Cal Crutchlow tested a new linkage and suspension arrangement on his Rizla Suzuki GSX-R1000 at Oulton Park, finding more rear end grip and feel. Chris Walker will use the same set-up at Silverstone, one of the circuits he knows well thanks to visiting it in recent years as part of the World Superbike series.

The 2.13-mile long Silverstone International circuit is smooth, flowing and features a twisty infield section that allows plenty of overtaking and action in front of the spectator grandstands. The home of the British F1 Grand Prix and a round of the World Superbike Championship, it is a venue with impressive facilities for teams and spectators.

Rizla Suzuki Team Manager Simon Buckmaster said: "There's no denying Rizla Suzuki has struggled to match the pace of the front runners in the opening two rounds, but we are looking for a turnaround in fortunes at Silverstone.

"More rear end grip, feel and conservation of tyre are what we need and the new link Cal tried at the Oulton Park test appears to have delivered improvements. That and a host of other minor improvements we found during the test should help us compete at the sharp end this weekend.

"Silverstone is a home round for Cal and he will benefit from a lot of local support. Chris should also be on top form as he knows the track well. We desperately want good results for all our fans and sponsors and will be doing our best to deliver."

Superbike racing starts at 1240 on Sunday, April 29th.
