The Rizla Suzuki team have completed their 2007 post-season test programme with a behind-closed-doors two-day test at Phillip Island.
Both Chris Vermeulen and Loris Capirossi put the new 2008 prototype Suzuki GSV-R through its paces, while the other MotoGP teams are gathered at Jerez for their final tests.
Suzuki chose to travel to Australia due to the technical nature of the circuit.
Both riders carried out a huge test schedule, covering nearly 400 laps or 1,800km between them.
"This has been a very positive test for us and we have got through loads of stuff during the two days," said Vermeulen. "It's quite difficult to gauge how well you are doing with no other riders here, but that has also been a positive thing as we have been able to get on with our job and not worry about other riders or laptimes.
"I know my pace on the new bike was better than the race here in October, but that was not what this test was all about. We were here to find out what would make the bike work better and we have certainly made big steps towards doing that, we have learned a lot that will help us not just at Phillip Island but elsewhere as well.
"It's now just a shame that we have seven weeks off as I would like to continue working with the new bike and making sure we are as competitive as we can be when the season starts next March!"
Capirossi added: "It was a very good test for me. I did nearly 200 laps and got through an incredible amount of work and we have found a good direction to go in. We got though our full test schedule and although we still have some things to improve, we now have a clear idea of what is needed and we are confident that we know how we are going to get there.
"I am really enjoying my time with the new team and it is now sad that we have to have such a long break, but I will come back refreshed and ready to get going at the end of January - I can't wait for my first race on the Suzuki!"
