Red Bull/KTM's Ken Roczen suffered a broken left arm in a practice crash while riding at the KTM test track in Corona, California, on Monday, December 26. The German will now concentrate his efforts on his recovery and won't make his 2012 debut until the Supercross Lites East Championship series that begins on February 25 n the Georgia Dome in Atlanta, Georgia.
Marvin Musquin will go it alone for the Red Bull KTM team in the Supercross Lites West Series.
"Broke my arm today," the German MX2 World Champion said on his Twitter page. "Got surgery right away and we're expecting to ride east coast! Good thing is... hopefully, [there's a] KTM champion in west and east."
