Suzuki will get a status check in mid-June at Barcelona, as it plans to test its GSX-R 1000cc prototype against the three current MotoGP factory teams in preparation for a probable return to the premier class in 2014.

The test will be the first time Suzuki has been on track with Honda, Yamaha and Ducati since the season-ending Grand Prix in 2011 at Valencia. Suzuki withdrew from MotoGP after that season.

Suzuki test rider Nobuatsu Aoki visited the MotoGP test Tuesday at Sepang, observing the paddock and the company's future rivals.

"We are on schedule," Aoki said to British media. "We launched a new version of the bike last week, which performed pretty well. We're happy with the chassis and engine, but we still need to improve many small things."

Aoki said Suzuki has tested its GSX-R at Motegi and nearly weekly at the company's private test track. He said he will participate in the Barcelona test, along with a "European rider" he wouldn't disclose. Media speculation has pointed to current Aspar CRT rider Randy de Puniet as Suzuki's other test rider for 2013.

Suzuki will run a two-rider factory entry in 2014 on machinery with in-house electronics, Aoki confirmed. Dorna boss Carmelo Ezpeleta has said a grid spot will not be created for Suzuki and that the manufacturer must ally with an existing team.
