A total of 22 riders will take to the track this week to participate in post-season testing at Portimao, as several teams begin their early preparations for World Superbikes 2010.

Each manufacturer will be present in Portugal, save for BMW, with a number of teams taking the opportunity to get acquainted with new riders ahead of an intense off-season of development.

Leading the way is Suzuki Alstare, who will welcome Leon Haslam to the team, the Briton joining Sylvain Guintoli, who marked his World Superbike debut this weekend with a fine run to the top ten in race two.

Many eyes will be on Yamaha too as James Toseland prepares to appear on the title-winning R1 for the first time in Portugal, along with new World Supersport Champion Cal Crutchlow.

Ten Kate Honda is due to test with Jonathan Rea and new signing Max Neukirchner, who will appear on a bike for the first time since injuring himself during testing back in July, while Ducati Xerox will look to get over their disappointment of missing out on the 2009 title by getting ready for 2010 with its unchanged line-up of Noriyuki Haga and Michel Fabrizio.

Aprilia and Kawasaki, meanwhile, will be present with three riders each, the former confirmed to test Max Biaggi and Leon Camier, plus one other. Kawasaki, however, isn't expected to test with Chris Vermeulen due to contract restraints, while Tom Sykes is likely to be sidelined with the injury that forced him out of the final round.

Three privateer teams will also take to the track in Portimao, DFX Corse, Althea Ducati and one other, while Ten Kate Honda will be joined by a further three from the Supersport ranks.

Action takes place from 09.00 to 13.00 and then again from 14.00 to 17.00.
