Arlan Lehman began tuning and servicing motorcycles in the late 1970s. After working in the service department at a local Yamaha dealership he decided to branch out on his own. LRD (Lehman Research and Development) began in 1982 in a 96 square foot workshop in Amity, Oregon. After 26 years of building LRD, Arlan decided to spin off the service business and create LED (Lehman Engine Dynamics) Performance.

Throughout the 80s, 90s, and into the new millenium, Arlan’s engine and exhaust designs have won over 40 National Championships. He has built engines for some of the best riders in the world including; Gary Denton, Barry Hawk, Bill Ballance, Jeremiah Jones, Team NACs and many others. The feedback that he received from these experienced riders helped him perfect a winning formula for building the very best exhausts and engine packages on the market. Gary helped Arlan realize that he must design products with acceleration and a broad, usable power band in mind. This design principle helped Arlan continue the winning streak with 11 Cross Country Championships, as well as Pro MX National Championships, Open Pro-Am Championships and A & B class National Championships.

Arlan originally founded LRD Performance in 1982 in a small shed outside of Amity Oregon. Over the years he taught himself the secrets to high performance. He sold LRD in 2002 and worked there until 2008. He then bought back some of the original tools and equipment and moved his shop to Gresham and started LED Performance where he continues to find better ways to make things go way too fast. In his down time Arlan enjoys riding dirt bikes. He also loves vintage dirt bikes, especially ‘70s YZs and RMs.
