For 2012, Mike will be riding a more or less stock GT Speed Series XXL. While GT has stepped up their game in the after market parts race, they are also bridging the gap between a low end and custom bikes by offering their top parts package, which included a new 2012 cassette hub, chromoly forks and chromoly bars). Day plans to make his run for the 2012 Olympic team on an XXXL version of the bike. Between the size of some of the current Supercross tracks and Mike's height of 6' 3", the longer bike will help him adapt a bit easier to the tracks and handle a bit better.
