Set-up report YZR-M1

The MotoGP World Championship now makes its way to Shanghai, China for the first
time in the championship's illustrious 56-year history. The new circuit, billed
as the "the venue for the new millennium" was completed last year and was used
for the first time during an international event when the F1 circus made its
debut in China. Now it's the turn of the MotoGP boys and the racing promises to
be just as intense as the first two rounds.

The circuit was designed by architects Hermann Tilke and Peter Wahl and its
layout was inspired by the shape of the Chinese character 'shang', which stands
for 'high' or 'above'. Other symbols represented in the architecture of the
circuit facilities originate from Chinese history, such as the team buildings,
which are arranged like pavilions on a lake to resemble the ancient Yuyan-Garden
in Shanghai. One if the circuit's most impressive features is the extraordinary
main grandstand, which hosts some 29,000 seats and provides a spectacular view
of almost 80 percent of the circuit.

Whilst none of the MotoGP riders will have previously been able to test at the
Shanghai circuit until free practice gets underway on Friday morning, its
winding turns and high-speed straights promise plenty of opportunities for
overtaking and are sure to provide more close MotoGP racing in Sunday's
inaugural Chinese Grand Prix. In Valentino Rossi's own words: "I think the
circuit will be very good; it is wide, fast and technical."

The 5,451m track also promises to provide an interesting challenge for the
engineers. With a virtually equal ratio of nine left and seven right-hand
corners, as well as two long straights followed by hard braking zones, the
emphasis will again be on finding a balanced base setting for the Yamaha YZR-M1.
The longest straight runs parallel to the Dragster track between turns 13 and 14
and has a length of 1,175m, which should permit top speeds in excess of 320km/h,
whilst technical corners such as a snail-like narrowing section between turn one
and turn three are unlike any other corner in the championship calendar.

Rossi and his Gauloises Yamaha Team-mate Colin Edwards spent last week's test at
Estoril working specifically on their set-up for Shanghai, making further
progress with the general setting of the 2005 version YZR-M1 and finding a
comfortable base which they will now take to China. Whilst initial gearbox
settings have already been calculated on the circuit layout, both riders will
use Friday morning's free practice session to gather data about the
peculiarities of the track, such as bumps and grip levels, before making
specific adjustments in the build-up to Sunday's race.

The true nature of Shanghai will only reveal itself during the first practice
sessions, but the relatively fast corners that abound around the track will
clearly require stability from chassis and suspension set-up. The track will
demand an almost constant agility at the same time as offering stability driving
off the sides of the tyres - no easy feat without factoring in the many unknown
variables.

The main target will be a good stable turn-in characteristic and a set-up that
offers easy changes in direction; supported by a high level of feel from both
the front and rear. Weight bias will start of as neutral as possible to prevent
the front overloading in the midpoint of the turn, while also ensuring good
drive off the sides of the rear.

Despite 240 plus horsepower power delivery will need to be funneled to provide
the best midrange torque and predictability to drive off the countless turns,
while still factoring in the one kilometer straight. But all else aside, to
finish first, first one must finish - and tyre endurance will be the key.
