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.

Motus-Motorcycles-MST-R-LCD-dash-02

This weekend at MotoGP’s Red Bull US Grand Prix at Laguna Seca, I stopped by the Motus ten to give Lee Conn and Brian Case some grief, and to see how the production-ready Motus MST was looking. The bikes looked similar to their prototype form from two year’s ago, with obviously more fit-and-finish in the overall design. One of the big changes I noticed though was that Motus has dropped the industry standard analog tach and LCD speedo for an all-glass cockpit design.

It was two years ago that I first caught glimpse of the Motus MST at Laguna Seca (actually, I missed seeing the prototype machine at the track, and had to ambush the Motus crew at Alice’s Restaurant the next day), but now the American motorcycle upstart is ready to debut its production sport-tourer.

Motus V4 Baby Block Gets $10,220 Price Tag

01/28/2013 @ 2:22 pm, by Jensen Beeler15 COMMENTS

Motus-KMV4-motor-exploded

When American motorcycle upstart Motus Motorcycles first began its undertaking of the Motus MST sport-tourer, the company from Alabama made it clear that its 1,650cc engine would be the centerpiece of the bike’s design. Hoping to build off the tuner culture that developed around push-rod engines in the automotive world, Motus even went as far to say that the Katech-designed KMV4 engine (now without GDI) would be made available as a crate motor for hobbyists.

With the Motus MST nearly ready for public consumption, the American company is making good on its other promise, and has released pricing on its “baby block” engine. At a cool $10,220 of your hard-earned cash, the turnkey 165+ hp V4 motor can be yours (along with the engine’s ECU, ride-by-wire intake, engine harness, and fuse box). A pricy sum for the small peppy engine, pricing on the Motus Baby Block at least puts the $30,000+ price tag of the Motus MST in perspective.

It is a rarity that an A&R reader is better informed than us on a topic, but one of the great things about online media is that there is an instantaneous two-way dialogue on every subject we publish. As such, a special hat-tip goes out to commenter “Bob” who spilled the beans that Motus had dropped gasoline direct injection (GDI) for the Motus MST sport-tourer that the company is soon to unveil at the Daytona Bike Week. We followed up the comment with Lee Conn, President and Co-Founder of Motus, about the comment, where he confirmed that Motus would adopt a port fuel injection & ride-by-wire scheme instead of the heavily touted GDI setup.

“Having ridden the MST’s with GDI all over America, I can report that we pioneered a really cool GDI system and it works great,” said Lee Conn. “GDI is a modern, smart and efficient way to fuel an engine, but after a lot of discussions with dealers, customers, technicians, and tuners, we concluded that there is not enough support in the current industry to roll out this technology yet.” After seeing what bikes A&R commenters were using in comparison to the Motus MST, Lee made a joke about how the Motus team would have to rethink its product messaging, and then said something that is very central to the Motus MST ethos.

The last time Motus Motorcycles graced the pages of A&R it was August 10th of last year — yes, I actually went back thru the pages to check that date. Since that time, the American motorcycle startup has been busy getting its sport-tourer finalized and ready for production. Launching the Motus MST prototype at the 2011 Daytona Bike Week, Motus Motorcycles will be returning to the Floridian biking event this year to announce its production plans, pricing, and availability of its American made motorcycle.

While we’ll have to wait to hear from Motus for its official plans, we expect to hear something along the line of a production run of under 300 units, with pricing in the $30,000+ range. Certainly exclusive, it remains to be seen if Motus can sell such an expensive sport-tourer without the gadgets and gizmos that normally accompany that market segment. Featuring the gasoline direct injection (GDI) 1,645cc KMV4 engine, the Motus MST will make over 160 hp from the power plant, which is also being sold as a crate motor.

Watch the Motus MST Go Around Barber Motorsports Park

04/26/2011 @ 12:48 am, by Jensen Beeler6 COMMENTS

Another update from those southern boys at Motus, this time showing off their MST & MST-R American sport-tourers hitting some track time at Barber Motorsports Park. Obviously still in the development phase of their production process, we see that the MST-R has gotten some carbon fiber clothes (yum!), while the MST looks very fit and polished with its touring bags on-board.

We’re still not sure about how the Motus MST and MST-R will fare in free market, as we’ve seen so many American motorcycle companies generate a lot of buzz with little substance. However, one thing is for certain about the Motus project: the company has the right amount of cowbell in that KMV4 1,645cc GDI motor that should make any motorcyclist with a pulse grin ear-to-ear. Check the video out after the jump…yes, it’s ok to watch it several times.

Motus Motorcycles has just released the second part of its Daytona launch video, which unlike the first version, is chalked full of close-up and detail shots of the Motus MST and the performance-packed Motus MST-R. The Daytona Bike Week was the public launch of the new American-made sport-tourer, which features the KMV4 1,645cc V4 pushrod motor with gasoline direct injection. Motus’s approach with the KMV4 is to take a page out of America’s rich hot-rodding tradition, and therefore has built a power plant that tuners and hobbiests should find the designs of familiar.

Helping Motus build this tiny buy powerful engine is Pratt & Miller Engineering, who have made a name for themselves building all sorts of racing engines, including those from the C6R Corvette Racing squad, which coincidently also uses a pushrod design. This has lead to many calling the KMV4 as simply half a Corvette motor, which the math doesn’t really support, but the philosophy surely does.

Next for the Motus crew is a ride around the United States that will not only serve as an R&D/proving method for the new bikes, but will also help drum-up interested buyers and the much needed dealers to get the motorcycle company launched off the ground. We’re looking forward to seeing the 161hp sport-tourer come to San Francisco, we just hope the rumors we’ve been hearing of a $30,000+ price tag aren’t true. Get ready to bust out your “V4” gang signs, as the video is after the jump.

Video: The Motus KMV4 GDI Engine

07/02/2010 @ 10:52 am, by Jensen Beeler14 COMMENTS

Motorcycle upstart Motus Motorcycles continues to press forward with its MST-01 sport-tourer, and has released a video that talks more about the development of their 1645cc gasoline direct-injection V4 motor: the KVM4. Balking at the advice of others not to build their own powerplant, Motus has teamed up with Katech to design an in-house motor for the Motus MST-01.

Motus Motorcycles has trickled out a bit more information about its Made in America MST-01 sport-tourer, giving CycleWorld their obligatory first look. What do they have to report? A 1650cc V4 motor with two valves per cylinder that features direct injection, which sums up to equal 140hp. More on that and photos after the jump.

Motus Motorcycles is back on the radar after their mysterious awakening back in April. Along with slightly less cryptic information about their MST V4 sport-tourer, Motus has announced their partnership with Pratt & Miller.

If you’re not familiar with Pratt & Miller, they’ve made quite a name for themselves in the automotive endurance racing scene developing chassis in the American Le Mans Series, Rolex Grand-Am series, NASCAR, and have won the 24 hours of Le Mans six times in the GT1 category. Pratt & Miller have also worked with the US military in developing missiles and other classified projects.
