New exhaust for Rossi in Estoril test

Valentino Rossi completed a day of tests using a new exhaust system on his Yamaha YZR-M1 at the Estoril circuit on Monday, whilst Proton Team KR made their first public test using a prototype V4 engine built by KTM.

The Italian, who took victory in the Grande Premio Marlboro de Portugal at the same circuit on Sunday, lapped non-stop throughout the afternoon evaluating the new parts from the time the track opened at 12pm until closure at 6pm local time. Running up a total of 80 laps, Rossi used the new exhaust for the entire session and knocked over a tenth of a second off his best lap in the race.

Rossi was joined on track by Yamaha colleague Carlos Checa, who did not use the new exhaust system. Despite warm and dry conditions at the track, Checa took the opportunity to test out Michelin's latest ‘cut slick' tyres in anticipation of mixed weather conditions at any of the remaining five races, testing out their durability over five quick laps.

After both experiencing problems during the Grand Prix weekend, Honda pair Sete Gibernau and Colin Edwards made the most of a vital chance to continue set-up work on their RC211V machines ahead of a run of five races in the remaining seven weeks of the season.

Whilst Gibernau could only finish fourth in Sunday's race, allowing Rossi to open up a 29-point gap at the top of the championship, he gave a sign of what could have been today, unofficially smashing Makoto Tamada's new circuit record of 1'37.933 with a stunning time of 1'37.63.

Kawasaki team-mates Shinya Nakano and Alex Hofmann were also testing today, whilst Nobuatsu Aoki completed concurrent tests on the hybrid Proton-KTM machine alongside the team's current V5 version. Aoki's best time understandably came on the standard bike but he did run up 21 laps with the KTM engine, setting a best time of 1'43.18.

Unofficial lap times

Sete Gibernau – 1'37.63 (74 laps)
Valentino Rossi – 1'38.31 (80 laps)
Colin Edwards – 1'38.08 (71 laps)
Carlos Checa – 1'38.90 (76 laps)
Shinya Nakano – 1'39.97 (58 laps)
Alex Hofmann – 1'39.97 (64 laps)
Nobuatsu Aoki – 1'41.59 (62 laps).
