A dupla Osvaldo Coutinho e Alexandre Santos já não precisam de ser apresentados, nem a marca que os identifica – it roCkS!bikes. Num tempo muito curto, encurtado pelo talento e capacidade de trabalho, ascenderam à galeria das casas mais prestigiadas na preparação e construção de motos. Mas as motos que fazem merecem sempre ser apresentadas e nós merecemos conhecê-las. É certo que já foi exposta em imensos websites internacionais, mas a moto é portuguesa, os construtores também, este foi o seu berço e o seu lugar natural, e é também por isso que não precisamos de ter pressa em dar a conhecer os trabalhos que mais gostamos. Sobretudo porque já os conhecíamos e vimos ao vivo, em estreia mundial durante o Art&Moto 2014.

Sobre uma base Yamaha XJR 1300SP foi delineada uma aparência que combina de forma muito feliz a vertente desportiva com uma elegância sofisticada. O equipamento incorporado, muito dele construído pela própria it roCkS!bikes, visou melhorar significativamente a performance e conferiu um carácter único e exclusivo à moto.

Podemos dar a palavra ao Osvaldo e ao Alexandre que têm seguidores um pouco por todo o mundo e se expressam bem em inglês. E vale bem a pena percebermos a incorporação de trabalho e criação de que a moto beneficiou:

The bike was bought by its owner and it was in excellent mechanical conditions. We heard the ideas that the owner had for his bike, like the rear end and the name “Stealth”, because he is somehow related to the airplanes! Starting from there, we just get our hands at work to finish the bike just in time to show in Lisboa Art&Moto 2014, last April 26.

All the parts of the bike were disassembled and from the original bike we kept the gas tank, engine, part of the frame, swingarm, rear shocks, wheels and brakes.

In the front, we fitted an Kawasaki ZXR up-side-down fork and Brembo brake calipers. To fit all together we had to fabricate aluminum CNC 3D adapters for the calipers and axles for the wheels and steering column. On the rear, we refurbish the original Ohlins double shocks. The original tires were replaced by a set of Dunlop Sportmax, in stock sizes. 

The engine, which was in fair good condition, was painted in matte black and all the bolts were replaced. 

The original air box was removed and we designed our own set of velocity stacks with filter, custom built by us especially for this project, in CNC 3D aluminum plates. To protect the air filters from direct water and dust, we fabricated a fender for the rear wheel. 

The exhaust is a 4-2-1 titanium piece, with thermal wraps in the headers. Since the air flow was fairly improved, the carbs were re-jetted and properly tuned. The oil cooler is a very small high performance part and it was fitted with new oil lines. 

The lithium battery was displaced to the rear end of the bike and it fits a charger. The braking system was improved with new brake lines and Brembo calipers. We used a digital dashboard from “Motogadget motoscope pro”, with several information like revcounter, speedo, 0-100km/h acceleration, g-meter. This unit was mounted in one aluminum bracket designed by us and cuted into CNC. 

The aluminum footpegs are custom made by us. The license plate and turning lights are “Rizoma”, and the controls are “Motogadget” m-Switch. Since we had to keep the stock gas tank in this bike, we fabricated the seat and the metal rear section with a shape that follows the tank lines. The front and rear fender are custom fabricated aluminum parts. The seat is an exclusive handmade light brown leather piece. 

All the paint job and color schemes (black and gold) were done with airbrush and then spayed with a thin layer of matte varnish. The license plate was mounted in a bracket with the tail lights, which are just 2 single Leds. On the front we fitted a small headlight, painted on the dominant color of the bike. Also the mount was custom made.
