Roger Lee Hayden, younger brother of 2006 MotoGP world champion Nicky, is to make his grand prix debut as a Moto2 wild-card at the Indianapolis round in late August.
Roger Lee is currently taking part in his first full World Superbike season with Pedercini Kawasaki, but has been signed to ride a Moriwaki chassis - the same design as leads the inaugural 2010 Moto2 title chase with Toni Elias.
"This is a great opportunity for me to race in front of my home crowd at a MotoGP event," said Hayden. "The Moto2 class is really competitive and I'm looking forward to jumping in the middle of it."
The entry is being backed by American Honda, with 1993 500cc world champion Kevin Schwantz to act as team manager.
"It's an honour for me to be chosen as team manager," said Schwantz. "We've been using CBR600RRs for some time now at our schools, and I've ridden a Moto2 bike and it's very good. I watched the first three Moto2 races and I expect the racing to be just as good at Indy."
The team will be staffed by technicians from Erion Racing technicians, American Honda's premier support team.
