Jorge Lorenzo took his Yamaha to a second successive MotoGP victory on Sunday, as tyre management came into play in sweltering conditions at the Circuit de Catalunya. Several riders crashed out as a result of reduced front-end grip, and Lorenzo spoke of the challenge provided by the conditions: “Today was the hottest race this year and physically it was very hard.” He later suggested to Autosport.com that the front tyre may have been “too soft”, while adding that the riders were requesting harder compounds from tyre supplier, Bridgestone. Shinji Aoki, manager of Bridgestone Motorsport’s Tyre Development Department, pointed out that all works riders had chosen to use the softer rear slick, which he said had performed well given the harsh conditions.
