Simon Antony Wigg (15 October 1960 – 15 November 2000) was an English speedway, grasstrack and longtrack rider.

[4] After relocating with his family several times as a child, he gained a scholarship to Woodbridge School in Suffolk, where he and his brother began their interest in motorcycle racing, attending Ipswich Witches meetings at Foxhall and riding in grasstrack competitions.

The Oxford team had returned to the British League and the other signings to start as the top five riders for the season were Hans Nielsen for a record £30,000, Marvyn Cox for £15,000, Melvyn Taylor for £12,000 and Jens Rasmussen, with Ian Clark and Nigel Sparshott at 6 & 7.

[11] Also in 1985, he became the second British World Longtrack Champion (Michael Lee was the first in 1981) and went on to win the title a further four times.

[5] After suffering epileptic seizures in November 1998 and January 1999, which were originally attributed to head trauma from racing crashes,[15] he was diagnosed with a brain tumour, and had surgery to remove it in May 1999.

[5][16] After recovering, he moved with his family to Gold Coast, Queensland, but after falling ill again in February 2000, returned to the UK for further surgery after discovering that the tumour had regrown.
