The racing at Boretto was cancelled today due to strong winds, however, the UIM has named the 2025 F-125, F-250, F-500 World Champions.
With only one heat run yesterday the organisers are awarding full event points on those heat results.
Adding those to the race held in Bad Saarow, Germany the UIM can now name the F-125, F-250 and F-500 World Champion (subject to ratification).
2025 UIM F-125 World Champion – Joonas Lember
2025 UIM F-250 World Champion – Massimiliano Cremona
2025 UIM F-500 World Champion – Marcin Zielinski
Cremona tied with Nikola Todorov with 37 points, however using the UIM countback rules he was awarded the championship due to a higher number of race wins.
