2008 Desmosedici RR

2008 Desmosedici RR

The Ducati Desmosedici RR is a limited production road-legal version of the Desmosedici MotoGP racebike.

Ducati made 1,500 Desmosedici models for public purchase. The bike was launched at the 2006 Italian MotoGP event. The entire 500 unit allocation for the United States sold out in five hours.^{[citation needed]}

In 2004, Ducati announced that a low volume bespoke replica of the Desmosedici would be available beginning in 2006. Termed the Desmosedici RR (Racing Replica), it was claimed to be the first true road replica of a MotoGP racing bike. Priority for ordering was given to Ducati 999R owners, with production projected at one bike per day at a retail cost of US$72,500^[2] and GB£40,000.^[3] The price included a three year warranty and servicing, cover, and a racing kit including a race-only exhaust system, a slip-on muffler, and complementary fuel and ignition mapping in a "race ECU". It also included enough sponsor stickers to fill both sides of the bike.

The bike was eventually launched at the 2006 Italian MotoGP event at Mugello, with production beginning in December 2007 and the first customer orders delivered from January 2008.
