Kawasaki and BMW Italia are embarking on two days of private World Superbike testing at Motorland Aragon as they look to overcome a disappointing start to their respective 2011 campaigns.
The opening round of the season at Phillip Island saw Kawasaki make its debut with the ZX-10R, but while Tom Sykes posted a pair of solid top ten finishes, both he and team-mate Joan Lascorz had been top five during practice.
BMW Italia, meanwhile, scraped into the points as they made their Superbike debut with James Toseland and Ayrton Badovini, the pair insisting the team needs more testing miles under its belt.
Nonetheless, both it and Kawasaki will get its wish with an outing around the Spanish circuit, which joins the WSBK calendar for the first time in 2011.
Chris Vermeulen is expected to be on track for Kawasaki ahead of his proposed return to action at Donington Park next week, the Australian announcing via his Twitter account that he has been given the all-clear to ride the bike this week.
