Shaun Muir Racing's new rider line-up of Michael Laverty and Tommy Hill has given its new Yamaha machinery a successful shakedown during pre-season testing at Spain.

Having swapped from Honda CBR1000RRs to manufacturer-backed Yamaha R1s over the winter, Laverty and Hill were given the first chance to sample the bikes during a test at Calafat.

After spending the day getting acquainted with both bike and track, Laverty was pleased with his first impressions on the Swan-sponsored bike and is looking forward to continuing refining the set-up on day two of the test.

"It has been a good day and as an initial shakedown we have done some good work. We mainly worked on the fundamentals and positioning this morning before really making any major changes and towards the end of the day our last few runs were showing improvement, which shows the potential for when we really start pushing on.

"We are going to start looking at working with the electronics and the suspension now that we have done the basics. The Swan Yamaha is really an advanced bit of kit and I am finishing the first day happy, so we are looking forward to getting back out."

Laverty's sentiments were echoed by Hill, who - like his team-mate - is switching from Suzuki machinery this year.

"I have a great feeling from the team and bike already even after the first day; obviously the bike is going to feel very different to what I have previously ridden, but my initial reaction is that the Swan Yamaha is impressive.

"We started on the basics today to keep things simple and then we will gradually introduce electronics very slowly so that we know what we are improving. Tonight we hope to iron out a few little teething problems we had with the quick shifter, but so far we are happy with the progress."
