THE motorsport world is mourning the death of Wombwell karting legend Mike Wilson - who helped huge stars such as Fernando Alonso break into the sport.

A six-time world champion, Wilson was a defining figure of karting’s golden era and later became a mentor to generations of future stars.

He died on Monday at the age of 66.

He grew up in Barnsley but moved to Italy when he turned 18 to work with leading manufacturers, becoming a central figure at IAME and Birel.

It was his fierce rivalry with the late icon Ayrton Senna in the 1970s when he really shot to stardom.

History particularly remembers their spectacular clash at Jesolo in 1979, which left the Brazilian with cracked ribs and a long-standing grudge.

Senna later described Wilson as one of the best drivers he had ever seen.

Between 1981 and 1989, Wilson captured six World Championship titles in Formula K (135cc).

Wilson’s retirement from racing in 1989 led him to become a manufacturer with his Rakama brand (MW chassis.

In 1996, he spotted the potential of Spaniard named Fernando Alonso, leading him to the Junior World Title in Genk.

Later, he became the go-to coach for future stars, from Juan Pablo Montoya to Kimi Antonelli and Lance Stroll.

His death is being mourned worldwide and some of the biggest stars have paid tribute to him.

The Mercedes AMG team, of which Mike was a consultant, said: “We are deeply saddened by the passing of Mike Wilson, one of the most influential figures in modern karting, and consultant to our Junior Programme.

“Mike was one of the most successful kart racers of his generation, winning six world titles in the 1980s.

“His greatest impact though came from transferring his knowledge and expertise as a driver to others.

“He played a formative role in developing the careers of so many young racers and was a key part of our Junior Programme, scouting talent and supporting those drivers selected as they progressed on their journey with our team.

“That continued in recent months even as Mike stoically battled illness.

“His warmth, dedication, and passion for motorsport left an indelible mark on the sport we all love and all those who met him.

“Our thoughts and condolences go to his family and friends.”

Alan Brown, who has fond memories of racing Mike, told the Chronicle: “I raced Mike back in the early 70s in the 100cc junior class and back then I remember thinking that he was going to be a world champion.

“My memories of Mike will live with me until the end of time.

“He is a true Barnsley hero.”
