The Rotobox Carbon Fiber Wheels are ultra light motorcycle wheels for racing and road application and an upgrade product to any model of sportbike. Our wheels have been designed to meet the highest level of racing performance and due to one-piece hollow carbon cast construction the wheels develop a safe and controlled advantage in speed, providing the lowest moment of inertia and the lowest gyroscopic effect.

The Rotobox wheels are the lightest and the strongest carbon fiber motorcycle wheels, due to use of premium materials and advanced technology. Our process of producing one-piece hollow carbon cast is an adaptation of high-pressure Resin Transfer Molding technology to ensure the best quality, the continuity of the procedure and subsequent safety of our products.


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.


Since the very first day Rotobox strives to take the performance of carbon fiber wheels to a new level. By continuously pushing the boundaries of creative engineering our products set industry standards for lightness, stiffness, design and premium quality. Whether on the track or on the road - the racing DNA of the Rotobox team is not only reflected in our wheels, but can be felt with every meter driven. The feedback of our great costumers confirms, that we are turning the wheel the right way.


The wheels conform to safety standard JASO T203-85 for JWL dotE Certification. The construction of one-piece hollow carbon cast of the Rotobox wheel develop the safest and most controlled advantage in speed. Rotobox wheels are truly the first safe carbon wheels for motorbikes on the market.


The Rotobox wheel gives great response, because of faster acceleration and better braking. This is a great advantage in turns allowing higher speed entering into the turn and faster accelerating after the turn. Rotobox wheels give your bike clever performance.


The Rotobox wheel has greater stiffness, because of the construction of one-piece hollow carbon cast. The wheel is produced with high-pressure RTM technology, which ensures a clean, smooth and hard surface.


In seven years of intensive R&D work we have made the most powerful wheel for road and racing motorcycles. We are focused on sportbikes, because when the bike uses Rotobox wheels it becomes at least 5 kg (11 lb.) lighter than stock and that is a huge amount of unsprung mass shaved from the bike; it is basically like adding some HP to the engine.


All Rotobox wheels come with a two-year, limited manufacturer's warranty.


The Rotobox wheels correspond to the safety standard JASO T203-85 for JWL dotE, which requires testing at four different fatigues. Because safety is our top priority, we set up an in-house test laboratory to constantly check and improve the quality of our products:

  • Radial Fatigue Test: The test aims to confirm the durability of the rims and hubs. For this purpose a drum is rotating the wheel at a constant velocity of 32 km/h while applying the radial load (FW: 3400N / RW: 5600N at min. 500.000 turns).

  • Torsional Fatigue Test: The test aims to confirm the durability of the spokes and hubs. For this purpose the wheel is fixed onto the support, while the torsional moment (FW: 500Nm / RW: 810Nm at min. 100.000 turns) is repeatedly applied through the contact surface of the hub.

  • Impact Test: The test aims to confirm the air retainability of the tires and strength of the rims, spokes and hubs. For this purpose the striker weight (FW: 225kg / RW: 410kg) is dropped on the wheel from a height of 150 mm to apply the impact load.

  • Cornering Fatigue Test: The test aims to confirm the durability of rims and hubs. For this purpose the wheel is fixed to a rotary disc, that is able to provide a bending moment (FW: 2500Nm / RW: 410Nm at min. 100.000 turns) to the center of the wheel, while rotating with a constant velocity.

Thinner Spokes:

The new elegant spoke design brings aerodynamic and weight improvements. Although the spokes are thinner the BOOST is stronger than ever - with a permissible maximal static load of 280 kg on rear and 180 kg on front wheel.

High Pressure Core:

The new technology achieves a high density of armature in the composite extreme metric accuracy and a greater smoothness of the wheel surface. In addition - the wheel becomes watertight.

One-Piece Hollow Carbon Cast:

The shape, structure and dimensions of each wheel are defined by highly precise aluminium tools CNC made inhouse specifically for a wheel design. Our process of producing one-piece hollow carbon cast is special high pressure Resin Transfer Molding technology to ensure the best quality, the continuity of the procedure and subsequent safety of our products.


Produced using Rotobox's unique 3 component composite - combining carbon, epoxy and stainless steel. The stainless 2.5mm steel wire is integrated in each side of the rim increasing its impact resistance at the most critical outer part.

Structural Rib:

Thanks to the High Pressure Core Technology the structural rib is placed in the inner side between the spokes, with its mission to support the stress hot spot of the wheel. As a result the BOOST elegant spoke design brings greater stiffness and although the spokes are thinner the BOOST is stronger than ever.

High Quality Center Parts:

For each motorcycle model the hubs are CNC machined from high quality 7075 T6 aluminum alloy used in the aviation industry, anodized into optional color and permanently assembled to the carbon rim.

Ultra Thin UV Protective Clear Coat:

The carbon cast is protected from radiation with a very thin layer of special clear UV protective coating. Together with the clear and smooth rim surface it ensures the wheel a zero notch effect.

Anodized 90° Angled Valve Stem:

We use 90° angled valve stem to ensure air pressure resistance at high speed. Default color of valve stem is silver.

The Lowest Unsprung Weight:

Unique design of the wheel yields the maximum output for each specific motorcycle model while significantly reducing overall weight for top performance.

Rim Reinforced With Stainless 2.5mm Steel Wire:

For greater impact resistance of the rim we insert stainless 2.5mm steel wire inside each side of the rim.

Anti-Slip Adhesion Rim To Tire:

We apply special anti-slip compound on adhesion rim-tire area to prevent rotation of the tire during acceleration and breaking.
