Yamaha Racing has debuted its “Race-Blu” livery at Misano today. The work of Aldo Drudi (of Valentino Rossi helmet fame), the blue and matte grey paint scheme is the same special color schemes that will be available on the Yamaha YZF-R1, YZF-R6, and YZF-R125 bikes for 2013, seemingly everywhere except the United States.

Yamaha says the livery is a throw-back to its historic racing blue colors of the 1980′s. Factory riders Jorge Lorenzo and Ben Spies will also wear special Race-Blu leathers for the races at Misano and Aragon. Will the special livery prove to be as lucky as the Red/White 50th Anniversary livery? Only time will tell.

For many MotoGP fans, Valentino Rossi’s move back to Yamaha is a welcomed escape from the career-ruining Ducati Desmosedici. The perception, of course, is that the 1,000cc Yamaha is not terribly different from the 800cc-era machine, and therefore Rossi’s return to the tuning-fork brand should mean an instant return to his success and his alien status alike.

When we have these thoughts, we forget that in 2009 Rossi struggled to keep teammate Jorge Lorenzo at bay on the same machine, and that in 2010, right before his leg injury, Rossi was behind Lorenzo in the Championship points (despite a wall being erected in the Yamaha garage). Add in two long years at Ducati Corse, the death of Marco Simoncelli, and a new-generation of GP racers who are just now discovering their full potential, and there is ample reason to believe why Rossi’s return to Yamaha in 2013 will not look like his first venture with the Japanese company, nine years ago.

I suspect the move to Yamaha will be a culture shock for the legion of Rossi’s fans, who during Rossi’s switch to Ducati thought The Doctor’s skills on two-wheels, both on and off the track, could shape the Italian machine into a more tolerable form. The reality of course is that motorcycles are not developed overnight, and for Rossi to be competitive in 2004, changes in Yamaha had to occur far earlier than the signing of the pen to Rossi’s contract.

Light on sponsors, but heavy on style, the 2012 Yamaha YZR-M1 broke cover today at the Jerez. The 1,000cc inline four-cylinder machine will catapult factory riders Jorge Lorenzo and Ben Spies, as well as satellite riders Andrea Dovizioso and Cal Crutchlow on the Monster Yamaha Tech 3 squad, as they attempt to overturn the Honda supremacy of last season.

With more than 240hp at the crank, there can be little doubt that the new M1 will be blisteringly quick, and 220+ mph speed trap times are already being pondered for fast tracks like Mugello. Called the best bike in the paddock by Repsol Honda boss Shuhei Nakamoto, the tuning-fork brand seems set to give Casey Stoner and HRC a run for their money in their Championship defences. Photos and technical specifications after the jump.

It seems only fitting that after reviewing the BRD RedShift SM prototype, that we should turn our attentions to another prototype machine…or should we say, a prototype of a prototype. A glimpse into how lost in the woods Yamaha was with its MotoGP program pre-Rossi, the 2003 Yamaha YZR-M1 prototype is the work of a company desperately looking for a solution against Honda’s very potent RC211V. Employing two Öhlins rear shock absorbers, Yamaha’s philosophy and process of handling over power is very evident in this prototype’s design, though the implementation seems a bit murkier.

Laced with linear potentiometers through out the M1′s chassis, it is at least interesting to note the unit extending from one of the rear shock mounting points to the front of the frame — presumably measuring the flex of the chassis from front to back. With all the data acquisition that is on the 2003 prototype M1, you would think Yamaha would notice one of the most obvious mistakes with the design, namely how the exhaust routing was cramped in with both shock absorbers, surely cooking both units as the machine came up to temperature.

After finishing a very successful weekend at the San Marino GP, the factory Yamaha squad stuck around Misano for another day, and tested the 2012 Yamaha YZR-M1. Though the 1,000cc class MotoGP monster has remained basically unchanged from its debut at Brno, reigning World Champion Jorge Lorenzo and teammate Ben Spies continued development on the bike’s electronics package and overall setup. Misano proved to be a good contrast for Yamaha, as the Italian track’s tighter layout made the extra horsepower from the new M1 less of a factor than it was in the Czech Republic.

“It’s been a little bit more difficult here than Brno, which is a very fast track. Misano is a little bit slower so the difference between the 800 and the 1000 is much smaller,” said Jorge Lorenzo. “It’s difficult to understand the riding style you must use straight away. We’ve made a lot of progress in a couple of hours and the bike has a lot of potential. I’m very excited about the future. We’ve been working on the electronics to help in the braking area but mainly I’ve been getting used to the riding style of the bike and also adapting the bike to my riding.”

With yesterday’s race out of the way, MotoGP’s riders spent their Monday back at the Cardion AB circuit in Brno, testing their 800cc & 1,000cc machines. While we’ve already seen the 2012 Honda RC213V and the Ducati Desmosedici GP12, making its first public appearance was the 2012 Yamaha YZR-M1. Both Jorge Lorenzo and Ben Spies tested the new M1 at Brno; and additionally, the duo also put in laps on their current M1 machinery, which received a more powerful version of their 800cc motor.

With both Yamaha riders happy with the upgraded motor on the 800cc machine, and the package coming together for 2012, Yamaha’s reintroduction into 1,000cc racing can be marked down as a success. However, it was Casey Stoner on his RC213V, with its newly revised chassis for Brno, that was fastest for the day, and easily surpassing Dani Pedrosa’s qualifying time from Saturday during the test.

Also making progress was Mika Kallio on the Suter CRT machine with its BMW motor. The claiming rule team (CRT) has clearly made some improvements, being only 4.3 seconds down on Stoner’s time. Suter still has a long way to go, but can walk away from Brno having saved more face than they did at Mugello a few months ago.

Taken during a Yamaha testing session in Japan, these two videos appear to be our first glimpse into Yamaha’s next MotoGP race bike: the 2012 Yamaha YZR-M1. Though MotoGP regulations will be allowing up to 1,000cc in factory team motor displacement, it is still anyone’s guess as to what displacement Yamaha and the other teams will be running. Likely not to reveal that information until the new M1′s formal launch ahead of the 2012 season, we will still get our first official glimpse of the new Yamaha M1 on Monday.

After the race at Brno, Yamaha plans to test its 1,000cc bike with Jorge Lorenzo and Ben Spies. On-hand will be Honda with its 2012 Honda RC213V, while Ducati will test its 2011 Ducati Desmosedici GP11.1, and not the new GP12. There’s no word yet on what Suzuki will be doing for 2012, though it is widely held that the team will run an updated version of it 2011 machine in a 800cc capacity. A second spy video is after the jump, and though the video quality is poor, the sound of the new M1 is crisp.

Following the Czech GP, Yamaha will debut its new 1,000cc formula MotoGP bike on the Monday. The first public outing of the 2012 Yamaha YZR-M1, Yamaha factory riders Jorge Lorenzo and Ben Spies will get their hands on the new machine, and see how it compares to the current 800cc M1. Also testing their 1,000cc bike on Monday is Honda, which will have factory riders Casey Stoner and Dani Pedrosa behind the handlebars of the 2012 Honda RC213V. Not testing the new RC213V is Andrea Dovizioso, who will be out of contract in 2012, and according to paddock gossip will be in one of the satellite Honda teams with factory support.

On Thursday at the US GP, a day before the general public and non-MotoGP press could get into Laguna Seca, Yamaha unveiled its 50th Anniversary team livery, with a special cadre of legendary Yamaha riders. Eddie Lawson, Kel Carruthers, Kenny Roberts Sr., and Wayne Rainey joined current Yamaha riders Ben Spies, Cal Crutchlow, Colin Edwards, Jorge Lorenzo in the pit lane of the famous American track to commemorate Yamaha’s half-century of motorcycle Grand Prix involvement. After the presentation, a scrum of journalists got a chance to talk to King Kenny about his experience riding the YZR-M1 around Laguna Seca, as Yamaha had built a special GP bike for the American GP Champion, though it did not have a full electronics package.

A&R also got to eavesdrop in on the conversation between Roberts, Edwards, Spies, and Crutchlow, as the foursome exchanged notes on how GP racing has progressed, and what riding the M1 was like coming from different disciplines outside of the usual GP career track. Perhaps most interesting in that discussion was how precise riding a MotoGP motorcycle has become, as the tires, electronics, and suspension all demand a very particular riding style, racing line, and motorcycle setup to achieve maximum performance.

Roberts lamented to the current GP riders because of the precision required, it was easy to run afoul of the M1. Saying in his day, a rider could be 10 feet off the ideal line, fight the bike through the corner, and finish the lap none the slower; but on the current MotoGP equipment, being 10cm off the line can mean seconds missing on the lap time because of how exacting the sport has become.

Helping commemorate its 50th Anniversary of World Championship Grand Prix racing, Yamaha has unveiled special race livery for its factory-backed MotoGP squad, which the team will run at the Assen TT and Laguna Seca Grand Prix. Set to be unveiled Wednesday, June 22nd at the Assen circuit by Jorge Lorenzo and Ben Spies, the Yamaha YZR-M1 WGP 50th Anniversary Edition motorcycles with their red color schemes are described by the Japanese company as paying “homage to the iconic Yamaha Factory Racing liveries of the past with a modern twist.”

Take that as you will, but the new race livery for the two races is a welcomed detraction from the reminder that the Yamaha squad has been unable to field a title sponsor for the 2011 MotoGP Championship season, despite having the 2010 Rookie of the Year Ben Spies and reigning MotoGP World Champion Jorge Lorenzo on-board the squad’s Yamaha YZR-M1 race bikes. Nonetheless, Yamaha has been celebrating its racing heritage with a special 50th Anniversary website, which is well-stocked with images of racing lore for the tuning fork brand.
