Billy Wight Luxon MX was founded by Billy Wight in 2014. An avid motocross rider, mechanical engineer, and the founder of Luxon Engineering in 2007, Billy saw opportunity in the motocross industry. The aftermarket motocross industry typically employs basic engineering techniques to the design of their product. Often times aftermarket companies "wing-it" or simply copy stock designs and machine them from billet. Billy’s experience owning a consulting engineering company range from the design of nickel-titanium spinal implants, to structural analysis of nuclear reactors, to the design of suspension components for LMP style road racing cars. This level of engineering requires the latest in technology and techniques, and it was apparent that this level of technology had yet to be applied to aftermarket motocross components.

Stock vs. Aftermarket

Many riders make the argument that stock is good enough, and for many riders that’s completely true. Riders who demand the absolute best though, must turn to aftermarket components. While the OEM manufacturers have huge budgets and vast design resources, they must also produce a bike affordable for the majority of riders. They aren’t interested in extracting the last 20% of performance out of each and every component, otherwise the bike’s retail price would be astronomical. For this reason, nearly every component design on the motorcycle leaves room for improvement. This is where the aftermarket industry comes in, but the problem is that the capabilities of most aftermarket companies are fairly limited. Take triple clamp design for example:

This image shows a stock Honda lower triple clamp on the left and a leading aftermarket supplier’s version on the right. See the similarities? The aftermarket component, aside from a few differences, is just a machined version of the stock cast component. Why? Because that’s what they know works; there’s no risk in machining the same design as little has changed from an engineering standpoint. They can offer a product with minimal design effort that they know will work. But will it work the best or even just better than stock? No.

The stock clamps are castings, and their design is heavily driven by that manufacturing process. In general, most stock (and aftermarket) clamps are flat across the top and cored out on the bottom leaving ribs which function structurally. Also though, the ribs aid in manufacturing by maintaining a consistent part thickness and directing the flow of molten metal through the casting tool. Machined part design is not limited by these manufacturing requirement. Luxon’s clamp design (shown below) takes advantage of this to offer a product with a substantial performance advantage, not just a machined version of the stock parts.

Advanced Engineering Technology

By employing the tools of Luxon Engineering, Luxon MX’s design, analysis, prototyping, testing, and manufacturing capabilities are unmatched in the aftermarket motocross industry. The annual cost of software, computers, tooling, and an engineering team to run it all is well beyond what most other companies can justify. But since Luxon Engineering already has these capabilities, Luxon MX is able to use them in creating the best aftermarket motocross components available.

Design and Analysis

Design and Analysis

The primary technology that sets us apart from our competition is our design and analysis tools. In particular, the application of a technology called Topology Optimization. In short, this process takes a volume of material “that can be there” and reveals the material “that needs to be there." The software uses advanced algorithms iterating though analysis runs to satisfy the optimization goal, which is typically to maximize stiffness for a given weight. The result is a truly optimized product - lighter, stiffer, and stronger than stock. More details about the application of this technology are available on our triple clamp page.



Our location in southern California is ideal for easy access to on-track testing and rider feedback. Beyond this, we utilize our engineering technology for sensors, data-logging, video overlay, and other advanced techniques. This data is then fed into the design process accurately representing loads, component deflections, and more; all to deliver a better product.

Prototyping and Manufacturing


With in-house CNC and other manufacturing capabilities, Luxon MX is able to quickly and effectively run through prototype iterations and transition to production manufacturing. Our advanced CNC machines and tooling leads to manufacturing quality levels typically only seen on works level factory components. Our products are manufactured in-house at our San Diego location to ensure the highest quality standards.
