With Alex Hofmann having completed his test programme ahead of schedule yesterday, it was left to Shinya Nakano alone to continue development work on Kawasaki's latest Ninja ZX-RR engine during today's final day of testing at the Brno circuit.
The revised engine, which Nakano tested for the first time yesterday, produces more peak power, but also retains the 'driveability' of the previous incarnation of Kawasaki's 990cc, inline four-cylinder MotoGP motor.
Nakano, together with his regular crew and development engineers from Kawasaki in Japan, concentrated today on evaluating changes to the engine management system, and assessing revisions to the front-end geometry on his Ninja ZX-RR.
The 27-year-old Japanese rider also tested a new specification exhaust during the afternoon session, collecting valuable data for Kawasaki's ongoing development programme.
After a busy race weekend, followed by two days of intensive testing, Nakano will spend a few days at home in Japan recuperating, before starting preparations for his home Grand Prix at Motegi, scheduled for Sunday 18th September.
Shinya Nakano: #56 - 1'59.74 (48 Laps);
"It's been two hard days of testing, both for me and my crew, but we've achieved a lot. We've done a lot of laps on the new engine and, while there is still some development work to be done to realise its full potential, my overall impression has been very positive. It has more top-end power, and the power doesn't drop off so sharply on over-rev. Brno is not such an 'engine circuit' so it will be interesting to see what advantages the new motor offers at Motegi, where I hope to try it again during practice. Overall, although we haven't seen much of an improvement in lap times, it's still been a very productive two days of testing for us."
Ichiro Yoda: Technical Manager;
"This has been a very positive test for Kawasaki. The feedback and data we have collected during these two days will allow us to continue our engine development programme ahead of the Japanese Grand Prix at Motegi. We now have a clear direction for our engineers, and I am confident that we can make further improvements to the engine before the next race. Motegi is an important race for Shinya, and also for Kawasaki, so we are focussing all our efforts on providing our riders with the best possible package for this event. The same is also true of Bridgestone, who have collected a lot of data on Motegi through their involvement in the Japanese championship. I'm sure that the tyres they supply to us for this race will offer some advantages over those of our competitors."
