Henry actually gave the American debut of the YZM at Gatorback Cycle Park in Gainesville, Florida, in 1998 for the opening round of the AMA Motocross Championship. He got great starts in both motos and finished eighth overall.

In 2004 only one 125cc rider - Bubba Stewart.
By 2005, there were no 125's... in the 125 class.

Bubba Stewart raced a 2-stroke until start of 06.

Tim Ferry was one of the first to make the switch to four-strokes in 2000 riding the Yamaha YZ426F, but only in outdoors. It wasn't until five years later that he would make the switch from two-stroke to four-stoke in Supercross. The sheer power of the four-stroke did great in out-powering the 250 two-stokes outdoors, but the bike was heavy and hard to maneuver indoors.

In 2001, the first rider to win a National on Yamaha's new thumper was not a high-paid factory super star, it was actually journeyman racer Larry Ward. Ward would take the victory at the Red Bud event, while riding for the Moto XXX privateer team.
