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.

spirit-motorcycles-gp-sport-street-corse-r-02

If you are having a hard time figuring out what to get that special motorcyclist in your life, let us suggest something from the recently formed Spirit Motorcycles brand.

The British marque’s first offering is a trio of motorcycles: the GP Street is a naked street bike, the GP Sport is its fully faired sibling, and the GP Corse R is the full-fledge track supersport machine.

The base model machines make 160hp from their three-cylinder engine, and tip the scales around the 320 lbs mark. But, if you want to spring for the R-spec models, you are looking at a 180hp and 309 lbs machine, sans fuel. Do we have your attention now?

To power their machines, Spirit is using a repurposed Triumph Daytona 675 engine, which has been boosted to 750cc by stroking out the triple. Engine compression has been modified to help boost power, as well.

Like many things on the Spirit lineup, the chassis is of note, as the chrom-moly steel tubes have been brazed-welded together, for added flex. Spirit says that the chassis steering angle, rake, and trail is fully adjustable. The swingarm is made from cast aluminum, and the fairings are carbon fiber.

2017 Honda CRF450 Supermoto, for France Only

11/30/2016 @ 10:27 am, by Jensen Beeler35 COMMENTS

2017-honda-crf450rx-supermoto-france-09

America might have invented supermoto racing, but the sport’s largest support base easily comes now from that other side of the Atlantic – more specifically, from France.

So, it shouldn’t surprise us to learn that Honda’s French importer Superboost makes a special supermoto version of the Honda CRF450 for the French market.

For the 2017 model year, the Honda CRF450 Supermoto follows that changes made to Big Red’s 450cc dirt bike, which notably includes the return of fork springs (goodbye air forks), an electric starter, and down-draft fuel injection.

Basically a kit that is added at the importer level, the 2017 Honda CRF450 Supermoto lineup has three models, building off the CRF450R (€11,299), CRF450RX (€10,999), and CRF450X dirt bike (€10,999), with each getting their own taste of the supermoto treatment.

For American readers, don’t expect to see these supermoto models at your local dealership, as this is strictly a project undertaken by the Frenchies.

Though, it would be nice to see American Honda supporting the local supermoto scene, and offering some sort of motard kit for its venerable CRF450. The Swedes and the Austrians shouldn’t have all the fun.

Two Enthusiasts Podcast #39 – Live in PDX

11/30/2016 @ 12:25 am, by Jensen Beeler15 COMMENTS

two-enthusiasts-podcast

Episode 39 of the Two Enthusiasts Podcast is a celebration of one year of motorcycle podcasting, and to celebrate our birthday, we figured we should do a live show in our hometown of Portland, Oregon.

The good folks at MotoCorsa were kind enough to host the 40 brave souls that braved the PNW weather to listen to Quentin and myself blather about motorcycles.

It was good fun, and we covered topics like the recent MotoGP test in Valencia, the business issues that comes with running a race track, and how “race” ABS works and how it’s evolving.

We finish the show with a Q&A session from the audience, with questions about racing, race tracks, new bikes, and how to pronounce Spanish words being the topics of choice.

We are extremely grateful for the turnout at our first live show, and hope to bring the format to other cities in the coming months. We are also thankful for all our listeners who couldn’t make it to Portland, but continue to listen to the show each week. Hopefully, we can meet you all soon.

Until then, you can listen to the show via the embedded SoundCloud player, after the jump, or you can find the show on iTunes (please leave a review) or this RSS feed. Be sure to follow us on Facebook and Twitter as well. Enjoy the show!

Just like Steve Martin’s 1977 album, one of the main themes of this years’s International Motorcycle Show in Long Beach was “let’s get small”.

Almost every major manufacturer unveiled a bike in the 300cc category. BMW showed off its G310R standard and G310GS dual sport, Honda showed its CRF250L Rally, Suzuki introduced its GSX-250R, and Kawasaki unveiled its Versys-X 300.

Additionally, Honda had its world introduction of the 300 and 500 Rebels. It’s definitely a good time to be shopping for smaller motorcycles!

No Mandatory Noises for Electric Motorcycles, Yet…

11/28/2016 @ 11:22 am, by Jensen Beeler22 COMMENTS

alta-motors-exhaust-photoshop

In a world with increasingly stringent emission and noise standards, vehicle OEMs are continuously tasked with making their automobiles and motorcycles quieter.

Such regulations have brought us some ridiculous creations in the motorcycle realm, especially for the Japanese and European market, but changes are afoot here in the United States as well.

Today, we bring you such news, but it’s probably not the news that you think. The National Highway Traffic Safety Administration (NHTSA) has just set a standard that will see electric automobiles getting louder, instead of quieter, in the name of vehicle safety.

But oddly enough, the new rule does not apply to electric motorcycles…for now.

In a typically robust column written at the end of last week, David Miller, editor of Bikesportnews.com, suggested that the time that double World Superbike champion Jonathan Rea had set on Thursday at the combined WorldSBK and MotoGP test at Jerez had made the MotoGP bikes look a bit silly.

Rea had ended the day as the fastest rider on the day, setting a time of 1’38.721, nearly a quarter of a second faster than Alvaro Bautista, who was riding the Ducati Desmosedici GP16 at the track.

Rea had set the time on a modified version of a road bike, costing something in the region of €300,000, beating the satellite Ducatis (estimated lease price, just shy of €2 million), satellite Hondas (official lease price €2 million, actual cost to lease about 50% higher than that), and the factory Suzuki, KTM and Desmosedici GP17 (“I’m sorry sir, you’ll have to put your checkbook away, this one isn’t for sale”).

Miller draws a number of conclusions from this, some sound, some based more on hyperbole than reality.

The return of Marco Melandri to World Superbike in 2017 has been one of the biggest talking points in the series over the last few months. The Italian has won 19 races, from 100 starts, in the championship, and as a former 250GP World Champion, and 22-times Grand Prix winner, his credentials are highly impressive.

The last two years have been a blot on the copybook, however. Having enjoyed an exceptionally strong finish to the 2014 WorldSBK season, Melandri looked well placed to finally win a second world title.

Winning six races and finishing fourth in the standings looked to be a perfect springboard for a title run the following year, but Aprilia had other ideas and with Melandri, and the Italian was forced to race in MotoGP. The relationship then turned sour.

It is hard to think how Kawasaki could make the Ninja H2 more modern, considering the bike’s supercharged engine, radical aerodynamics, and plethora of electronics. But, that didn’t stop the minds at Divergent 3D, a company that is specializing on making vehicles with 3D printing technology.

We have talked about 3D printing here at Asphalt & Rubber before, a technology that when the economies of scale finally take hold of it, should turn several industries on their heads.

For the Divergent 3D Dagger, you can see that the frame, swingarm, and fuel tank are built using Divergent’s 3D printing technology, which uses additive manufacturing to create metal-alloy nodes, and carbon fiber tubes to connect them, when applicable.

In the case of the Divergent 3D Dagger, our best information is that the machine’s chassis comprises solely of metals that have been 3D printed, sans the carbon fiber tubes that can be found on the company’s Blade supercar, though it wouldn’t be hard to change the design of the frame to employ carbon fiber.

2017-world-superbike-logo

The provisional 2017 World Superbike calendar has been released, but unlike the MotoGP calendar, which is unchanged, there are a couple of minor differences to the schedule.

The World Superbike class will contest 13 rounds, just as they did in 2016, spread across three continents. Sepang and Jerez have been dropped, and Portimao makes a comeback.

The WorldSBK calendar also sees a new class added to the series. As announced previously, the new World Supersport 300 class has been added as a cheap entry series, where young riders will take each other on aboard a wide range of the cheap, one and two cylinder sports bikes which manufacturers are currently building.

Three Rider Opinions on MotoGP vs. WorldSBK

With MotoGP and WorldSBK sharing the track at Jerez on Wednesday, Jonathan Rea surprised the paddock by leading the way for most of the day. So, Asphalt & Rubber sought out three opinions on the differences between the MotoGP and WorldSBK bikes, from the riders who have ridden both. -JB

As the sun set on the third day of the Jerez Test, Jonathan Rea hogged the limelight with the second fastest time of the day. With MotoGP bikes sharing the track with World Superbike runners, the story of the day was that Rea spent most of the day leading the “faster” GP boys. 

The question in the aftermath however was how does this reflect on both championships?
