Ultra Thin UV Protective Clear Coat:

The carbon fiber weave is protected from radiation with thin layer of special clear UV protective coating. The rim surface is very clean, smooth and UV resistant and ensures your wheels have zero notch effect on the surface.

Optional Translucent Colors:

Connect the power of color for a personalized look.

Rotobox’s unique line of Translucent Colors are made exclusively for carbon fiber composite use. It is a chip resistant, UV stable and highly consistent protective coating in both color and finish. Our special color formulas are designed to evoke emotion and capture attention, we also have the ability to custom paint your wheels with your favorite color, match a manufacturers color and even add graphics that display though the clearcoat. Talk with a customer service representative about additional customization options.

High Accuracy of Center Parts:

The center parts of the wheel include aluminum alloy 7075-T6 hubs, spacers and sprocket carrier. All parts are CNC machined at accuracy of ±0.02 mm for each bike model specifically and designed to be direct replacement for stock wheels, except for sprocket.

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 red.

Venting Hole:

Each rim spoke has special venting hole placed on the bottom of the spoke to prevent condensation.

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.

A Rib For Torque Resistance:

Each spoke of the wheel has a special rib to improve torque resistance.

Rotational Aerodynamics:

Eliptical cross-section of spokes for lower aerodynamic coefficient during rotation.

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.

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.
