Aprilia V4 testing in Jerez
Aprilia has been testing its prototype V4 World Superbike at the Jerez GP tests this week.
Alex Hoffman has been riding the latest version of the prototype. The former MotoGP rider was riding the motorcycle on track when the weather was too bad for the 125 and 250cc GP machines to use the circuit. We'll bring you pictures and information as soon as it becomes available.
