Max Biaggi has been spotted testing Aprilia's radical new RSV4 World Superbike contender at the Valencia track in Spain.

The Roman Emperor was given special dispensation to ride the bike by his Sterilgarda Ducati team, for whom he has one race left at Portimao in 10 days' time.

The RSV looks like a technical marvel with all sorts of sensors to measure the amount of slip in a slipper clutch, tyre chatter, fork dive plus other stuff like variable frame geometry... and shit.
