2009 Yamaha M1 evolves

“In 2008, when we won everything: the Constructors’ title, the Riders’ title, the Teams’ title, it provoked a great motivation and reaction from rival riders and factories and they must have all started working to produce a bike capable of beating us,” says David Brivio, Valentino Rossi’s team manager. This year, the M1 is an evolution on the proven success of the 2008 bike. Realizing that the lack of new details is a bit boring, Yamaha put together a promotional video that casts Rossi and teammate/rival Jorge Lorenzo as comedic corporate stooges.

“In 2008 the bike was successful, so there was no reason to change the
concept and the new bike is very similar to the previous one. Changing
to Bridgestone tires during the season, it became clear that the
adjustments required were different from the previous set up. So, the
new bike can have a wider range of adjustments,” reveals Lorenzo’s
manager Daniele Romagnoli. “This allowed us, during the latest tests,
to try different geometries, which improved acceleration after corners
because we managed to increase the contact of the front tire with the
ground. We’ve also worked on engine management controls and maps, which
enhance acceleration; our riders can open the throttle a few meters
earlier.”

“Valentino also worked on the engine and noticed an improvement in
acceleration, and he said we are working in the right direction.”

The two Yamaha riders remain fierce rivals. For 2009 the wall that
separates the two riders’ pit garages will remain in place, denying
each the ability to study the other’s bike setup.

Indeed, Rossi rates Lorenzo as one of his chief challengers in 2009,
saying, “I think that the number one rival will be Stoner. Then also
Pedrosa will be very fast, and of course Lorenzo. [Lorenzo] has a
year’s more experience and this year there is also the monotire, so we
will start equal. He will be a very hard rival to fight.”

The only thing that puzzles us in all this carefully prepared corporate
cardboard is the lack of Rossi’s Monster Energy sponsorship livery on
either his bike or kit. We can’t wait to see what spin the notorious
mischief-maker is able to apply to Monster’s trad logo.

    New number for Lorenzo (99) this year also. Maybe some superstition associated w. last year’s 48?

  • rockhound

    I always wonder why we don’t see more development on aerodynamics, especially in the area around the front wheel. It seems to me that engine, chassis and tire design are nearing the limits of what is possible.

  • rockhound

    what is that red tube running parallel with the forks?

  • Juan

    Those are the brake lines (rigid telescoping).

    • rockhound

      well I thought so too. but there’s another line wrapped around the fork tube that connects to the caliper. and it’s only on the right side.

  • http://artistruth.livejournal.com will

    I wonder what the aero regulations are for that front wheel.

  • monkeyfumi

    Telescopic brake lines? No, they are the linear travel sensors for the suspension.
    Lorenzo changed to 99 after leaving his long time manager (who I beleive also raced under number 48)

    • rockhound

      this makes sense, for telemetry i presume. or possibly a dynamically controlled suspension system?

  • Spartandude

    Aero improvements for the front end culminated in the almost mythic “dustbin”. Unfortunately the skill, suspension, and rubber of the rest of the package was not up to the task and multiple deaths insued. Prompting the FIM to ban said improvements due to the frontal point of wind pressure making the bikes highly unstable at even small amounts of yaw, steering angle restriction, and stability in crosswinds (look it up in wikipedia as I am just plagerizing them).
    The notable exception seems to be the Rhyno fender which increases front wheel contact force and reduces wind resistance (www.rynofender.com). Pity my woman think I will kill myself with a sportbike and it just doesn’t go with my cruiser.
    Hope this helps.
    Peace.

    There’s a small ‘Monster’ decal visible on Rossi’s helmet chin and the ear of the visor.

  • rockhound

    Surely by now, someone has to have figured out a way to control the air flow around the wheel. It would be hard to imagine that the shape of the wheel, brake calipers and forks is by some incredible stroke of coincidence the most efficient design.

    Did anyone realize that Packard Bell is still in business?

    From a designer’s point of view: Too bad they screwed the powerfull black/yellow contrast on 46 number on the front. Now you can’t even see it with white background. What a silly decision on such a high level. I’m amazed 0_0

    the 09 livery is boring……… the 08 livery was awesome
