Miksi tälläinen niskatuki ei ole enemmän yleistynyt speedwayssä?
Aika harvalla näyttää olevan.
“The fence at Rye House is a fully suspended fence with no permanent posts behind it which riders can hit.
“Previously it was a chain-link fence with 50cm wooden kick boards, but from the 2014 season it will be an air fence in the corners and chain-link in the straights.
“In terms of specific design, the strong metal posts are set well back from the track at each corner and straining wires are stretched tightly between these posts.
“In the corners the straining wires are pulled into a curved shape by short wires pulling at right angles to the main wire and these are held in place by stakes in the ground which do not protrude above ground level (and are therefore no hazard).
“We are using the same principle with the air fence so that if a rider hits the air fence and slides under it, the fence will simply lift and the rider cannot get hurt other than by hitting his own motorcycle. We are sure that for rider safety, it is the best fence anywhere.”
