1993 500cc world champion Kevin Schwantz rode his first laps on Suzuki's MotoGP machine at the Circuit of the Americas on Tuesday.

Suzuki is holding a private two-day test to continue preparations for its 2015 MotoGP comeback, while 49-year-old Schwantz is present to ride a Yoshimura Suzuki Superbike ahead of his participation in this year's Suzuka 8 Hours.

But the opportunity for the former Suzuki grand prix star to try the new 'XRH-1' inline four-cylinder was too good to resist.

According to RoadRacingWorld.com Schwantz set a best lap time of 2m 12.7s. The fastest MotoGP race lap was a 2m 3.5s (Marquez) and the slowest a 2m 8.6s (Parkes).

Schwantz may get some further MotoGP laps on Wednesday's second and final day of testing, alongside Suzuki's full time development riders Randy de Puniet and Nobuatsu Aoki.

Having settled his legal differences with COTA, Schwantz is now an ambassador for the circuit, which hosted round two of this year's MotoGP championship on Sunday.

Suzuki is expected to make a wild-card entry in the season-ending Valencia round, while Crescent Suzuki WSBK star Eugene Laverty will get his chance to try the MotoGP bike soon.
