MDK Speed Equipment welcomes you. 30 years of experience in Aerospace Engineering and our passion for high performance motocross bikes means that you have access to technology and products not usually made available to the public.

Everything we do here is about making your 4-stroke motocross bike perform like a works bike. Countless hours of dyno, flow bench, and track testing allow us to provide you with products and services that deliver great performance and durability.

Team riders Nick Wey, Martin Davalos, Justin Brayton, Billy Laninovich, Matt Goerke,and Ryan Sipes use MDK prepared motors to get a performance advantage they can’t get anywhere else. The time we spend working with top riders like these means that when you get an MDK performance product or service, you know that it’s been successfully proven in the most demanding conditions.

Our AS 9003 aerospace manufacturing protocols are used every time we build a motor or suspension package for you. Every component is tested and scrutinized, so you can be assured that you will get the highest quality product available for your motocross bike.
