Brembo Issues Statement on Its Master Cylinder Recall

Just over a week ago, we broke the news that a massive recall was coming to motorcycles equipped with a particular Brembo master cylinder. Since then, we have seen recall notices from Aprilia and Ducati (affecting roughly 10,000 motorcycles in the USA) with more recalls expected from other brands. Because recalls in the United States typically come from the motorcycle manufacturer and not the part supplier, mum was the word from the folks at Brembo, though there were a number of questions regarding these recalls that weren’t answered in the NHTSA documents. Today, Brembo has finally decided to speak about the recalls that are underway in the United States, and presumably will be occurring in other markets as well.

Come Drool Over “Kahn” by Mehmet Doruk Erdem

Regular readers of Asphalt & Rubber by now should be well aware of my unrequited love for dustbin-style motorcycles. A&R diehards should also recognize the work of Mehmet Doruk Erdem, as the Turkish designer has penned more than a few concepts that have gone viral on the internet. Today we have another of Erdem’s work for you to consider, a BMW-powered dustbin that is simply named “Kahn”. Based on the Bavarian brand’s twin-cylinder boxer engine, Erdem once again creates an eye-catching shell to house the mechanics of the machine, and hide them from the wind. An eagle-eyed viewer will note a few similarities between Kahn and Erdem’s other most-recent work, which was called “Alpha” and also powered by a BMW engine.

Ducati Now Part of the Massive Brembo Brake Recall

Yesterday we broke the news about a massive recall that is affecting a number of sport bikes with Brembo master cylinders. The first wave of that recall included Aprilia’s two offerings, the Aprilia RSV4 superbike and the Aprilia Tuono 1100 streetfighter. Today, we get our first official word of another manufacturer that is involved with this massive Brembo brake recall, and it is Ducati. With six affected models, spanning four model years, Ducati North America is recalling roughly 8,000 units because the piston in their master cylinder may crack. If you recall our previous coverage, the issue stems from the plastic piston in the master cylinder possibly cracking after hard use. If this happens, the master cylinder can stop operating, which can lead to front brake failure. This is an obvious safety concern

Today Is the First Day of a Massive Brembo Brake Recall

Today is the first day of a massive recall for Brembo brakes, as our inbox just received the first official notice of what is expected to a recall that touches a multitude of brands that use the Italian company’s high-performance line of brake master cylinders. The issue stems from the Brembo’s popular PR16 radial master cylinder unit (the master cylinder that is often paired with the Brembo M50 calipers), which apparently can crack internally at the piston, which can then lead to front brake failure. Because of the physical properties of the piston material used on the master cylinder, and the porosity generated during the injection process used to create them, the piston could crack when used on race tracks, or with frequent ABS intervention, or when the motorcycle falls to the ground.

MV Agusta Buys Back Shares from Mercedes AMG

A bit of a housekeeping item, but today it was announced that MV Holding has completed the acquisition of the shares that were previously held by Mercedes AMG, thus effectively removing the German brand from the Italian motorcycle company’s business operations. This means that MV Agusta is now solely controlled by Giovanni Castiglioni and the Sardarov family, though today’s news is likely due to investments by the latter, into the struggling motorcycle brand. For fans of the MV Agusta brand, this surely is the start of a new chapter for this mercurial motorcycle marque. In case you haven’t been keeping track, the ownership structure for MV Agusta is very complex, and it involves several layers of ownership.

Troy Bayliss Racing in Australian Superbike for 2018

Don’t all it a comeback, Troy Bayliss has been here along, as the Australian never really hung up his racing leathers. Partaking over the yeas in numerous one-off and short-term racing endeavors, the 48-year-old Australian is looking for a little bit more two-wheeled action in his life though, and accordingly has his eyes on a proper championship go. As such, Bayliss has announced that he will compete in the 2018 Australian Superbike Championship, riding with the DesmoSport Ducati team, which he co-owns with team manager Ben Henry, with an eye on the series’ #1 plate. “Initially I did want to see another young guy on the bike, but after I rode it I felt that I needed to contest the championship and try and win myself the elusive Australian Superbike title,” explained Bayliss.

Energica Will Supply FIM Moto-e World Cup Race Bikes

In recent months, the FIM and Dorna have been pushing ahead with the planned FIM Moto-e World Cup for the 2019 season, and today the electric motorcycle racing series took a serious step forward, as it was announced that Energica will provide the spec race bikes for Moto-e. As such, teams competing in the inaugural season of the FIM Moto-e World Cup series will race on modified versions of the Energica Ego street bike model, which will presumably use the production model’s 134hp PMAC motor, and will almost certainly be lighter than the bike’s 570 lbs curb weight. With Energica being owned by the CRP Group, a highly regarded engineering firm in Italy’s motor valley, the company’s ties to Formula 1 and other racing ventures certainly played to Energica’s strengths in the bidding process.

More Rumors About Suzuki’s Turbo Project

I had to go back through the Asphalt & Rubber pages to see when we first heard about Suzuki’s turbocharged motorcycle musings. For the record it was, just over four years ago when the Suzuki Recursion concept was teased at the Tokyo Motor Show. Since then, we have seen a slow trickling of information about Suzuki’s turbocharged project, especially in the time since we got out first glimpse of the twin-cylinder 588cc concept engine. When will the folks at Hamamatsu release this turbo bike? What form will it take? Is it the start of more forced-induction models from the Japanese brand? Or, will it be a one-off model? Does it wheelie? These are all good questions, and if you believe the latest rumors, we have some answers for you.

Is a Baby Africa Twin Coming from Honda?

The Brits over at MCN have an interesting story right now, whereby Honda is considering making a middleweight version of its Africa Twin adventure-tourer. Really, that thought isn’t so shocking, and if this year’s EICMA show was any indication of things, it’s that the middleweight ADV segment is of particular interest to motorcycle manufacturers right now. One look at Honda’s lineup, and it is obvious that Big Red is missing something that can go head-to-head with bikes like the BMW F850GS and Triumph Tiger 800, and the soon-to-come KTM 790 Adventure and Yamaha Ténéré 700. Focused for off-road use, the Honda Africa Twin may not be the pluckiest liter-class adventure-tourer on the market, but it certain is at the top of the pack when it comes to trail riding capability.

About The Rising Cost of Ducati Superbikes

I was a bit surprised when Ducati announced pricing on the new Panigale V4 model. I knew the Italian brand would command a premium for the latest edition of its flagship model, but what took me aback was how high the price had climbed ($21,195) in one swoop, even though prices on the Ducati 1299 Panigale have steadily been creeping upward over the past few years. Part of the blame is surely comes down to simple currency conversion between the euro and dollar, which has also been climbing steadily in the past year (after a sudden and sustained drop for the past three) and is now nearly at its year-long high. When it comes to the US market though, currency fluctuations are only part of the puzzle when it comes to understanding the pricing programs put together by motorcycle manufacturers.

The rain in Japan is separating the sheep from the goats. There are bikes that work well in the rain, and they are up at the front, and there are bikes that don’t, and they are struggling. Including, well, the GOAT, to extend a metaphor.

The 2017 Yamaha M1 simply does not work well in the wet. “Sincerely we tried to do a lot of things with the bike but we are in trouble,” Valentino Rossi said after finishing the day in twelfth, over a second and a half slower than the fastest man Andrea Dovizioso.

“We don’t understand why. Because last year I was very competitive in the wet. I had a good feeling with the old bike. But this year we are struggling. Something strange.”

The problem is mainly wheelspin and rear traction. “We’ve been struggling all the time with rear grip,” Maverick Viñales said, agreeing with his Movistar Yamaha teammate.

“We change a lot the bike during all the practices but finally the same problem remains. It’s been very difficult for us during all of this year trying to be fast and competitive.”

In the week in which MotoGP marks ten years since the remarkable Norick Abe tragically died in a traffic accident (an occasion which MotoGP.com is marking by posting videoes of some of Abe’s career highlights on their Facebook page, news comes of extra Japanese presence at the Motegi round of MotoGP.

There will be at least two Japanese riders on the grid for the start of the race on Sunday, 15th October.

With Australian rider Jack Miller out through injury, the Marc VDS Honda team will be fielding Hiroshi Aoyama as a replacement at Motegi.

The choice of Aoyama should come as no real surprise: the former 250cc champion is one of HRC’s official test riders, and still heavily involved in Honda’s MotoGP effort, and especially with the development of the Honda RC213V.

What happened when Valentino Rossi crashed? How serious is his injury? When will he be back? Who will replace Rossi, if he doesn’t return at Aragon? And what does Yamaha think of Rossi’s training methods?

Yamaha boss Lin Jarvis spoke to a small group of journalists at Misano on Saturday morning, to answer these questions and much more.

Jarvis knew about the accident very shortly after it had happened. “I knew before he got to the hospital,” Jarvis told us. “Albi [Tebaldi] called Maio Meregalli as soon as he got the news that Vale was on the way to the hospital. Maio called me straight away.”

The good news was that Rossi’s injury was not as bad as the last time he broke his leg, at Mugello in 2010. “It’s much less serious,” Jarvis told us, “but probably just as irritating.

Irritating because it effectively means his championship chances are over. So whilst the injury is less serious, the consequences are equally as serious.

Especially now being still very much in the game, being on form, having done such a great race in Silverstone, coming to his home Grand Prix where we tested so well. It’s like a worst possible scenario in terms of timing. It’s a great shame.”

MotoGP is fated not to escape the influence of the weather this season. There has barely been a race which has not been affected in one way or another. Even when it hasn’t rained, it has been stiflingly hot, sizzling tracks causing tires to wilt. So why should things be any different at Misano?

Heavy overnight rain left the track still spotty and damp in patches in the morning, Moto3 getting the worst of it, MotoGP just being left to deal with the occasional stubborn spot of dampness where the water took longer to dry.

It caused a spate of crashes in the morning, and though the track dried nicely and blue skies dominated, it was cooler than normal. When Marc Márquez tried the hardest front tire, that proved just a little too critical, the Repsol Honda rider washing out the front in the final corner.

The rain had also washed any residual rubber from the track, radically altering the grip level. That was a major setback for the factories which had tested at Misano prior to Silverstone, in preparation for this Grand Prix.

“The feeling is completely different than at the test,” Aleix Espargaro complained. “It looks like all the settings we had were not working. The grip is completely different. No grip at all. It feels like ice.”

Does the absence of Valentino Rossi from the Misano race make much difference? It is too early to tell. Certainly the media center feels a little more empty, but this is a trend which has been underway for a while.

Print media has less money to spend, and non-specialist media is increasingly choosing not to report from the race track, taking their information from publicly available sources such as the ever-expanding TV coverage.

Specialist print media and websites are also suffering, though their very rationale depends on being at the track, and so they have little choice.

So maybe a more empty press room is a sign that Italian newspapers have decided against sending a correspondent because Valentino Rossi is not racing. Alternatively, it could just be a sign of a more general decline in media presence.

The paddock feels pretty busy, but then it was only Thursday, and the real frenzy doesn’t start until the bikes hit the track. We won’t really know how badly Rossi absence affects the Misano race until the flag drops on Sunday, and official figures and empty spots on grandstands tell the true tale.

The Movistar Yamaha team have today confirmed that Valentino Rossi is to miss the Misano round of MotoGP. The injury the Italian sustained in a training accident last week is sufficiently severe that he will not be fit for his home round.

Yamaha had widely been expected to withdraw Rossi from Misano, given the fact that he had broken both the tibia and fibula of his right leg, and only had surgery to pin the bones in the early hours of Friday morning.

The day is done and the battle is won. Yamaha claimed its third-consecutive Suzuka 8-Hours on Sunday.

The victory put a stamp on their dominance of the one race each year that the Japanese manufacturers place more emphasis on than any other. As such, Asphalt & Rubber takes a look at the winning machine, the Yamaha Factory Racing Team’s YZF-R1.

Vince Lombardi once said that he “firmly believes that any man’s finest hour is that moment when he has worked his heart out for a good cause and he lies exhausted on the field of battle. Victorious.”

The day is done, the battle is won, and for a third consecutive year, Yamaha lifted the Suzuka 8-Hours trophy.

It was a dominant performance by the #21 crew, and in the aftermath they sat and enjoyed their success. They weren’t exhausted, but for Alex Lowes, Michael van der Mark, and Katsuyuki Nakasuga this was the final moment of their 2017 in Suzuka, Japan.

Sitting in their paddock office, the trio of riders were relaxed, but the emotions of the day were starting to take hold.

Yamaha claimed its third Top 10 Shootout victory on the bounce at Suzuka today, but the Yamaha Factory Team know that there is still plenty of work to do to claim victory at the Suzuka 8-Hours

There are no team sports quite like motorsport. Fans focus their attentions on the riders on track, but it truly is a team effort that drives performance.

At the Suzuka 8-Hours, teamwork becomes even more important, and how a trio of riders work together and gel can become the deciding factor between winning and losing.

Katsuyuki-Nakasuga-Valencia-MotoGP-Yamaha-Racing

Yamaha continues to hand out rewards for its recent win at the Suzuka 8-Hours endurance race, having just granted Alex Lowes a ride on the Monster Yamaha Tech 3 MotoGP bike this past weekend at the British GP, and this coming weekend at the San Marino GP.

Yamaha’s next recipient will be its test rider, Katsuyuki Nakasuga, who will get the honor of racing as a wild card in front of his home crowd at the Japanese GP in Motegi, Japan.

Nakasuga-san is no stranger to the MotoGP paddock, and this year’s race in Japan will be the fifth time that Nakasuga has raced in the Japanese GP.
