Former Daytona 200 winner Don Emde has memorialized Jarno Saarinen and Renzo Pasolini with a donation to the Roadracing World Action Fund for deployment of soft barriers at racetracks around the country.

Saarinen and Pasolini died in a crash at Monza on this day in 1973 when they hit oil that race organizers refused to acknowledge or clean up despite warnings from riders in a previous race.

The story of the incident that took their lives appears on PartsMag.com, a website which Emde’s company operates for Parts Unlimited.

In making the donation, Emde wrote, “As today is the 30th anniversary of the 1973 tragedy at Monza, I’d like to pledge an additional $500 to my earlier contribution to the Airfence fund.

“If possible please list as: In memory of Jarno Saarinen and Renzo Pasolini, who died May 20, 1973.”
