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.

It is another winter testing period for the MotoGP riders, and that means that Valentino Rossi has another special “Winter Test” AGV helmet design for us. This year, The Doctor takes his inspiration from Huichol bead art, after he visited the region on a recent vacation to Mexico.

As such, Rossi’s winter test AGV Pista GP R helmet features a hand-painted bead design that plays on the winter motif, with the Italian’s usual affinity for symbols.

What conclusions can we draw from the first MotoGP test of 2017 at Sepang? Well, it’s the first test of 2017, and the factories still have the best part of two months to refine their bikes before the season starts in earnest in Qatar.

Any conclusions we draw are at risk of crashing headlong into reality at the end of March. But with all that data from the test available, it is hard to resist the temptation to dive into it and read the tea leaves.

To make some sense of the timesheets from Sepang, I examined the lap times of the fastest thirteen riders at the end of Wednesday.

The reason for selecting Wednesday was simple: as it was the last day of the test, the riders were all fully up to speed, and the teams were putting together the lessons they had learned on the first two days, selecting the most promising parts to develop going forward.

It was also the day when most of the riders did long runs, especially as conditions allowed it, the weather staying almost completely dry all day. That meant that the riders had a chance to do some long runs, though only Jorge Lorenzo actually ran full race distance in one go.

The reason for selecting the top thirteen riders, rather than doing it for the entire grid, was simple. The top thirteen riders included all of the favorites for the 2017 season (and eight of the top ten from 2016), bikes from five of the six manufacturers now in MotoGP, and two of the four rookies for 2017. It also includes Casey Stoner, Ducati test rider and still one of the fastest men on two wheels.

To draw any kind of meaningful conclusions, I first had to filter out the in laps and out laps, as well as any slow laps which rendered them useless. I used 2:02 as a cut off point. Any laps slower than that were deemed to be too slow for consideration.

That is roughly representative of recent race pace at Sepang. (For comparison, Dani Pedrosa’s winning race pace in 2015 features 16 sub 2:02 laps, his pace only dropping above that on the last three laps.)

What We Learned at the Sepang MotoGP Test, Part 2

02/03/2017 @ 10:15 am, by David Emmett6 COMMENTS

While Maverick Viñales and Marc Márquez emerged from the Sepang tests as clear favorites, with Valentino Rossi, Dani Pedrosa, and Andrea Dovizioso close behind, Andrea Iannone established himself as a genuine dark horse. The Italian was fastest on Tuesday, and left the test as second quickest behind Viñales.

Iannone has inherited a bike that is already well developed, and Suzuki brought engine upgrades to Sepang, which got them even closer to the front.

It was telling that Iannone did not spend much time testing parts, but rather focusing on race setup and working on extracting maximum performance from a used tire.

Tires were a bit of a problem for Iannone on the last day of the test. He crashed three times, including once as he was attempting a long run, the front washing out at Turn 1. The issue proved to be a vibration in low speed corners.

“I have a small vibration in the slow corners,” Iannone said. “In the fast corner the bike is perfect. There is no vibration, no chattering. But in the slow corner, especially in turns four, nine, 14 and the last corner, we have a small vibration at maximum lean angle.” That vibration got worse as the tires became more worn.

What We Learned at the Sepang MotoGP Test, Part 1

02/02/2017 @ 9:48 pm, by David Emmett10 COMMENTS

What did we learn from the Sepang MotoGP test? More than we thought we would on Sunday night. The forecast was grim: plenty of sporadic rain and a track that wouldn’t dry quickly promised three wasted days.

But by the time the teams packed up on Wednesday night, after nearly a full day of testing, Sepang had turned out to be both productive and instructive.

After three days of testing it is clear just how close the field is this season. The top ten riders are separated by just four tenths of a second. Sixteen riders are within a second, from Maverick Viñales in first to Hector Barbera in sixteenth.

The top four riders are on four different manufacturers, less than two tenths apart, and there is a good mix of manufacturers throughout the top of the timesheets.

The two exceptions are Aprilia and KTM, but there is hope for them too. Aprilia made huge strides last year – Aleix Espargaro is thirteenth, 0.740 behind Viñales, and two whole seconds closer to the front than Stefan Bradl and Alvaro Bautista were at the same test last year – and now basically just lack horsepower.

KTM is in its first season in MotoGP, but is already closer at Sepang than Suzuki was at its first Sepang test in 2015. The level in MotoGP is now unbelievably high, and unbelievably close.

Sepang MotoGP Test Tuesday Summary

01/31/2017 @ 12:58 pm, by David Emmett10 COMMENTS

What looked like a wasted day quickly turned around at Sepang. Tuesday started wet, the streets and circuit taking a while to dry after Monday evening’s torrential rain.

Sepang’s weakness was once again exposed: the track took a long time to dry, wet patches remaining on the track for several hours. It was not until 1pm that a few riders started to venture out, and by 2pm, the track was full with riders trying to make up for valuable lost time.

Some riders made use of the conditions, as far from ideal as they were. Jorge Lorenzo put in ten laps in the wet, and Johann Zarco put in eight laps. The reason? To help build confidence, for Lorenzo in the wet, for Zarco, to try to figure out what a MotoGP bike is capable of.

Zarco rode a pair of wet tires to destruction, feeling how the soft, moving rubber exaggerated every movement of the bike. It served as a sort of magnifying glass for how a MotoGP bike behaves, amplifying the feedback and making it much clearer to fully understand, Zarco explained. By the end of the run, he had learned a lot, and made a massive step forward.

How much difference had it made? When the red lights came on for the end of the session, Zarco’s name was still fifth on the timesheets, the Monster Yamaha Tech 3 Yamaha rider less than a tenth behind Valentino Rossi, and half a second behind Maverick Viñales in second.

The Frenchman had found a way of understanding where the limits lay, without pushing himself over the edge.

Sepang MotoGP Test Monday Summary

01/30/2017 @ 2:09 pm, by David Emmett3 COMMENTS

On a normal day, the fastest rider at the end of a day of testing is paraded proudly in front of the press, and given his chance to explain what a good job the team and manufacturer was doing, how they were not really pushing for a lap time, and feign a certain modesty while privately gloating at how they crushed their rivals.

But this was not a normal day. The fastest man in Sepang on Monday slipped out of the circuit in virtual anonymity. After all, he is merely a test rider, and test riders don’t usually talk to the media. We journalists, snobs that we are, don’t waste our precious time on test riders.

In this case, however, it was not the media not wanting to talk to the test rider, it was the test rider not wanting to speak to the media.

One of the reasons Casey Stoner retired from racing was because he was sick of the media circus, of spending his life living out of a suitcase and answering stupid and prying questions from idiots like me.

But he still loves challenging himself on a MotoGP bike, and trying to see just how fast he can go. And Ducati are happy to pay him handsomely for the privilege. After Monday, who can blame them?

2017 Sepang MotoGP Test Preview

01/30/2017 @ 1:39 am, by David Emmett1 COMMENT

In a few hours time, the grandstands at the Sepang International Circuit will echo with the booming assault of MotoGP machines being pushed to their limits. The entire MotoGP grid has assembled for the first test of the preseason, meaning that the 2017 MotoGP season is about to get underway, at last.

That, at least, is the plan. The reality is that the grandstands may echo only to the sporadic rasp of a MotoGP bike being warmed up, and the occasional intrepid test rider being sent out to test conditions.

The resurfaced Sepang continues to be plagued by drainage problems, water remaining on the track for a long time. In high humidity, relatively low track temperatures and without the burning tropical sun, the water left by unusually heavy rains is not evaporating.

Parts of the track remain wet all day, making it impossible to push the bikes to the limit, and very risky to try.

Suzuki team boss Davide Brivio expressed the concerns shared by most teams.

“You never know how many hours you can test, because the track remains wet for a long time. And if it rains a lot in the evening, maybe you have to wait a long time in the morning. So it’s a little bit of a question mark now, how much you can test.”

2017-valencia-test-jack-miller

With just ten days to go until the winter test ban comes in to force, on December 1st, teams in both world championships are busy doing their last tests and collecting as much data as possible to take into the winter break.

Testing is already happening on Monday, with some of the World Superbike teams gathering in Jerez. Kawasaki, the SMR Aprilia squad, Althea BMW, and Ten Kate (soon to be Red Bull) Honda are at the Jerez circuit, though the wet weather means there is little going on on track.

Ten Kate are without Nicky Hayden, who has twisted his knee while practice dirt track. The WorldSBK teams are due to stay for a couple more days, and will hope that the better weather forecast for later in the week arrives sooner rather than later.

Test-Valencia-MotoGP-2015-Tony-Goldsmith-5359

The 2017 season is starting to take shape. After the announcement of the provisional 2017 MotoGP calendar in the run up to Aragon, Dorna published the schedule of official tests for the 2017 preseason. Like the race calendar, the test calendar looks remarkably similar to last year.

Testing kicks off after the final race of 2016 in Valencia, and as last year, the riders get a day off between the race and the test, with the bikes taking to the track on Tuesday.

Up until last year, the test had always started on the Monday after the race, but that was changed last year, with the explanation that the teams needed an extra day of preparation to get the bikes set up with the Michelin tires and spec electronics.

No major technical rules are to change for 2017 (with the exception of the banning of winglets), but the extra day of rest is to be maintained.
