More than thirty years of development with cold cast metallic materials, John and Donna have developed a world wide market for V-Twin aftermarket motorcycle emblems for Riders, Bike Builders, Clubs, and Manufacturers wanting to personalize their bikes.

In addition to making aftermarket motorcycle emblems for individual riders, we can create a 3D emblem of most any club logo and Zambini Bros will donate a percentage of sales back to each chapter that locks in the minimum quantity.  Give us a call to discuss turning your Club Logo into a 3D piece of art.


Our Motorcycle Emblems are not solid metal. There are several reasons for this. They would be much more difficult to mount and would tarnish much faster. 

All Zambini Bros Motorcycle Emblems are cast using a multi part process. Starting with 90% or better, true metallics of Bronze (Gold), Aluminum (silver), and Copper mixed in a thermoplastic matrix. We then buff and hand polish each piece bringing the metal forward allowing the definition to show.  We also use Genuine Turquoise powder where applicable.

We also offer Custom Colors and can create almost any color to match your bike.

The finished product is an easy to mount, lightweight, true metallic, 3-D motorcycle emblem that can be gently heated before mounting (if needed) with a blow dryer or heat gun and pressed in place, using a bead of silicone sealer on the backside outer edge, for a perfect fit. This is something that could not be accomplished with a solid metal emblem. 

As we all know, the elements of moisture, air, and sun can tarnish and fade the metallic veneer. To keep your Zambini Bros Motorcycle Emblem long lasting, simply remove it, or isolate it to protect the surface it is mounted on and recondition with a fine grit steel wool. Then buff and hand polish to its original luster. We like to use Pro Black Beauty Brightener and Sealer but any similar polish will work. Simply brush a thin coating over the entire emblem, allow to dry and wipe off with a soft cloth. Lastly, you may also apply a coat of Clear Gloss UV Protectant spray paint if desired. 

Brand your Bike with our affordable, easy to work with, 3-D motorcycle emblems that will last for years to come.
