On the All-New R1
After working hard to make the first race version of the 2007 YZF-R1 ready for a two day Pirelli Development Teams' test at Valencia, the Yamaha Motor Italia team enjoyed two positive days of work under clear Spanish skies.
Troy Corser set a best
of 1'34.9 with a race set-up, with Noriyuki Haga on a 1'35.1, on qualifying tyres.
Both existing team rider Haga and new signing Corser made back-to-back evaluations of the 2006 and 2007 models, and despite the '07 model being in its very first stage of development and testing, each rider found real improvements in the performance of the new machine.
Haga spent his time on the new machine, while Corser moved on to the '07 machine after riding most of day one on the previous model. The fastest rider in the test was Max Biaggi (Suzuki) who set a fastest lap of 1'33.9 on race tyres.
Noriyuki Haga (Yamaha Motor Italia):
"We started yesterday just making a shakedown test on the new '07 bike. Compared to the '06 bike it was a good start. It's already quite a good bike and of course we are only at the first step. We have understood what we need from this test and I am sure it will be even better in Qatar. The feeling from the bike is different, front and rear, and it turns a little bit better than the '06 bike. The '07 engine is easier to control because the feeling from the engine is good, although right now we only have one specification of race engine. We need to make some adjustments to the mapping and the take it from there”.
Troy Corser (Yamaha Motor Italia):
"We tried some new swingarms and experimented with the length of the bike, but even considering that, out lap times weren't so bad. This was our first day with the new bike because on day one I hardly touched the new bike. For a first full day on the new bike I think we have got some good info to take away and prepare for the Qatar test. I think the new bike overall is maybe already a little bit better than the fully developed '06 bike. And we have only just started. The '06 bike feels a bit more nervous, and the new one feels easier to ride overall. It feels more stable under braking, even thought he '06 bike was good in that respect too. The '07 just feels even more stable again. We are still working on the throttle but already the '07 engine pulls right through the midrange to the higher revs. It just feels more linear. We tried some new versions of the development tyres and found an improvement with both front and rear. I'm pretty happy."
Massimo Meregalli (Team Coordinator - Yamaha Motor Italia) :
"We can only think of this test as a positive one. To do so many laps and have so few problems was great. In the end we used the new bike all day on the second day and Troy was faster on the new bike when compared to the old one. We are quite optimistic because we didn't expect this. Because the bike is new we can expect to experience a few problems. The bike was finished only on Saturday night and after we had run in the engines and checked that everything was working we put them in the trailer and drove straight to Valencia. So we were expecting a few small problems, as usual when all is new. When we go home will have a lot of data to check and we go to the next test with good experience from this first one."
