UPDATE: Aprilia and the FIM deny any irregularities with Biaggi’s Aprilia RSV4 at Assen.

Respected source in the World Superbike community, Sport-Bikes.fr is reporting that WSBK technical scrutineers have found an illegal fuel injection system on Max Biaggi’s Aprilia RSV4 Factory at the Assen round of the Championship series. According to World Superbike rules, the entire fuel injection system must be original to the street homologated motorcycle, including the pump, fuel lines, and injectors.

Scrutineering at Phillip Island found that the injectors of all three Aprilias were in compliance, as was also the case for the outlet pressure injection pump, which was checked at Donington Park. However at Assen, Max Biaggi’s RSV4 was found to be different from the bikes used by Camier and Haga, and was racing with a non-original fuel injection pump.

A fuel injection pump seems hardly a worthy offense to crucify the reigning World Champion over, and many will state that pushing the limits of the rule book is a part of racing (something Aprilia is already known for). Accordingly World Superbike has not docked Biaggi of his results from Sunday’s races, nor has it levied any sort of penalty for the team’s actions. Instead, Aprilia has simply been told it much replace the pump by the next race at Monza.
