Alice Ducati's Toni Elias is facing his second weekend in a row without a suitable rear tyre, causing the double 2008 podium finisher to be left just 15th fastest during Friday practice at Sepang.
Tyres unsuitable for the unique characteristics of certain riders is supposed to be a fear for next season, when the new single-tyre rule will see a reduction in the options available, but for Elias the scenario already exists.
The Spaniard, who weighs just 57 kg, says the rear construction Bridgestones available to him in Malaysia are simply too hard.
"I am not happy at all. It is a difficult situation for me, just like in Phillip Island," said Elias, who exploited incidents and accidents ahead to finish eleventh in the Australian GP. "The construction of this tyre is really hard and it doesn't work properly for a rider with my physical characteristics. What can we do? It is what we have and we will try to do our best with it. I will try to invent something to obtain a good placement."
"For security reasons we have a set of tyres that Toni doesn't find suitable for him," explained team technical director Fabiano Sterlacchini. "We are working hard to allow him to find the best feeling possible, but just like in Phillip Island it will not be easy. Unfortunately with his riding style and his light weight, these tyres don't seem to best. We will do our best anyway as always to obtain the best position possible on the starting grid."
Team-mate Sylvain Guintoli, who weighs in at 62 kg, was left one place behind the Spaniard on combined practice times - having struggled with the front of his satellite spec Desmosedici.
"We had too many problems but compare to this morning we have improve a little," said the Frenchman, riding with an injured shoulder. "Tomorrow morning I will try a different front tyre that should allow me to have a better feeling and as a consequence it should allow me to push more. Anyway it will not be an easy weekend for us and all team members inside the garage will have to give their best."
