Nakano's ability as a development rider has been refined over the years, following spells at Yamaha, Kawasaki and Honda, and while his move to Superbikes doesn't necessarily mean the transition will be seamless, Aprilia are still getting one of the most consistent MotoGP riders of recent years.
Although it has been difficult to predict how capable the RSV-4 is during testing, crucially for Nakano, he has been matching - and occasionally beating – WSBK race winning team-mate Max Biaggi.

Luca Scassa – Pedercini Kawasaki
Although his arrival on the World Superbike scene is unlikely to have caused too many second glances amongst those without an intimate knowledge of the motorcycle racing, Luca Scassa nonetheless arrives armed with a Superbike title under his belt.
While the Italian Superbike Championship doesn't have the same kudos as its British or American counterparts, Scassa is at least notable for having won it with the iconic MV Agusta brand.
