REC MX LLC was established in 2004 as a design and consulting company, designing motocross and ATV components for many other manufacturers. We’ve designed numerous parts for motocross bikes and ATVs, including aftermarket billet aluminum big-bore cylinders, custom forged pistons, exhaust components, suspension components, engine covers, carburetor parts, bike controls, carbon fiber parts, and plastics.  Our founder is not just a motocross racer, but also a mechanical design engineer with over 20 years professional experience.  He has designed parts not just for Motocross and Supercross but also MotoAmerica, Le Mans, NASCAR, Trophy Trucks, Monster Trucks, Drag Racing, and worked with OEM’s like Yamaha, Toyota, and Tesla.  Throughout the years we’ve made parts for our own bikes, and found we could improve on some existing parts. When people started asking where to buy our one-off parts, we decided we should ramp-up production and make them available to the public. Each component is design engineered in a 3D CAD system and when required tested in computer simulated FEA (Finite Element Analysis) software, before prototypes are ever made. We then thoroughly test all parts with top professional riders from around the world. Before parts are sold to the public, each part is dimensionally and visually inspected for quality. All REC MX parts are made in the USA and then race tested worldwide. We already have national distribution and we are actively pursuing additional channels to sell REC MX parts.

If you need something custom, REC MX offers design and consultant services specializing in 4-stroke MX and ATV components. We offer 3D CAD design, assemblies, FEA analysis, engineering prints, and rapid prototyping. Please contact us for more info.

REC MX Billet Engine Components have been used and race tested in the AMA Supercross, AMA Arenacross, and AMA Motocross National series, FIM GP’s, Australian Supercross and Motocross, French Supercross and Nationals, Supermoto, Enduro, and Cross Country races by professional riders and race teams like:
