British Superbike bosses the MCRCB and MotorSport Vision performed an about face on the weight penalty added to 1200cc V-twins after, it seems, Ducati Corse intervened last night - and both Leon Camier and Shane Byrne are on the official entry list for this weekend.
In a statement, the MCRCB said: "MCRCB has received a communication at 7.00pm this evening from Ducati Corse advising that it would be not be safe for the Ducati 1098R motorcycle to race with a dry weight in excess of 168 kilograms without prior testing.
Accordingly and to alleviate the immediate need for the fitment of additional ballast MCRCB Bulletin 2008/6 is superseded by the following.
For immediate application and valid for the event at Donington Park 24-26 May only.
1200cc Twin Cylinder motorcycles conforming to MCRCB Superbike Technical Regulations:
Minimum weight limit 175 kg - applicable for qualifying practice
Minimum weight limit 170 kg - applicable at all other times
All other conditions of article 5.2.3.2 apply.
The change in the regulations by MCRCB is in accordance with Article A.5 of the MCRCB Sporting Code.
The MCRCB will issue a further bulletin under this heading prior to Round 5 of the Championship at Snetterton."
NW200 Ducati's Alistair Kennedy said: "Having spoken to all the senior members of the team including John Hackett, Ken Foley and Michael Rutter, we now believe that the amended weight limit will allow us to participate in Monday's races. This is subject of course to no unforeseen technical problems over the weekend."
Kennedy went on to add that he was relieved that a compromise solution had been reached for this weekend to allow all Superbikes to participate in the races and that it could only be in the best interests of all the teams and especially the thousands of race fans who will attend Donington over the Bank Holiday weekend.
Airwaves boss Colin Wright said he will be able to give his team's view later on today.
