Stuart Easton and Gary Mason are continuing to get acquainted with their new MSS Colchester Kawasaki machinery after conducting a test at Portimao.

The team gave the 2011 ZX-10R its first outing at Cartagena last week before travelling onto the Portuguese circuit for further evaluation with its two BSB riders.

A busy day of testing, which was disrupted by rain early on, Easton - who returns to the MSS fold after two years away - is looking forward to getting more miles on the bike when the team returns to the UK.

"The day has been quite productive for myself and Gary and it has been a hard day in terms of workload but I am feeling happy at the end of it. We have tried pretty much everything including changes to suspension, working on the traction control and changes to the chassis geometry so it was a hectic one for us.

"We had a slight rain shower after lunch but it soon dried out and we could continue pressing on. Now it is time to pack up and head home ready for some more tests on some of the UK tracks."

Though the bike is still running with a Superstock-specification engine, Mason was impressed with the potential of the much anticipated machine.

"I am peaking after these tests over the last week, especially at Portimao with just myself and Stuart on track. [It] has been fantastic, apart from the short shower we had but that soon cleared.

"We concentrated on the front end of the bike today and considering we are using a stock motor at the moment we were doing reasonable times. I am feeling happy and now ready to be let loose on some of the BSB tracks!"
