Following Fausto Gresini's decision to concentrate in MotoGP class in 2003, Rolfo switched to a team run by Daniel Amatrian, albeit main sponsor Fortuna remains. He went better both in terms of race results and championship finish. He was victorious at Sachsenring and Phillip Island en route to finishing the season in second overall. He went into the final race knowing that victory would give him the title unless Manuel Poggiali finished second, but he was down in seventh. He did beat the series' winningest rider that year, Toni Elías, into third overall however.
