Moving up from the Lites class to the full time 17 rounds in the premier 450 Supercross class is a big step for any racer. Making it a double whammy, Kyle Regal is also going from Privateer Status to a full Factory Sam Manuel L & M Yamaha ride.
Kyle rode a few 450 Supercross rounds last season, when he wasn?t racing in the Supercross East Coast Lites, but it was this summer Kyle really gained momentum on the 450, finishing ninth in the series final standings.

Monster Energy Yamaha?s Zach Osborne stands on the edge. The American is the sole waver of the Stars and Stripes in the FIM Motocross World Championship and after nearly four years as part of the Grand Prix circus the 22 year old is staring at his last possible chance to lay his hands on an MX2-GP world title. The fact that the Virginian has factory status as part of Yamaha?s six-rider-strong assault on both FIM Motocross World Championship categories in 2012 is further indication that Osborne is on the threshold of something very promising indeed. Two podiums from four appearances in the AMA West Coast Lites Supercross series this January adds to the sense of expectation for the coming months where he is likely to go head-to-head with names such as Herlings, Searle, Van Horebeek and team-mate Arnaud Tonus for the crown.
Thrown in at the deep-end mid-GP season during 2008 for the Utag Yamaha crew (now the Dixon splinter of the Monster Energy Yamaha set-up), foiled by injury in 2009 and partially in 2011, Osborne still managed to pack-in a comprehensive British Championship title in 2010, GP podium results for the last two campaigns and the prestigious Marty Moates Cup at Glen Helen for his home event in 2010 for best performing American. His victory at the Grand Prix of Turkey in 2009 is still a career highlight.
