Notes:
Japanese rider Yasutomo Nagai succumbed to his injuries on Wednesday, 13 September 1995, after three days in a coma from which he never regained consciousness.

His horrific crash occurred on the penultimate lap of the second heat of the Grote Prijs van Nederland, tenth round of the 1995 World Superbike Championship held at Assen in the Netherlands, on Sunday, 10 September 1995. Yasutomo Nagai lost control of his #25 Yamaha YZF750, being thrown into air and landing on the asphalt several meters ahead. In the accident Nagai's Yamaha tumbled over him, fatally breaking his skull. Nagai was rushed to Assen hospital where he remained in a life support system until his death. Nagai was twenty-nine-year old.

According to eyewitnesses reports, Nagai crashed because of the oil spilled on the track by the blown engine of Fabrizio Pirovano's Ducati 916. After the accident the heat was immediately stopped and the final classification was taken by the previous lap, being Carl Fogarty on a Ducati declared the winner.

A native of Koshigaya, in Saitama Prefecture, about 30 kilometers from Tokyo, Japan, Yasutomo Nagai was a Yamaha World Team rider since the late 1980s. He spent his long and successful career competing in the All-Japan Road Racing Championship. In 1994 he was part of the Yamaha France team that won the prestigious Bol d'or endurance race at Le Castellet, alongside the French brothers Dominique and Christian Sarron. He was one of the first Japanese riders to bring on his helmet the famous "big eyes" logo in the international racing circuit.

Contesting the Superbike World Championship since 1994, Yasutomo Nagai achieved four podium finishes, including a third place at Sugo, Japan, just two weeks before his death. He also set two pole positions, at Sugo in 1994 and at Salzburgring, Austria in 1995, becoming the first Japanese rider to win a pole position outside of Japan. He was posthumously classified fifth overall in the 1995 Superbike World Championship, with 188 points.
