The Spanish duo of José Luis Cardoso and Carlos Cardús are the latest names to be announced for the inaugural World GP Bike Legends event at Jerez.
The 250cc legends join the likes of Freddie Spencer, Wayne Gardner and Kevin Schwantz at the special event, which takes place on 19-21 June.
Cardoso, who won the Spanish 250cc title back in 1982, will take part in the 250cc Race of Legends, with Cardús competing in the 500cc Legends race.
The Seville-born Cardoso competed at both national and international levels and won the 1998 Spanish 250cc Championship, whilst finishing in 11th place in the 250cc World Championship in the same year. His performances that season led to him moving up into the 500cc Championship in 1999 with the TSR Honda Team.
Cardús, who was also known by his nickname of Tiriti, raced in the 250cc World Championship for over a decade after his Spanish win in 1982. He would finish on the podium 26 times during that period, winning five races and finishing as the runner-up to John Kocinskis in 1990.
Cardús would have been crowned champion that year had it not been for a mechanical-failure in the final race of the season.
The special World GP Bike Legends weekend will have 125cc, 250cc and 500cc action, with a full practice, qualifying and race sessions taking place across the three days.
Alongside all of the action on the track, there will also be live music from Bonnie Tyler and former World Superbike Champion, James Toseland.
Until 31 March fans can get their hands on early-bird weekend tickets for €55 and with an open paddock policy, they will be able to get up close and personal with the GP legends taking part.
