Matt Oxley takes a closer look into Yamaha's problems...
Zero GP Wins, Fourth In Constructors Championship
"Yamaha last won the MotoGP title in 2021, with Fabio Quartararo. Since
then life has been grim for the Japanese manufacturer, which scored
its last race win in June, 2022. Last season was the first since 2003
that the YZR-Ml didn't win a single race."
Can Yamaha turn it around for 2024? Much will depend on the work of
former Ferrari Formula l engine designed by Luca Marmorini, who has been
building new YZR-Ml engines for a year or so. His first version,
tested at Misano in September, didn't impress Quartararo, who's been
told the final 2024 spec, to be tested at Sepang in February, will be
a major step forward."
"However, even if Marmorini's engines do make more horsepower it's
almost impossible to get the same amount of power from an Inline-4
engine as a V4. And if the bike doesn't have lots of power it's
impossible to run lots of aerodynamic downforce, so it'll have more
wheelies, so acceleration suffers even more."
"For this reason our vision has changed," says Quartararo's Crew Chief
Diego Gubellini. "We want to improve in many areas, not only power. We
are also working very hard on aero to improve turning and to reduce
wheelies and drag [tricky because these factors are mutually
exclusive]. Also, we are working on the chassis to improve turning and
traction. So our picture is that we need a small step in every area to
put everything together and generate a big global effect on the
performance."
"Another YZR-Ml issue is that all its rivals are V4s, which use different
cornering lines, which usually puts them in Quartararo's way, so he can't
use all his speed."
"When I ride alone I can use my riding style," says Quartararo, who
rode heroically through most of 2023. "But when I'm behind I ride
totally differently to basically all the other bikes."
"The only time the Frenchman can overtake is at the end of races, not
because he's better with used tires, but because he's a stronger
rider, so he can maintain his focus and therefore speed longer. "By
the end of races most riders drop their rhythm by maybe 1.5 seconds
from their qualifying speed," adds Gubellini. "There are very few
riders who are, let's say, on another level, who drop only
half-a-second."
Arguably Yamaha's biggest problem is qualifying, because riders have
little chance if they're not on the front two rows- and last season
Quartararo only qualified in the top six twice! "In qualifying the
rider extracts everything from the bike, so your time-attack
performance is limited by bike performance," says Gubellini."
"Quartararo won't test his 2024 engine until Sepang but at least he
liked the new aero he tried in the Valencia tests-an Aprilia-style
front wing and KTM-style seat aero. "The new aero gives less wheelie,"
he said. "But we need to make it help the bike turn better."
"Yamaha has a huge amount of work ahead. And if the latest improvements
don't put the YZR-Ml back on top, what are the factory's choices:
Build a V4 or quit?"
