Bayside Performance recommends Drive Systems sprockets for all Rotobox applications but any sprocket that has the following measurements will work: 5 (10mm holes) with a PCD (Pitch Circle Diameter) of 100mm and a sprocket ID of 76mm.


Low weight, high stiffness, great strength and eye-catching design are the obvious reasons for the continuing growth of carbon fiber usage in the motorcycle industry. One of the most important parts to significantly improve a motorcycle’s overall performance – from handling, breaking to acceleration – are carbon fiber wheels. With the industries first 3 component composite (carbon-epoxy-steel) and its unique one-piece hollow carbon cast construction, Rotobox is redefining the quality and manufacturing standards of a whole industry. This puts us on the forefront of carbon fiber motorcycle wheel innovations.

Racetrack Inspired Design

The look of the Rotobox wheels is determined by the company’s philosophy to achieve the highest possible performance and safety with no compromises to popular design guidelines. To maximize the advantages of carbon fiber composite, and simultaneously reduce all known disadvantages, we let the experience and expertise of our professional testing team YART (Yamaha Austria Racing Team) flow into the wheel design. The outcome is a spoke, which meets the rim on a substantially large area.


One-Piece Hollow Carbon Cast: Rotobox is the first and still the only carbon fiber motorcycle wheel producer in the world to develop and use a unique 3 component composite - combining carbon, epoxy and steel. As the composite itself the one-piece hollow carbon cast production process is a novelty as well. During production several different types of CNC tailored carbon fabrics are hand placed into the negative forming mold of the high precision aluminum tool. For greater impact resistance a stainless 2,5 mm steel wire is added in each side of the rim. Next the liquid epoxy resin is injected into the sealed and tempered tool under very high pressure. This process of producing the one-piece hollow carbon cast is an adaptation of the special high pressure Resin Transfer Molding (RTM) technology. Ensuring the continuous quality, safety and accuracy of the production process.

Central Hubs

The hubs are CNC machined from 7075 T6 aluminum alloy, anodized into optional color and permanently assembled to the carbon rim. Designed specifically for each motorcycle model, the Rotobox wheels are a direct replacement of the OEM-wheels and are supplied with a cush drive, sprocket carrier, spacers and a choice of ceramic or steel bearings.

90-Degree Valve Stems

All Rotobox wheels come with 90-degree anodized aluminum valve stems that are not only easy to access, but keep centrifugal force from opening their Schrader valves and deflating tires during high-speed operation.

Racers Know, What Racers Need

How to make the lightest and strongest wheel on the world? That’s the question motorcycling racer, research & development engineer and Rotobox CEO Gregor Bizjak asked himself more than a decade ago. The answer was a revolutionary 3 component-carbon-epoxy-steel-composite and a newly developed production procedure, which paved the way for a new generation of high performance motorcycle wheels by Rotobox.
