There are some worried faces in the MotoGP paddock after the second day of the Qatar test. That the Ducati GP15s are fast should come as no surprise, after all, they were fastest on the first day as well.

The trouble is that everyone assumed that the speed of Andrea Dovizioso and Andrea Iannone was down to the fact that they can use the soft tire, which is not available to Honda and Yamaha.

Despite the protestations of the two Ducati riders, who had said they spent all day on the medium tire, the same tire which the Hondas and Yamahas had used, Valentino Rossi, among others, had cast aspersions on their claims, suggesting that their fastest laps had been set on the soft tire.

They weren’t. Ducati’s official press release stated explicitly that the two Andreas had not gone anywhere near the soft tire so far, concentrating on improving the GP15 on the medium tire, the tire they will race.

Ducati’s press officer confirmed this explicitly to the Bikesportnews website. And just to check, I trawled through all the photos I could find of the factory Ducati team: through the official Ducati press website, through the official MotoGP.com website, and through a couple of other media sites. Not a single photo did I find of a tire with a white stripe, the sign of the soft tire. They really did use the medium tire.

Did they or didn’t they? That was the question after Ducati dominated the first day of the test at Sepang. Andrea Iannone and Andrea Dovizioso spent all day swapping places at the top of the timesheets, Iannone coming out on top at the end.

It was an impressive showing, but MotoGP watchers and Ducati’s rivals were quick to pass judgment: of course the Ducatis were fast, after all, they were allowed to use the soft rear tire, a concession for the Open class teams and factories who have yet to win three races in the dry. That tire is worth six or seven tenths a lap, said Valentino Rossi.

Only they didn’t use the soft tire. At least, that is what Andrea Dovizioso told reporters. He spent all day working on race setup, first on the GP14.3 to set a baseline, and then on the GP15 to work on braking set up and electronics.

Things will be a little slow on Asphalt & Rubber today, as we are out near Willows, CA testing the new Yamaha YZF-R3. We will be spending the first part of the day on a 120-mile street ride, and then following that up in the afternoon by riding the new “West Course” at Thunderhill Raceway.

You can follow our thoughts on the bike live via Facebook, Twitter, and Instagram. You can also try searching for the hashtags: #YamahaR3USA & #FirstRideR3 for the thoughts of our colleagues as well.

Yamaha’s entry into the small-displacement space, the YZF-R3 specifically fills a void in Yamaha’s lineup for a small-displacement, learner-focused, sport machine.

Take a glance at the timesheet after the final day and it is easy to draw some simple conclusions from of second Sepang MotoGP test. Marc Márquez reigns supreme, with Jorge Lorenzo is the only rider to get anywhere near to him.

Cal Crutchlow has improved, but at the moment is only fast over a single lap. The Ducati Desmosedici GP15 is fast, but only in the hands of Andrea Iannone. Valentino Rossi and Dani Pedrosa have their work cut out if they are to match their teammates.

Bradley Smith has surpassed his teammate, Pol Espargaro. Suzuki is close, but not quite close enough, while Aprilia is hopelessly lost.

As attractive as those conclusions are, the underlying truth is a lot more complex. Testing is exactly that, testing, and everyone is on different programs, trying different things at different times of the day.

Or as Dani Pedrosa succinctly put it, when asked if he was trying out a new strategy for qualifying during the test, “we were just trying. That’s why we are here.”

When the R1 was first launched it became an instant icon. A tri-axis engine with a GP style chassis was cutting edge technology back in 1998.

The bike has evolved through the years with fuel injection, a crossplane crank, and electronic systems amongst the hundreds of development upgrades.

The original R1 design focus was primarily for the street, however that has all changed for 2015, with Yamaha’s Engineer’s instructed to design a bike mainly for the track.

A team of 50 design engineers worked closely with Yamaha’s MotoGP team and test riders from divisions in Japan, Europe, and the US, including Valentino Rossi and US rider Josh Hayes, to come up with perhaps the most technologically advanced electronics package on a motorcycle ever made available to the riding public.

Many of the senior engineers were in attendance at Sydney Motorsport Park – Eastern Creek in Australia for the R1 world launch, providing excellent technical support for the test riders and a unique insight into the challenges they each faced creating the new R1.

The 4.5km Brabham circuit provided a world-class test track for the 100 journos who descended from all over the globe to experience the 2015 Yamaha YZF-R1 and R1M for the first time.

The diverse range of 18 corners, including one of the fastest turns in Australia, approached at nearly 300kmh, was perfect to test all the attributes of a new motorcycle.

Our test group had some quick guys including Josh Brookes, Steve Martin, and Cam Donald, so there was no hanging about. 

After the excitement and confusion of the first day of testing at Sepang, some semblance of normality returned on Tuesday.

Cooler temperatures and more stable weather meant that riders had much more time to do work on track, the heat and humidity not quite as oppressive as they had been the previous day. The excitement over new bikes and gearboxes had also subsided, and the hard grind continued.

If Tuesday is representative of the normal state of play in MotoGP, then it seems like there are already two favorites for the title emerging from the pack, though margins are slim indeed.

Marc Márquez and Jorge Lorenzo were the only two riders to crack the two minute barrier, posting fast times early-on in the day, then getting back to work on 2015.

Nobody else got near, with the exception of Andrea Iannone, who piled in a quick lap at the end of the day to fall just short of two minutes, the Ducati GP15 quickly proving its worth.

If the purpose of testing in Sepang is to ensure that as little time as possible is lost to the weather, then the first day of the MotoGP test fell well short of its objectives. The Malaysian circuit sweltered under oppressive tropical heat all day, rendering most of the day of little use for testing.

With track temperatures approaching 60°C in the early afternoon, the grip disappeared, and the heat made riding a MotoGP bike a punishing affair.

Then, just as the riders returned to the track as the air began to cool, a tropical thunderstorm washed the track out, with lightning causing the session to be red-flagged for a while. It was not a day in which the teams could get an awful lot done.

That was a shame, as they had an awful lot to do. Ducati had brought the GP15 for its on-track debut, Yamaha had its fully seamless gearbox, Suzuki had unleashed a few more horses from its GSX-RR, and Aprilia had a stack of chassis and electronics solutions to test on track. With on a couple of hours of productive track time, much was left untested.

The international moto-press was gathered in Australia this week, some for World Superbikes at Phillip Island, and others for the 2015 Yamaha YZF-R1 launch at Eastern Creek.

While we’ll have our assessment of the new R1 and R1M for you to read on Wednesday, we thought we would whet your appetite with some on-board footage.

Lapping at the Sugo Circuit in Japan, we get to see the new YZF-R1M go through its paces, quite convincingly we might add, but more importantly, Yamaha has visualized the electronics data coming from the superbike.

Lean-angle and acceleration telemetry comes from the R1M’s IMU, and the graphics also include when the traction control, quickshifter, wheel-lift control, and our personal favorite: slide control, are aiding the rider.

A visual, aural, and technical delight — we think you will enjoy the video, after the jump.

The engineers have had two weeks to pore over the data from the first MotoGP test at Sepang, identify problems, analyze strengths, and find more ways to go faster. Their analyses have been translated into designs, into new parts, into yet more software, ready to put their theories into practice.

On Monday morning, at 10am Malaysian time, the MotoGP riders get to try out all of the new parts and ideas thought up by their factories and teams in search of a few more fractions of a second.

The eyes of the world will not be on what the engineers did between Sepang 1 and Sepang 2, however. Attention will be focused on Yamaha and Ducati, who will be testing hardware which has been a long time coming.

Yamaha is bringing its fully seamless gearbox to the Sepang 2 test, and Ducati will roll out its Desmosedici GP15 for the first time. Both could make a significant impact.

Almost without realizing it, we find ourselves in the midst of a glut of motorcycle racing action. For 11 days, bikes and teams are testing, racing, and being introduced to the public at large. On Monday and Tuesday, the World Superbike teams had their last test of the pre-season at Phillip Island.

From Tuesday to Thursday, the Moto2 and Moto3 teams are testing at Jerez. On Friday, the 2015 World Superbike season gets underway Phillip Island, culminating in the races on Sunday, featuring shock substitute Troy Bayliss.

Then, from Monday, MotoGP returns for three days of testing at Sepang, followed by an extra day with Michelin tires, with the factory riders at the helm.

In between, we have seen the launch of the Ducati Desmosedici GP15, the CWM LCR Honda team is set to be launched on Wednesday, and there is even a presentation here in Holland by Eurosport, in which they will reveal their plans for MotoGP coverage in The Netherlands for 2015.

There is so much going on that there are barely enough hours in the day to actually write about it. Enjoy the cornucopia while you can.

It is something that we have expected ever since we heard of Yamaha’s intent to bring two different variations of R1 to market, so it should come as no surprise then that the Yamaha YZF-R1M has been homologated by the FIM for use in the Superbike & Superstock 1000 classes.

Actually both flavors of R1 have been given the nod by the FIM, though we know that if given the choice, teams will choose to develop the YZF-R1M over the base model, especially as it comes with upgraded suspension pieces and carbon fiber fairings.
