The Yamaha XJR 1300 CS-06 Dissident turns a familiar air-cooled muscle-bike silhouette into a sharply tailored café racer. Built by Portuguese workshop it roCkS!bikes for Yamaha’s XJR 20th-anniversary Yard Built program, it is defined by one continuous body section, a compact cockpit and a deliberately period-minded paint scheme.

One-piece bodywork sets the proportion

The most distinctive feature is the hand-shaped monocoque that runs from behind the triple clamps to the tail. Rather than treating the tank, seat base and rear cowl as separate pieces, it roCkS!bikes gives the Dissident a single flowing profile. The result is a low, uninterrupted line from the small front fairing across the gold tank and into the raised tail.

That shape is especially effective from the side. The narrow seat, black insert and lifted rear section keep the visual weight above the back wheel, while the white lower bodywork prevents the long tank from appearing too bulky. A compact fairing with a recessed amber headlamp gives the front end a distinct identity without hiding the XJR’s large engine.

Classic Yamaha graphics, modern chassis hardware

The pearl white, black and gold finish references Yamaha’s familiar speed-block-era colours while keeping the custom work visually coherent. The anniversary side panels add a graphic focal point, and the gold details carry through to the rear shock reservoirs, chain and exhaust headers.

According to the supplied build information, the suspension and braking equipment were substantially revised. The front end uses upside-down forks from a Yamaha YZF-R1, while ISR hardware includes six-piston front calipers, twin 340mm discs, a 267mm rear disc and matching front-brake and clutch master cylinders. LSL clip-ons and rearsets reinforce the café-racer riding position suggested by the bodywork.

The XJR engine remains on display

it roCkS!bikes leaves the broad four-cylinder engine exposed beneath the monocoque. Lightweight aluminium engine covers with viewing windows are listed among the changes, adding a mechanical detail to an otherwise very smooth design. A handmade four-into-two stainless-steel exhaust runs low along the right side before ending in a large, plainly visible outlet.

The build also includes a small oil cooler, a digital Motogadget Motoscope Pro dashboard and an aluminium Monza-style fuel cap. Seventeen-inch tubeless Kineo spoke wheels, fitted with Pirelli Angel GT tyres according to the supplied specification, balance the traditional spoke appearance with contemporary wheel construction.

A focused anniversary interpretation

The CS-06 Dissident succeeds because its modifications work as one design rather than as a collection of accessories. The single body shell establishes the motorcycle’s proportions, while the fairing, clip-ons, exposed engine and gold detailing give the XJR a purposeful café-racer character. It remains recognisably Yamaha, but the Portuguese builders’ restrained surfacing makes this anniversary tribute markedly more individual.

Yamaha’s XJR 20th Anniversary party continues with the Portuguese custom builders’ it roCks!bikes Yard Built CS-06 Dissident café racer. “it roCkS!bikes were high on the list of builders we wanted to work with to celebrate the 20th anniversary of the XJR. Their unique signature style one-piece monocoque is super clean and they have shown they can build stunning custom machines without losing the heart of the original, keeping the essence of the great chassis and raw engine power. With the CS-06 Dissident, it roCkS!bikes have again built a beautiful bike,” says Shun Miyazawa, Product Manager – Yam Working in a small workshop just outside Porto, in Portugal, Osvaldo Coutinho and Alexandre Santos are civil engineers by day and it roCkS!bikes craftsmen by night. Their engineering skills are plain to see in the bikes they build, and in their signature monocoque one-piece fuel tank, seat and tail units that they use for all their bikes.
