The Triumph Bonneville Custom Revolution: Showcasing Global Creativity in 2025
In the world of motorcycles, custom builds have evolved from niche passion projects into headline-grabbing phenomena. In 2025, the spotlight shines brightly on Triumph’s legendary Bonneville lineup, as the iconic British marque organizes a global competition to uncover the most original Triumph Bonneville custom builds. This international showdown celebrates not just the Bonneville’s versatility but also pays homage to the artistry of custom motorcycle culture.
Triumph's Global Custom Build Competition: Participants and Vision
Earlier this spring, Triumph Motorcycles ignited the spirit of competition by inviting eight top builders from eight different nations — the United States, Canada, Mexico, Brazil, France, Italy, Thailand, and the UK — to push the boundaries of design for its flagship Bonneville models. Under the theme "Icons of British Originality," each team was tasked with transforming their chosen Bonneville while sticking to a select set of rules that ensured a level playing field and preserved the core heritage of the bike.
The judging panel is an all-star lineup from the world of custom motorcycles: Quique Berna (Tamarit Motorcycles), Ricardo Pessoa (Coolnvintage), Kengo Kimura (Heiwa Motorcycle), and Steve Sargent (Triumph Motorcycles). Initially, all eight contenders head to the main stage, but only five will advance to the final public vote, where the ultimate winner will be crowned at month's end.
Meet the Contenders: Eight One-of-a-Kind Custom Triumph Bonnevilles
American Innovation: Racing Spirit on the Bonneville T120
The U.S. entry, crafted by Triumph Indianapolis, channels the city’s deep-rooted racing heritage. Using the Bonneville T120 as a platform, this build bursts forth in a daring palette of electric blue and vibrant yellow, exuding race-inspired aggression and standing out as the most colorful of the lineup. The U.S. build is a testament to how racing DNA can redefine classic motorcycle lines.
Mexican Homage: A Tribute to British Icons
Representing Mexico, Aftercycles opted for the Bonneville Bobber as their base. This custom job is a clever salute to legendary British names. Look closely and you’ll find yellow stitching on the handcrafted leather seat, a tribute to Dr. Martens, while a Harry Potter-themed badge adds a unique touch to the throttle body. This build merges Mexican craftsmanship with subtle British influences to create a truly distinctive motorcycle.
Brazilian Aggression: The Gaijin Café Racer
Brazil’s Shibuya workshop brings "Gaijin" to the competition, breathing new life into a Speed Twin 1200. This is arguably the most aggressive build on the list, with a low-slung café racer stance, all-black livery, and an array of handcrafted parts — especially around the rear end. The Gaijin speaks to the fast-growing café racer scene in Brazil and showcases what happens when handcraft and boldness meet.
French Elegance: A Nod to History with Hail to the Twin
From France, FCR Original delivers "Hail to the Twin," a bespoke build based on the Speed Twin 1200 RS. This machine pays homage to the 1937 Speed Twin, featuring a completely reworked tail section to highlight the engine’s architecture. Details like hand-plated copper and delicate gold leaf work elevate this motorcycle into a rolling piece of art, perfectly blending French flair with British heritage.
Canadian Precision: Handcrafted Details on a Modern Legend
Canada’s Motos Illimitées chose the Speed Twin 1200 RS and gave it a thorough overhaul, introducing a custom exhaust system with hand-formed stainless-steel headers and a lowered handlebar setup. Visually, the bike dazzles with a graphite-and-gold color scheme, highlighted by hand-painted pinstriping and Triumph’s own heritage badging. This creation embodies precision engineering married to artistic attention to detail.
Italian Splendor: Milanese Elegance on the Bonneville Bobber
Hailing from Milan, Italy’s South Garage Motor transforms the Bonneville Bobber into a 1930s-inspired masterpiece. A bespoke frame, unique components, and custom fork design blend to project luxury, sophistication, and classic European charm. This Bobber is a rolling tribute to an era where style reigned supreme and riding was an expression of personal elegance.
Thai Artistry: The Zeus Custom Bonneville T100
Thailand’s entry, crafted by The Zeus Custom, reimagines the Bonneville T100 into what they describe as a ‘motorcycle god.’ It combines rugged wire-spoked wheels with chunky tires, a short custom exhaust, and intricate, hand-worked leather accents. This standout custom seamlessly integrates East Asian design elements with British engineering.
British Pride: The Sunraiser by Stockwell Design
Back home in the UK, Stockwell Design’s "Sunraiser" is a Bonneville T100 that dazzles with polished aluminum, stainless steel, and a luminous, uplifting color scheme. This build recaptures classic British optimism and mechanical ingenuity, radiating brightness and precision craftsmanship.
Exploring Specifications, Design, and Performance
While Triumph has not released every technical detail about the modifications, the base motorcycles — Bonneville T100, T120, Bobber, and Speed Twin 1200 — are legendary for their robust parallel-twin engines, agile chassis, and timeless design. Typically, the Bonneville T100 features a 900cc engine, while both the T120 and Speed Twin 1200 boast a powerful 1,200cc configuration. With torque-rich performance, responsive handling, and a wealth of custom-friendly architecture, these bikes are ideal canvases for creative transformation.
Each custom build in this global contest pushes the boundaries of what classic motorcycles can become. From racing-inspired exhausts to hand-hammered metalwork, and bespoke seats to radical frame modifications, the spirit of motorcycle customization is alive and well within this challenge.
Market Positioning and Global Appeal
Triumph’s Bonneville series already enjoys a devoted following thanks to its enduring British style, reliable engineering, and a strong heritage. The 2025 custom build competition further enhances its position in the global motorcycle market by demonstrating unparalleled adaptability. From North American hot rod ethos and European refinement to Asian innovation and Latin American creativity, the Bonneville continues to unite riders and builders across cultures.
How These Customs Stack Up
Whether compared against their standard equivalents or other contemporary custom bikes — such as Indian's Chieftain PowerPlus builds — these Bonnevilles showcase not just technical versatility, but also a thriving spirit of international collaboration and competition. Custom motorcycle enthusiasts can find inspiration in the way each nation interprets the same DNA, reflecting local style, motorbike trends, and performance values.
Judging Criteria and Next Steps
The panel of experts will evaluate all eight motorcycles based on Iconic Style, British Originality, Craftsmanship, and Creativity & Innovation. Only five builds will advance to the public voting stage, with the triumphant winner to be announced by month’s end. As the world watches, the next champion of Triumph Bonneville customization prepares to take center stage.
Stay tuned as we follow the journey of these extraordinary motorcycles, all vying to become the most original Triumph Bonneville custom of 2025.
