Teenage Japanese rider Shoya Tomizawa died on Sunday from injuries suffered in a sickening crash during the San Marino Moto2 Grand Prix.

The 19-year-old - who had won the opening race in Qatar and finished second in the next one in Spain - came off his bike when under pressure from the fast charging Italian Alex de Angelis.

Neither de Angelis nor British rider Scott Redding were able to avoid hitting Tomizawa, who was propelled over 40 metres and off the track into the gravel.

Both de Angelis and Redding appeared to be alright as they groggily got to their feet, but Tomizawa was immediately stretchered away to the medical centre.

Tomizawa, whose form had tailed off after his explosive start to the season and was seventh in the overall standings with 82 points, was taken to hospital 30 kilometres away but was later pronounced dead.

Spanish rider Toni Elias riding a Moriwaki won the race for his fourth successive victory in the category.

The 27-year-old confirmed his place atop the overall standings with his sixth victory of the season beating home compatriot Julian Simon, riding a Suter, and Swiss Thomas Luthi on a Moriwaki was third.
