History of the Moto Guzzi MGS-01
The MGS-01 Corsa is a motorcycle built to race. It was first produced by the Ghezzi & Brian special builders on a Moto Guzzi base, and in July 2004 Guzzi presented it under its own brand. It was powered at first by the four-valve engine of Dr. John and later by the BigBore version.

With it Moto Guzzi won the BOTT, Battle of the Twins, at Daytona in 2006 and 2007, the most important race for twins without limits of capacity or modification, and also won the Italian SuperTwins championship in 2006 and 2007. The bike does not exist in a road version, although it can be produced on request in racing form, obviously not homologated and at a cost of about 25,000 euros.
Engine and chassis
The colour is red, like many models of the Mandello company. The original engine of this bike is a 1,225 cc air-cooled unit of 122 hp, though the BigBore used at Daytona in 2007 was over 1,300 cc with more than 165 hp and liquid cooling; the engine uses Cosworth Racing pistons. Although it weighs about 15 to 25 kg more than the classic racing twins of the class, the combination of a good chassis and an engine able to give 9 kgm from 2,800 rpm, with a peak of 11.6 kgm at 6,400 rpm, makes it very competitive.
Over the years the original Ghezzi design was modified, the most visible change being the reduction of the panel under the bike, which made it an almost naked machine.
