Triumph's world Supers new team
McCoy had previously been announced as a member of the 2010 squad, but has left the team by mutual consent.
Commenting on his rider line-up for the 2010 season, BE1 Racing team owner Giuliano Rovelli said: "I'm very sorry that Garry McCoy and my team didn't reach an agreement, and I thank him for his determination and expertise, and for the good results achieved in 2009. I do wish Garry all the best for his career in the future. I'm fully satisfied with this new team in the Supersport World Championship."
Triumph Motorcycles and BE1 Racing will enter four riders in the 2010 Supersport World Championship, including French two-time world champion Sebastien Charpentier, who returns to the series following a two-year absence.
The youthful ParkinGO Triumph Factory Team will consist of British rider Chaz Davies and American Jason DiSalvo, while Charpentier will be joined by Spaniard David Salom in the ParkinGO Triumph BE1 Racing squad. All four riders will be running identical BE1 Racing prepared versions of Triumph's three-cylinder Daytona 675-machine.
Davies, 22, a former winner of the famous Daytona 200 race, joined the squad for the final three races of 2009, scoring a fourth placed finish first time out at Imola. Despite his relative youth, the Welshman has an impressive CV that includes five years spent in the MotoGP paddock and three spent in the American AMA series.
