Aprilia is among the manufacturers returning to Jerez later in the week for private testing, when the Noale factory will debut its 850cc prototype on the circuit for the first time. The 850cc machine will run under private conditions at Jerez before the paddock moves to Le Mans for Round 5 on May 8. Ducati ran their GP27 at Misano earlier this month. Aprilia are now ready to fire up their answer.
