We're excited to introduce Rotobox's new innovative Bullet Wheels. Known for their impeccable carbon fiber construction, ultra weight savings, and all-around performance improvements, Rotobox is setting the trend again with their new Bullet Wheels.
The Rotobox wheels are the lightest and the strongest carbon fiber motorcycle wheels, due to the use of premium materials and advanced technology. Their process of producing carbon cast is an adaptation of high-pressure Resin Transfer Molding technology to ensure the best quality, the continuity of the procedure, and the subsequent safety of their products.
ABOUT BULLET 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. Rotobox 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.
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.
THAT'S HOW ROTOBOX ROLLS: 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 their 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 their wheels, but can be felt with every meter driven. The feedback of costumers confirms, that they are turning the wheel the right way.
SAFETY FIRST: 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.
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 they have made the most powerful wheel for road and racing motorcycles. Rotobox is 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.
WARRANTY: All Rotobox wheels come with a two-year, limited manufacturer's warranty.
TESTING LABORATORY: The Rotobox wheels correspond to the safety standard JASO T203-85 for JWL dotE, which requires testing at four different fatigues. Because safety is their top priority, they set up an in-house test laboratory to constantly check and improve the quality of Rotobox 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 retain-ability 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.
Features:
- Three Component Composite (carbon-epoxy-steel) and it's unique one piece hollow carbon cast construction, Rotobox is redefining the quality and manufacturing standards in the industry.
- One Piece Hollow Carbon Cast: 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.
- Solid Thin Spokes: To create solid thin spokes we use special carbon fiber yarn developed for military use. Because of the extreme mechanical properties of the fibers that we use (tensile strength 6000 MPa) and high density forging process, the cross section of spokes becomes small and compact.
- Chopped Carbon Fibers Meet Woven Fabric: Rotobox's unique technology combines shopped carbon fibers with woven fabric seamlessly in one-piece monocoque.
- 7075 T6 Aluminum 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.
- High Pressure Core: This 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. 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 with a permissible static load of 280 kg on the rear and 180kg on the front wheel
- UV Protective Coating: 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.
- 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.
