IN THE WIND P58 CHICANE ISSUES FOR EMBATTLED MONTMELO CIRCUIT V alentino Rossi led calls for a mid-weekend circuit change in Barcelona, after crashes and problems at the new, ultra-tight chicane, installed "for safety reasons," at the Montmelo (Catalunya) circuit. Last year, in an emergency measure after Luis Salom crashed fatally at a corner with insufficient run-off, MotoGP ad- opted the Formula 1 layout, with a tighter hairpin at the end of the back straight and a chicane before the last, fast corner's slowing entry and exit from that section. But the chicane was considered also risky, with not enough runoff and an awkward pit lane entry, and riders re- quested a change for this year. It came in the form of an- other chicane, some 55 yards before the Formula 1 left-right. Some riders—including the factory Honda, Ducati and Aprilia teams—had tested there after Le Mans, and they found the very tight turns at the end of the lap much at odds with the fast and flowing earlier part. This posed a challenge for engineers to find compatible suspension settings. The previ- ous layout, said Marc Marquez, "was more natural. Now it is like two different tracks." But after the first day of practice at this year's Catalunya MotoGP, with several crashes at the new section, riders wanted to revert to the slightly faster F1 chicane, which had the advantage of continuous asphalt, where the new section had been resurfaced in be- tween the two corners. "A chicane like this is not at the level of MotoGP, because it is not track—just a piece of as- phalt put between two tracks," said Rossi. The F1 layout was a backward step anyway, but at least there was one type of asphalt, and properly banked corners, he said. Riders at Friday's Safety Commission meeting agreed with him, and officials decided to revert to the F1 layout for Saturday and Sunday.
