Giacomo Zannoni was born on February 7, 2008 in Modena and lives in Spilamberto, in the province of Modena. At the age of 6, he got on a minibike for the first time — and has never got off since. He took his first competitive steps in minibikes, where he achieved his first successes.

From 2018 to 2020, he competed in the CNV, where race after race his results continued to grow. He claimed several podium finishes, so much so that in 2019 he reached the national final, finishing second overall.

In 2020, he also won the northern qualifying round, but due to the pandemic the final was not held. In 2021, he moved up to larger wheels on a Kawasaki 400 and competed in the MES — Motoestate — where, race after race, he refined his experience and gradually began to show his potential.

It was 2022 that truly established Jack40. After an outstanding season, he managed to claim second place in the championship.

From 2022 to 2023, Giacomo was the official Dunlop tester for the Italian SS300 category. At the end of 2023, he joined Team E&E Squadra Corse, led by Alessandro Trigila and Paolo Marini.

He is currently competing in the 2024 season in the CIV SS300 category with Team E&E Squadra Corse, where he is performing strongly and, in the two Mugello rounds, managed to climb to the top step of the podium.
