2004 MotoGP race summary

At Valencia Valentino Rossi secured his ninth and final win of his world
championship winning first season with Yamaha. Down in sixth after a tricky
start he used his improving pace to good effect, winning 0.425 seconds ahead of
second-placed rider Max Biaggi (Honda) and final podium finisher, Troy Bayliss

After a difficult start, when Rossi did not get the drive he wanted, he
immediately set about reducing the margin of advantage enjoyed by early leader
Makoto Tamada (Honda), and on lap six he made a determined inside pass to lead
the race for the first time. A gritty duel between the pairing saw Tamada pass
on turn one of lap seven, leading the ranks ahead of Rossi, Nicky Hayden (Honda)
and Biaggi. To the rapture of the 122,000-strong crowd, Rossi went back into a
final leading position with a pass on the entrance to the last chicane.

Colin Edwards had a less rewarding time at Valencia only finishing in eight
position, still this was enough to secure a very commendable fourth position in
the final 2004 standings.

2005 set-up report YZR-M1

Valencia is a circuit that offers a slightly undulating layout with good camber
combined and an abrasive surface. It has many stop-and-go 90-degree corners,
bumps and a tight design which has claimed many of victims losing the front-end.
This is especially the case with the faster and heavier MotoGP machines. For
this reason riders will be chasing security on this very point, followed by
stability under brakes, while still offering the agility to deal with a circuit
that is more suited to a 250 than a 240Hp MotoGP four-stroke.

The latest spec YZR-M1 offers all the traits that a winning MotoGP bike should
have; agility, drivability off slow and medium speed turns, enough horsepower to
survive on the straights and all of this offered consistently throughout an
entire race. The linear character of the 'big-bang' YZR-M1 power plant is
supported by state-of-the art electronic engine management systems that offer a
much more rider and tyre friendly delivery - making it easier to get on the
power earlier in the turn and with more confidence.

This is essential in the final turn - the run onto the front straight and the
start/finish line. With all of these qualities secured, the main challenge will
be to set-up the bike giving enough front-end confidence on corner entry in
order to not fall victim to a low side crash.

Regarding the geometry and suspension set-up, the Yamaha will have a front-end
lifted slightly, compared to most other circuits, and the rear lowered. Combined
with the right front spring rates and preload, all controlled by the rebound,
this will allow for improved stability under brakes and a planted front-end.

With good camber, except for the penultimate sweeping turn, the ability to leap
the M1 hard off the turns is essential. Especially with the high corner speeds
Rossi likes to carry. To ensure this the rear suspension preload will be set to
prevent an excessive amount of rear-end squat - reducing understeer - while
still offering a plush enough ride to provide good, consistent traction.
