boy is never just a Fat Boy when it enters the workshops of Bündnerbike. This legendary platform is taken to a completely new level, transformed through precision engineering and bold design choices. The “Fat Man” is a perfect example of how a classic Harley-Davidson can be fully reimagined without losing its original soul.

One of the most striking features of this build is the massive 23-inch front wheel, which immediately dominates the bike’s visual profile. Perfectly matched with the FAKT-tested Bündnerbike chassis, the result is a flawless balance between aggressive aesthetics and stable road performance. The special black matte paint finish enhances every line of the bike, giving it a stealthy and muscular appearance.

At the rear, the bike features a Bündnerbike 3D rear conversion with integrated LED lighting, creating a clean and modern look. The build is further elevated by a Bündnerbike air suspension system, fully FAKT-approved, allowing the bike to adapt its stance while maintaining legal road compliance.

Custom details continue with the Bündnerbike 3D fuel tank and an MFK-approved Bündnerbike air filter, combining performance, reliability, and refined craftsmanship. The wheel setup consists of an 18-inch rear rim and a 23-inch front rim, reinforcing the Fat Boy’s unmistakable fat custom character.

A handlebar conversion improves both ergonomics and control, while the Dr. Jekill & Mr. Hyde exhaust system delivers adjustable sound and performance, perfectly matching the bike’s dominant personality. The side-mounted license plate holder cleans up the rear profile, keeping the overall design sharp and aggressive.

Finishing touches include Harley-Davidson grips and footpegs, a handcrafted leather saddle, and fully black-coated attachments that complete the monochromatic black-on-black theme. Every component has been carefully selected to contribute to a cohesive and powerful final result.

The Harley-Davidson Fat Boy 114 “Fat Man” by Bündnerbike is more than a custom motorcycle. It is a rolling work of art, built to conquer city streets and stand out in the international custom scene as a true symbol of craftsmanship, attitude, and exclusivity.

IRON MESH is a striking reinterpretation of the Harley-Davidson Breakout 117, meticulously modified by Bündnerbike.

This custom cruiser delivers a powerful visual presence, advanced technology, and full road legality, making it as capable on the street as it is impressive at a standstill. Built for riders who value performance, design, and exclusivity, IRON MESH stands as a modern custom icon.

The extended fuel tank stretches the bike’s silhouette, giving it a longer, more aggressive stance while enhancing the sporty proportions of the Breakout 117. A flush-mounted pop-up fuel cap keeps the surface clean and uninterrupted, preserving the minimalist design while remaining practical and easy to use.

At the rear, the flowing fender seamlessly integrates the seat and LED lighting into a single, cohesive unit. The modern LED system provides excellent visibility with a distinctive light signature, while the slim tail section elegantly frames the wide rear tire and delivers a powerful, uncompromising rear view.

The fully adjustable air suspension, certified by FAKT, allows the seat height to be tailored for show, comfort, or sporty riding. When parked, the bike sits low for maximum visual impact, and once in motion, the suspension automatically raises to ensure optimal ground clearance. This system offers proven quality, reliability, and intelligent functionality without compromise.

A side-mounted license plate holder developed by Bündnerbike reinforces the clean and muscular look of the rear end. Custom-made and tool-free interchangeable, its minimalist design keeps the bike visually ordered and aggressive, free from unnecessary elements.

CNC-machined aluminum hand grips by Bündnerbike provide a secure grip, precise control, and a premium tactile feel. Their ergonomic shape and high-quality finish reflect the machine aesthetics that define this build. Matching CNC-machined foot pegs for both rider and passenger offer excellent stability and comfort, combining durability, functionality, and refined style.

The handcrafted leather seat features elegant diamond stitching and a sporty silhouette, delivering long-lasting comfort and a refined appearance. A distinctive detail is the stitching color, precisely matched to the green accents of the bike, subtly tying the entire design together and elevating the overall aesthetic.

A fully integrated passenger seat with backrest ensures ergonomic support and safety while maintaining the custom look. It offers true touring comfort without sacrificing the clean, performance-oriented design of the motorcycle.

Performance and sound come together through the combination of a KessTech electronically controlled exhaust system and a Bündnerbike high-performance air filter. The KessTech exhaust offers variable sound characteristics at the push of a button, ranging from discreet to aggressive, while remaining fully street legal thanks to EC and ABE certification. The specially developed Bündnerbike air filter maximizes airflow and noticeably improves performance, combining technical efficiency with a bold visual presence.

Together, the intake and exhaust form a perfectly balanced system, delivering unrestricted airflow on intake and adjustable sound on exhaust. The result is a riding experience that can be precisely tuned both technically and acoustically, remaining legal, powerful, and truly unique.

Visually, IRON MESH is defined by the contrast between deep gloss black and vivid toxic green. The high-gloss black fuel tank is accented by a bold green Harley-Davidson logo, creating an instantly recognizable and iconic look. Matching green powder-coated engine covers are heat-resistant and precisely aligned with the tank design, emphasizing the build’s attention to detail and quality. Gloss black powder-coated wheels and components complete the finish, offering both elegant appearance and exceptional durability under demanding conditions.

IRON MESH is more than a custom Harley-Davidson Breakout 117. It is a statement of design, engineering, and controlled aggression, created for riders who demand individuality, performance, and presence in equal measure.
