In the world of dirt bike racing, Ryan Dungey needs no introduction. Behind the most dominant rider of the current era is a crew of hard-working KTM team members, along with his right-hand man/ace mechanic, Carlos Rivera, who is responsible for keeping the number-five KTM 450 SX-F purring like a kitten. Hailing from Puerto Rico, Carlos has always been passionate about racing motocross and working on his own bikes. At age 20, he and his new wife, Thelma, took the plunge and moved to Florida so Carlos could attend MMI and pursue a career as a professional mechanic. While in Florida, he met Cole Gress, who ran Suzuki’s amateur program, and he introduced Carlos to an 11-year-old ripper named Davi Millsaps, who was in need of a race mechanic. A bond was formed, and Carlos split time between working at a Suzuki dealership and turning wrenches for Davi. When Millsaps signed his factory Suzuki contract and brought Carlos along, it was a dream realized for both parties. Winning the 2006 AMA Supercross 250SX East Championship together, Carlos and Davi saw great success and worked together until parting ways when Davi went to JGR Yamaha.
