The fourth round of the 2008 World Superbike Championship takes place at Assen on Sunday and for the second year in succession this popular race meeting occupies an early season position on the calendar. The legendary Circuit van Drenthe has been much revised over its long lifespan and the last reduction in its overall length took place in 2006, forming what is now a 4.555km ribbon of asphalt. It still features many unique aspects in its design and layout, including a few trademark positive cambers in some of its untouched corners. The track is now, however, much more like a purpose-built venue than the open road circuit it once was, even if the recent work was entirely necessary to provide much-needed space for spectators and parking areas
