ABOUT ROTOBOX CARBON FIBER WHEELS:
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.
THE MAN BEHIND THE PERFECT WHEEL:
Gregor Bizjak has worked as a research and development engineer since 1997 and is experienced with production management, CAD designing, CAM programming, reverse engineering and development of tools.
As a motorcycle racer, Gregor thought of the idea to develop and produce a carbon fiber wheel for motorcycles with a revolutionary design and technical perfection in order to achieve maximum racing performance. This design demanded that Gregor come up with an innovative way of producing a one-piece hollow carbon construction, something much more complex than what has been allowed previously. Gregor has truly reinvented the wheel.
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.
GO FOR BETTER RESPONSE:
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.
EMBRACE GREATER STIFFNESS:
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.
SPEED IS THE GOAL:
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 the most important feature the company has its own rigorous laboratory for testing:
- 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.
