Triumph Bonneville T120: the accessories and build guide

The Triumph Bonneville T120 is the direct heir to the legendary Bonneville: the premium neo-retro roadster of the range, the one that embodies the essence of the classic British motorcycle with Triumph's modern technology. At FCR Original, a workshop specialising in Triumph Modern Classic since 2012, it is one of the bases we build most often. This complete guide covers the T120's technical specifications, its different versions and above all the catalogue of FCR Accessoires parts developed for it: exhaust, French-made custom seat, approved lighting, braking, suspension and detail solutions. Every part is designed and tested in our workshop, plug and play, with no irreversible modification to the motorcycle.

Triumph T120 technical specifications

The Bonneville T120 holds a special place in the Triumph range: it is the flagship version of the Bonneville family, the one that pushes the balance between style, comfort and versatility the furthest. Where the T100 favours accessibility, the T120 steps up with its 1200 twin and a richer specification.

Its engine is the Bonneville 1200 HT parallel twin, built for low-end torque rather than top speed. The result: smooth, torquey and reassuring riding, ideal both for daily use and neo-retro touring. It is also an excellent build base, as its heritage silhouette lends itself to many styles, from vintage roadster to elegant custom.

The T120 versions

The T120 comes in several versions. They all share the same technical base, which is excellent news for accessories: the parts developed for the T120 are compatible with all these variants.

Triumph Bonneville T120

The reference version. An authentic classic roadster, it relies on chrome, British elegance and timelessness. It is the ideal base for a premium vintage build, a neo-retro touring bike or an elegant custom that keeps the original Bonneville spirit.

Triumph Bonneville T120 Black

The T120 Black keeps the T120's technical base but adopts a more modern, assertive personality: black engine and exhausts, darkened finish elements, stronger visual presence. A more aggressive look, perfect for a cafe racer, a blacked-out build or a minimalist custom. It is an excellent base for FCR Original's most modern builds.

Triumph Bonneville T120 Elvis Presley Limited Edition

The most exclusive version of the family. A limited collector's edition, it celebrates the historic link between Elvis Presley and the Bonneville, with a specific livery, individual numbering and exclusive finish elements. On this collector model, we favour light personalisation and discreet optimisation that preserve the bike's value rather than hiding its original livery.

The T120 build, workshop view

FCR Original has been building Triumph Modern Classic bikes since 2012. We don't sell universal parts: every FCR Accessoires accessory comes from a real build, fitted and tested in the workshop before going on sale. This hands-on experience guides our recommendations throughout this guide.

On a T120, our build logic almost always follows the same order: first the visible and functional (lighting, rear), then sound, then comfort and handling, and finally the detail solutions. This sequence gives a coherent bike at every stage, without ever breaking the model's aesthetic balance.

Our T120 build as an example

To illustrate, here is a T120 built in our workshop. A premium heritage base, turned into an elegant neo-retro roadster, entirely with plug and play FCR Accessoires parts. Here are the accessories fitted to it, all clickable:

The accessories catalogue by category

Here is the full range of FCR Accessoires parts for the Triumph T120, sorted by use. All are plug and play unless stated otherwise, and compatible with the T120, T120 Black and T120 Elvis Edition versions.

Exhaust and engine

The Triumph Modern Classics exhaust system is one of the most striking transformations: it brings a street bobber look and a deeper sound, in stainless steel, available in brushed or black finish. On the intake side, the K&N air filter improves airflow. To protect and dress the lower engine, the sump guard and its v2 version reinforced add real character, completed by the machined engine cover kit.

Cockpit and styling

To redraw the cockpit, the Black Bobber handlebar and the Alienor chrome handlebar radically change the riding position. The relocated ignition bracket cleans up the cockpit. On the tank, three machined caps to choose from: Le Monza, Le Billet et Le Rippled. For mirrors, the range covers every style: Highsider Montana, Classic Kit, Sport Kit and the Rizoma One, Eccentrico et Spirit.

Seat

The Triumph Modern Classic seat is handcrafted in France in partnership with NPS Sellerie, a French master saddler. Several colours are available (tobacco, black, wine, smoke, cognac), for comfort and a style true to the Bonneville spirit. To find out more, see our article on the creation of an FCR Original x NPS Sellerie seat.

Lighting and signalling

On a T120, replacing the bulky stock turn signals is often the first step. The Mini Bates front and rear turn signals et les FCR Original front turn signals are CE-approved. At the rear, the Triumph 3-in-1 turn signals et les 3 en 1 FCR Original combine turn signal, position light and brake light. The Bates LED tail light, the phare rond Vintage Bates, the Bates headlight grille and the complete headlight kit complete the set.

Bodywork and plate holders

To clean up the line, the front fender, the rear fender, the complete fender kit and the rear fender kit reshape the volumes. For the plate, the side plate holder and the universal holder free up the rear wheel, while the side number plates add a racing spirit.

Protection

Often overlooked but essential over time: the chain guard, the Off-Road radiator guard, its Shield and the JMP tank protector. For security, the disc lock holder with SRA lock fits cleanly.

Braking and brake lines

To improve braking and looks, the front Aluminium Nitro 310 mm and rear Aluminium Nitro discs lighten and modernise. The Banjo 90° brake line aircraft-grade optimises lever feel.

Suspension and handling

This is one of the most rewarding areas on a T120. The Shock Factory 2Win shocks transform behaviour on rough roads, and the Hyperpro fork kit completes the front. The wide fork yoke kit opens the way to more radical builds. For a premium finish, the Kineo spoked wheels elevate the T120.

Riding position and comfort

Les Triumph Modern Classic footpegs et les rear footpegs, CNC-machined, add finish and grip. For navigation, the GPS Beeline Moto II blends discreetly into the cockpit.

Drivetrain and maintenance

Le Triumph Bonneville T120 belt drive kit lets you switch to belt drive, specific to the T120. For routine maintenance, the K&N air filter maintenance kit, the BS15 smart battery charger, the Power Box PB-02 battery booster and the Venhill clutch cable cover the essentials.

Exhaust: which finish to choose

The exhaust system is the most requested part on the T120. It is made of stainless steel, available in two finishes. Here is how to choose depending on your project.

To go further on choice and maintenance, see our dedicated guides: the best Triumph Bonneville exhaust upgrades, the complete exhaust choice guide et exhaust system maintenance.

Where to start your build

Before the catalogue, the question always comes up: which accessory to fit first? Here is the order we recommend in the workshop, from the most impactful to the finest.

For those who want it all at once, the Triumph essentials kit brings together radiator guard, sump guard and chain guard in a coherent set. If you are just starting, our complete Triumph Bobber guide and the roadworthiness test guide usefully complete this read.
