American riders Blake Young and James Rispoli tested at Indianapolis on Friday as the young duo prepare for their respective MotoGP and Moto2 wild-card rides next weekend.
Double AMA Superbike runner-up Young (25) will compete for Californian team Attack Performance in his third wild-card outing of the season on the APR Kawasaki in the CRT MotoGP class.
He finished 21st at the Texas MotoGP in April on his debut in the series but was ruled out of last month's round at Laguna Seca after a spill in practice destroyed the APR machine.
“It's pretty exciting to be home here in America and be able to ride on the world level like this, and being able to do it at the Indianapolis Motor Speedway makes it all the better,” Young said.
“My crew has done an amazing job of working together to rebuild the bike [following the Laguna Seca crash] and put me on a world stage here.
“I'm a young rider trying to come up and make a name for myself, so being able to ride around here and put up a good result will definitely give me a chance to showcase my talents.”
Meanwhile, Rispoli – a two-time AMA Supersport champion – will make his Moto2 debut for Michigan-based GPTech, using a Tech 3 chassis.
The team has contested the Moto2 race at Indy twice before in 2010 and 2011, finishing ninth with Jason di Salvo and 31st with Jacob Gagne.
Last year, GPTech competed in the MotoGP race at Indy, taking 16th with Aaron Yates.
Rispoli said: “This is my first time here, first time taking a look at the track in getting ready for the MotoGP weekend.
“The first couple laps were just eye-opening as I was just trying to take in the view, where I'm at and what I'm doing, before you get into the focus of racing.
“I definitely tried to absorb as much as I could before we got to work,” added the 22-year-old.
“I don't really know what to expect with the first time racing at the highest level of our sport, and I thank everyone at GPTech for getting me in front and showcasing my talent.”
