Race 1 for World Superbike at Monza proved to be an interesting affair this Sunday, as the race was ultimately cancelled for safety reasons. Starting normally under dry conditions, riders took to the track on slicks, only to have the race red-flagged two laps after its start.

While the WSBK paddock scrambled for a restart under wet conditions, riders lead by Carlos Checa had a meeting on the starting grid after the sighting lap. Realizing that parts of the track were damp, while others were dry, concerns returned whether the Pirelli rain tires would be able to go the race distance, as they had lasted for only several laps during Saturday’s Superpole.

World Superbike is in Italy this weekend, getting ready to race one of the fastest circuits on the WSBK calendar. Already hitting 205+ mph down the main straight at the first practice session (208.03 mph for Mr. Fabrizio), the Pirelli racing slicks also have to contend with sweeping fast corners at Autodromo Nazionale Monza.

Highlighting the heat, speeds, and stresses that its tires have to go through while racing at this beloved Italian circuit, Pirelli has put together a short video that outlines what the Italian tire company has to contend with at this special World Superbike round. Interesting stuff.

What a difference a tire makes. Last season in each of Cal Crutchlow’s rider debriefs that I attended, the topic at some point came around to the Bridgestone tire and how treacherous it was during warm-up. Once the tire reached operating temperature, it was fantastic if the rider could keep it hot enough. But until it gathered enough heat, it was flat out dangerous, as so many cold tire high-side crashes proved in 2011.

Crutchlow was one of the most outspoken riders in asking Bridgestone to change the tire design, which they have done for 2012. This year’s control tire warms up much faster, allowing riders to get through the early laps of a session without a dramatic high side, of which we had none in Qatar.

Bridgestone has announced that they are going to bring forward the introduction of a new 2012-spec front tire, and start allowing riders to use it starting from the Jerez round of MotoGP. The new tire was tested extensively during the pre-season, with versions tried at both Sepang tests and at the IRTA test at Jerez. The tire features a modified construction which allows it to heat up more quickly as well as provide more feedback to the riders.

The selected construction was one of two types tested during the pre-season. The two types – designated as “21″ and “24″ – differed only slightly, the central section being slightly less rigid in construction on the 21, when compared to the 24. The riders were positive about both types, but were split on which tire was best. The majority of the riders preferred the 21, praising it as having better stability and feedback. Surprisingly, the Honda riders took the opposite view, saying that it was the 24 which was the more stable tire, the 21 providing less stability under braking.

The Motorcycle Industry Council’s Business Advisory & Forecast group has issued a report that predicts a sales decline in the US new motorcycle market for 2012. The news comes fresh on the heels of the 0.3% gain that the motorcycle industry’s leading brands experienced in 2011 in the American market, and is the first time that the MIC has forecasted future new motorcycle sales for the United States.

Adding some validity to the report is the fact that the MIC, in conjunction with the Institute for Trend Research, accurately predicted 2011′s modest sales growth. This news is interesting to note, as it goes counter to news about the recovering economy and the increased national average gasoline price, both of which have been linked to previous bumps in volume for motorcycle sales.

Head of Ducati Corse, Filippo Preziosi is a busy man under regular circumstances, and with the shenanigans going on in Ducati Corse’s MotoGP team right now, the former motorcycle racer is a hard man to get a word with, let alone on a race weekend in Brno. Somehow catching up with Preziosi during MotoGP’s Brno test, our friend David Emmett at MotoMatters, along with several other journalists, sat down with Ducati’s Maestro of MotoGP to ask him about where the Italian team was headed, and the challenges it is currently facing.

There is of course a tremendous amount of chatter going on in the MotoGP paddock about Ducati’s “frameless” carbon fiber chassis, a switch to an aluminum twin-spar frame, the Bridgestone tires, and Valentino Rossi’s psyche, all of which Emmett has already summarized for us in his detailed analysis of Ducati Corse’s situation. Taking on all of these issues, Preziosi sheds some insight on what is going on behind the scenes at Ducati, and is candid about what issues they are and are not facing.

Dismissing out right that the “L” engine configuration is at least partially to blame for Desmosedici’s lack of front-end feel, one of the more interesting points Preziosi makes is his preference for the v-twin motor. Acknowledging that the package will perhaps make less power/torque than a four-cylinder, Preziosi opts for instead the two-cylinder’s rideability, and if the rules allowed it, the motor’s weight advantage over the inlines (this of course coming from a man who has figured out how to make a v-twin without the weight of a traditional frame).

His comments raise some interesting thoughts about the way rules are constructed in motorcycle racing classes, and perhaps speaks to the central issue occurring MotoGP: that the rules are pigeonholing the development of GP motorcycles into one particular slot, that just happens to be a four-cylinder motorcycle with a conventional frame that reacts to a prescribed tire construction methodology. Preziosi makes some other interesting comments that read well between the lines, check them out in transcribed interview after the jump.

The obvious point to make in the 2011 MotoGP Championship is that Ducati Corse is struggling to compete with Yamaha and Honda, despite having the G.O.A.T. himself, Valentino Rossi, riding for the Italian squad. The recent history of the Desmosedici is fraught with bullet points of issues, most of which coming back to the bike’s notoriously vague front-end. Though showing moments of promise, even brilliance, including a World Championship with Casey Stoner at the helm, the Ducati Desmosedici has earned the reputation as a career-ender and a confidence destroyer among its less fortunate pilots.

When the dream team of development came to Ducati, in the guise of Valentino Rossi and Jeremy Burgess et al, the talk before the 2011 season was that the nine-time World Champion and his perhaps even more impressive garage crew could have the Desmosedici figured out in no-time at all. With the now infamous quote from Burgess that the GP10 could be sorted out in about 20 seconds still resonating in the MotoGP paddock, we stand now well over half of the way through the current MotoGP season, and the Championship standings hide what’s been apparent from day one: the Desmoproblema requires more than a quick-fix.

The solution to fixing the Ducati Desmosedici can be broken down into three camps, and depending whose opinion you solicit, you’ll get one of the following causes for Ducati’s uncompetitive season: the motor, the chassis, or the rider. Walking us through that analysis is our good friend David Emmett (bookmark his site MotoMatters.com right now), who may not be the most astute automatic transmission driver we’ve ever seen, but when it comes to comprehensive MotoGP analysis, the man is second to none.

Putting together an exhaustive digest on the issues that are surrounding Valentino Rossi, Ducati Corse, and the Desmosedici, Emmett weighs and measures the different dynamics of the problem at hand. Head on over to MotoMatters with your beverage of choice in-hand, and hear what MotoGP’s most-enlightened journalist has to say on the biggest subject in MotoGP.

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.

Pirelli will remain the sole-tire supplier for the World Superbike series through 2015, a continuation of the relationship begun between the Italian tire company and Infront Motor Sports in 2004. Along with supplying the Superbike class, Pirelli will continue to supply World Supersport, the Superstock 1000 FIM Cup, and the UEM Superstock 600 European Championship through the end of the 2015 season as well.

“We are delighted to be able to renew the contract with Pirelli until the completion of the 2015 season. Eight years of working together have provided results that go way beyond our highest expectations. Once again we can count on a tyre supplier, whose commitment to the product, service and development is second to none,” said Paolo Flammini, CEO of Infront Motor Sports.

Dunlop, the IRTA, and Dorna inked a deal this weekend that sees the British tire manufacturer as the sole-supplier of tires for the upcoming Moto3 Championship, which will replace the 125GP series in 2012. With the deal good through the 2014 season, Moto3 teams will run Dunlops for the next three seasons, just as the Moto2 Championship has done. Speaking of Moto2, Dunlop saw its contract in that series extended to 2014 as well, and we wouldn’t be surprised if the two items were part of Dunlop’s ability to put together a more competitive bid than other tire manufacturers.

With Bridgestone set to supply tires in the 2012 season for MotoGP, Dunlop still only accounts for two of the three GP series, but we expect that a sole-supplier for Moto3, Moto2, and MotoGP will emerge in the coming years. Single-tire rules were put in place not only to help level the playing field between competitors, but also to help reduce development costs for manufacturers, and logistical costs for tire suppliers. If a single tire company provided all the grid’s tires, that overall cost would likely drop further, something Dorna has been keen on lately. Whether it makes for better racing though, we’ll let you decide in the comments.
