Further revisions to the Superbike World Championship regulations will see the 1200cc twin-cylinder Ducatis on par with the 1000cc four-cylinders when they hit the scales at Silverstone’s round in Great Britain at the end of the month.

The twins have received their second weight reduction of the season in a bid to chase down the fours on track, the revision announced following the results of race two held at Brno in the Czech Republic on Sunday.

The average value of the event averages over the last three events of the 2010 series – held at Miller Motorsports Park in the USA, Misano in San Marino and Brno – favours the 1000cc four-cylinder motorcycles by more than five points, resulting in a weight reduction of three kilograms for the twin-cylinder motorcycles in the series.

Therefore from the next SBK event that will take place at Silverstone, the new minimum weight for 1200cc twin-cylinder motorcycles will be 162 kilograms, identical to the 1000cc four-cylinders.

The twins started the season with a limit of 168 kilograms, revised to 165 kilos in May after the first six rounds of 2010. It’ll now be up to Ducati to find ways to remove the extra three kilograms from its fleet of factory and satellite 1198 models.
