Roczen has already undergone surgery on the fractured arm and will now focus on his recovery. The rider plans to be back on the track in time for late February and the start of the Supercross Lites competition.
"With the full support of the Red Bull/KTM Factory Team, Roczen is expected to make a full and speedy recovery in time for the commencement of the 2012 Supercross Lites East Championship Series," the team said in a press release.
The 17-year-old rider from Germany had a strong season last year in the FIM Motocross MX2 competition, where he won 19 races en route to the championship. The victory gave KTM their fourth-consecutive title in the series, after Tyla Rattray won in 2008 and Marvin Musquin won in 2009 and 2010. Roczen placed second in the 2010 competition as well.
After signing with KTM last year, Roczen was only able to race a few Supercross Lites races, so this will be his first full season in the competition.
