N-Fab/AM Pro Yamaha’s Grant Baylor grabbed his first win of the season at the final round of the Kenda AMA National Enduro Series two weeks ago in Upland, Indiana. Grant’s factory mechanic, Cory McDonald, is one of the most knowledgeable mechanics in the pits, so we thought it would be the perfect time to do a Factory Bike Friday video with Cory and get an in-depth look at Grant’s bike from the guy who knows the most about it.
