We’d spent months building up both rigs for the trip. Our ancient HD8 got a raft of ThumperFab parts that we put to the test last year, as well as 32-inch tires and KMC wheels. Hoyer, meanwhile, threw the SuperATV book at his HD10, bolting on doors, a windshield, front and rear bumpers, and a BFT suspension kit that allowed him to run a set of 32-inch Kenda tires. The real trick kit was a modified Maverick X3 clutch from KWI. The two rigs ate up everything we threw at them until a navigational miscalculation put us on a black diamond route and gravity took over.
