Poor weather may have delayed the start of MotoGP testing activities at Aragon on Tuesday, but Repsol Honda were able to unveil this prototype version of the 2014 RC213V.
HRC used a similar tactic to great effect last season - the 2013 bike making its debut in July's Mugello test, then being raced by eventual title runner-up Dani Pedrosa from the following Laguna Seca round.
This time around Pedrosa is already leading the championship, by seven points from Yamaha's Jorge Lorenzo, with rookie team-mate Marc Marquez in third.
Yamaha, Suzuki and the satellite Honda teams, which tested at Catalunya on Monday, are also due to join Repsol Honda at Aragon.
The 2014 MotoGP regulations for official manufacturer entries require one less litre of fuel per race, down from 21 to 20 litres, and use of the control ECU hardware but freedom to continue developing their own software.Don't miss out!
