I cant say enough about Mark as he has so much patience and passion for his craft . We spoke for 45 minutes long after his listed hours were closed . He carefully explained so many intricate details and why they are so important for my application. It was an absolute honor 🎖 that he would take the time . I boxed up my transmission and sent it that very moment with great confidence.

I have gotten several transmissions done through him, he is a pleasure to deal with and his product is flawless from intake to shipping back. We use in our M8 Harley Drag bike and has gone through three seasons of abuse and still operating smoothly

I needed my transmission gearset replaced on my 2014 limited. Thomas, at the Fab Shop here in Santa Fe suggested putting in a 2017 gearset out of a M8 that was rebuilt by R&D. I gave the ok and man, sure glad I did. He was right. This gearset from R&D is simply the best transmission I have ever had in my bike. Smooth, quit, shifts quickly and no rattle in first gear. Like Thomas said " you can't go wrong ". He was right !
