Randy de Puniet believes Suzuki is making good progress as the manufacturer continues development work ahead of its MotoGP return in 2015.

The Frenchman is testing the machine at Misano from Monday to Wednesday and said Suzuki had 'made a good step' with a new frame, engine and fairing.

"It was not so easy at the beginning because it is a completely different bike to what I've been using over the last races," said de Puniet, who has been riding the Power Electronics Aspar ART in the CRT class all season.

"In the end the sensation came back quickly. We did a good test, I think; it was a long day but we tried different suspension settings, compared a new frame and a new fairing.

"They have made a good step," he added on MotoGP.com. "Unfortunately, the weather in Motegi a month ago was not so good, but since that test they have brought out a new fairing, the frame and a new engine spec.

"Everything is going well and it is step-by-step. We have time, but the days here will be important."

Suzuki MotoGP team manager Davide Brivio said the test offered a 'good opportunity' to assess the performance of the new machine.

"It is three days of testing because we are a little bit, not behind, but we want to check all of the circuit as much as possible," he said.

"On Monday it was a good opportunity to test with all of the other teams to see the level, even if it is always difficult because they have had the whole weekend; we have to start with the set-up so we are a little bit behind, but that's okay and it is still very good to compare our performance.

"We were previously running two difference chassis. Now we will choose one direction, one of those chassis.

"We also have an evolution of the engine, a different specification."

De Puniet ended Monday's test 13th fastest with a time of 1m 35.097s on the Suzuki, 0.445s behind Ducati's Michele Pirro and 1.833s off the top time set by Marc Marquez.

Suzuki is understood to still be using a Mitsubishi ECU, but is working with the 2014 Magneti Marelli spec system back at base.
