Marc Marquez and Dani Pedrosa rode some promotional laps of the Red Bull Ring in Austria on Tuesday, using an RC213V-S road bike.
The 188,000 Euro machine is based on the RC213V prototype raced by the Repsol Honda riders in MotoGP.
Austria last held a motorcycle grand prix in 1997, before Red Bull took over what was then named the A1 Ring. It is returning to the calendar from August 12-14.
2016 championship leader Marquez first sampled the circuit last year during another promotional event, using an RC213V, although the asphalt has since been changed.
