After a weekend of records at Valencia, thanks to the Pirelli tyres which used to improved the lap records in all the classes, Assen delivered another great performance from the Pirelli tyres. In the SBK class the riders use a qualifing tyre and Bayliss set the new record in Superpole with the incredible time of 1’38.420, having set an even better one in final free practice, 1’38.355. No qualifying tyres were needed for a new pre-race record from the Diablo SUPERCORSA tyre, and Broc Parkes. In the two Stock classes DIABLO SUPERCORSA produced records, with Corti in the 1000 class (a time of 1’41.576 which could let him race in the SBK class) and Petrucci in the 600cc class.
