Duncan Racing is the best in the industry! Our family has been going to Duncan Racing for 20+ years. They are the only company we will use. If you want it done RIGHT, this is where you go. Thank you for everything Duncan Family!

Duncan Racing is operated by two of the best in this industry. Loren and Lenny are above category their knowledge, experience and customer support. They do things the RIGHT way and they take care of their customers. I am beyond pleased with my interactions, service and quality of the products and workmanship that came from their shop. My bike screams. If only every business was this good, what a wonderful world it would be...

Great service, great parts and Leonard Duncan was very helpful.

Trust them with any repair they are amazing and honest.

Two generations of being life long professionals in machining, fabricating, building and repairing off road and race specific ATC, ATV and SxSs. Top notch services and parts provided world wide and supports many race series and riders across America and beyond. Pricing is fair and technical information provided is priceless; available online, by phone and in person. No one touches my motors, except Duncan Racing Intl!

These guys built a motor for me 5 years ago and it has been worth every cent. Bulletproof.
