California teenager Michael Leib is one of two Americans on the FIM World Championship circuit this year, which starts this weekend in Sevlievo, Bulgaria. Leib is riding a factory Husqvarna in the same MX2 class as Cosworth Yamaha's Zach Osborne, who hails from Virginia. Leib has been dealing with an injury the last couple of weeks, as he explained in this well-written blog from Europe.
