Donnie ended up racing Professional Motocross for 10 years in the top motocross races. Winning many titles along the way. He competed in the AMA National Hare and Hound Series from 1986 to 1993, and was named National 4 Stroke Champion one year as well as held the number 2 national plate for a year. After that he was a Test Rider for Cycle World Magazine for 16 years. It's safe to say that he has had a passion for motorcycles for most of his life and that has carried over into his current career, repairing and maintaining all different types of motorcycles and machines. Because of his knowledge and experience in this industry he holds himself to a higher standard and his integrity to his work is unparalleled.


From fixing a blown up motor on a vintage bike for a local rider, to prepping a bike for one of the top riders in the nation, he loves what he does. The challange to make any machine better, more powerful and smooth, is one he happily takes on. He is a rider, through and through.



Greg Kros started riding dirtbikes and snowmobiles at 8 years old, started working at G&L assembling new bikes at age 13 and started training to be a mechanic at age 14. Greg started work in Bountiful at Craigs Yamaha and went on to work for Honda Suzuki of Salt Lake for 15 years. He is considered one of the top mechanics in the state of Utah. He is certified in all brands, including Kawasaki, Polaris, Honda, Yamaha, Suzuki, and Arctic Cat to name a few. 


Gregs work ethic is one of the best in the industry. He can finish an amazing amount of machines in a week, let alone a day. Not only is he a fast worker but also has an incredible attention to detail and has rarely had anyone come back to the shop with an issue. Once your machine is fixed it usually stays that way! Greg takes great pride in his work and he knows you'll be satisfied with how your machine runs when he's finished with it.
