CHP Drops Lane-Splitting Guidelines from Website

The California Highway Patrol has removed its guidelines for lane-splitting in the Golden State on the CHP website, after receiving a complaint from a Sacramento citizen. Though lane-splitting has been a long-time established practice for motorcyclists in California, the act is poorly defined and regulated. In an effort to define what it viewed as safe and prudent, the CHP released last February a list of guidelines for motorcyclists to follow while lane-splitting in the Golden State. The guidelines were not law in the de jure sense of the word, but without any other comment from a government entity, they became the de facto rules of the road, which leads us to today.

Ride Review: Energica Ego

Arriving then at Alice’s Restaurant, a local motorcycle hangout near A&R HQ, I had plenty of skepticism packed with my leathers, helmet, boots, and gloves. However, the design of the Energica Ego had begun to grow on me — it wasn’t the same lustful wanting that I had with the lines of the Mission RS though, nor the racing-bred techno-orgasm that comes with the MotoCzysz E1pc — but it was a certain appreciation that the bird-like nose no longer rubbed me the wrong way.Just as the Ego had evolved into something more refined and polished over time, so too had the company. After riding the Ego on a modest trip down one of the SF Bay Area’s favorite twisty roads, the impression was solidified — if I arrived a cynic to the bike launch, I left Alice’s as a convert.

MotoGP: Crutchlow, Dovizioso, & Iannone To Stay at Ducati Corse — Will Ride Radically New Desmosedici GP15

After all the speculation of massive changes in Ducati’s MotoGP team, all is to remain the same. During the World Ducati Week event held for fans of the Italian marque at Misano, both Andrea Dovizioso and Cal Crutchlow announced that they would be remaining with Ducati for 2015. The news means Crutchlow chose not to exercise his option to leave, and Dovizioso was persuaded to sign-on for two more years. In addition, it means that Ducati has exercised its option to extend the contract with Andrea Iannone, with Iannone to be given factory support.

The 5 Most Dangerous Motorcycles in America?

Contrary to what the AMA or motorcycling gentry may believe, not all motorcycles are created equal. Due to a combination of marketing, riding styles, and environment, the following five types of motorcycles are the country’s most dangerous. While the NHTSA doesn’t track motorcycle accidents and crashes based on the type of motorcycle being ridden (among other things), the cultural factors that surround motorcycle injuries and fatalities paint a stark picture, which we’ve shared with you here.

Moto2: Brough Superior Race Bike Will Debut at Silverstone

Despite some early promise, there has been much complaining of a lack of innovation from chassis builders in Moto2. the bikes have followed the same basic layout as all modern race bikes since the late 1980s: aluminium twin spar chassis and conventional suspension arrangements. The only real interest has come from wildcards. At Le Mans, the French Promoto Sport team raced their Transfiormer chassis, with some solid results. Beyond that, the bikes have been pretty much identikit. At Silverstone this year though, another interesting wildcard will get its first public running. The British round of Moto2 will see the Brough Superior make its debut in a competitive race, after making an appearance at the Goodwood Festival of Speed last year.

Up-Close with the Energica Ego Electric Superbike

A project from Italy’s respected engineering firm CRP Racing, I first had the opportunity to see the Energica Ego at the 2011 EICMA show. The machine wasn’t a runner at the time, as CRP was still looking for a drivetrain partner that could supplement CRP’s already extensive knowledge in chassis design. Fast-forward to the 2013 EICMA show, and the Energica sub-brand debuted its first production electric superbike, the Ego. The naming might be a bit tough, especially for us Anglophones, but this 134hp, 143 lbs•ft superbike packs a punch, and is remarkably well-refined.

She’z Racing at Suzuka — When a Plan Comes Together

We are pleased to have Shelina Moreda writing Asphalt & Rubber’s newest column, “She’z Racing at Suzuka”, which will follow her and Melissa Paris’ venture into racing at the Suzuka 4-Hour endurance race later this month. The American Duo are making the first all-female race team at the Suzuka 4-Hour, and will be campaigning a Honda CBR600RR with the Synergy Force Moriwaki Club team. We hope that you will enjoy the unique perspective that Shelina will be sharing with us. Race day is July 25th.

Bimota BB4 Concepts by Oberdan Bezzi

I had to check the last time we showed you some of Oberdan Bezzi’s work, and it was over three months ago. The Italian designer has certainly been busy since that time though, as he has produced a number of BMW/Bimota concepts for us to ponder about. Imagining the Italian company’s current trend of using BMW power plants — as has been seen with the Bimota BB3 — Bezzi’s drawings instead use BMW Motorrad’s popular boxer engine as their base. The effect is an interesting one, as the BMW’s boxer engine has proven to be the base of the German brands Top 3 selling bikes, and has found interesting applications in the BMW R nineT modular machine, and the BMW Roadster Concept motorcycle.

Sunday Summary at Sachsenring: Marquez’s Perfect Record, Dangerous Starts, & A Spaniard-Free Zone

The former England soccer player Gary Lineker once described the sport as follows: “Football is a simple game; 22 men chase a ball for 90 minutes and at the end, the Germans always win.” It feels somehow fitting to paraphrase that quote on the day that the Germans play in the World Cup final. Motorcycle racing is a simple sport, where 23 people ride a MotoGP bike as fast as they can, and Marc Marquez always wins. He found yet another way to win at the Sachsenring. A heavy rain shower between the Moto2 race and the sighting lap for MotoGP left the grid in disarray, with about three quarters of the field heading in to swap from their wet to their dry bikes at the end of the warm up lap.

2015 Kawasaki Ninja ZX-14R ABS 30th Anniversary Edition

In case you didn’t know, this is the 30th anniversary of the Ninja motorcycle line from Kawasaki. To commemorate the occasion, Big Green has already debuted the 2015 Kawasaki Ninja ZX-6R 30th Anniversary Edition and 2015 Kawasaki Ninja ZX-10R 30th Anniversary Edition motorcycles, and today the 2015 Kawasaki Ninja ZX-14R ABS 30th Anniversary Edition joins them. Like its sport bike brethren, this special ZX-14R comes with a special livery, which will be available to only 300 lucky owners (each unit is specially numbered). Finished in a “Firecracker Red” with “Metallic Graystone” paint, along with gold pinstriping and gold brake calipers, you can be certain that the changes are purely skin deep for this special model.

Honda’s Forgotten “Frameless” Chassis Design Patent

Hondas Forgotten Frameless Chassis Design Patent Honda motorcycle monocoque chassis design patent 635x508

Before Ducati’s monocoque chassis design was all the rage in superbike design, the folks at Honda were busy toying with the same idea.

Outlining a patent in 2006 for a motorcycle whose engine would be fully utilized as a part of the chassis, Honda’s design, which differs in minutiae, predates Ducati’s patent by almost a year and a half.

A noticeable departure from Honda’s MotoGP design, one can argue whether Honda’s monocoque chassis was destined for the next iteration of the CBR1000RR or the next generation VFR at the time of its conception.

Honda V4 Superbike Engine Outed in Patent Photos

Honda V4 Superbike Engine Outed in Patent Photos honda v4 engine patent drawing 635x423

Honda’s road-going V4 superbike project has seemingly stalled, for the umptenth time in the past decade. While the bike has been rumored for years, the project just a year and a half ago was confirmed by Honda CEO Takanobu Ito.

Since that confirmation, the project’s delivery time has been pushed back, thought the Japanese motorcycle manufacturer has committed itself to building the MotoGP-inspired road bike.

With reports speculating on a possible price tag well into the six-figure range, the rumormill is on the rev limiter regarding this superbike, so if there is one thing we actually know about the machine, it is that we don’t actually know much about it.

A 1,000cc displacement is of course expected, along with a four-cylinder v-angle cylinder configuration. If we can presume a setup similar to what is found on the Honda RC213V MotoGP race bike, then make that a 90° cylinder head arrangement.

If we had really been on the ball though, we likely could have told you all this, six months ahead of Ito’s confirmation, as patent documents discovered by Spanish magazine SoloMoto shows the V4 superbike engine in line-drawing form, from as early as March 2012.

More on Kawasaki’s Supercharged Motorcycle Engine

More on Kawasakis Supercharged Motorcycle Engine Kawasaki supercharged motorcycle engine patent drawings 03

The tease of 2013 has to be Kawasaki and its supercharged four-cylinder engine, which the Japanese OEM debuted at this year’s Tokyo Motor Show. Showing the engine, and giving virtually no information about the intended uses of the supercharged power plant, we have been left to speculate over what Kawasaki’s intentions are in the two-wheeled forced-induction realm.

Diving through the Google’s database of patent applications though,  we see that over the years Kawasaki has published a number of patents that relate to adding a supercharger to a motorcycle. Not only has Kawasaki been thinking about how to fit a supercharger into a motorcycle for some time now, but the OEM has some clever tricks up its sleeve in order to optimize its designs.

Erik Buell Racing Patents Hybrid Motorcycle Design

Erik Buell Racing Patents Hybrid Motorcycle Design Erik Buell Racing hybrid motorcycle patent 02 635x455

It seems Erik Buell Racing has been thinking about alternative-fuel vehicles, as the company from East Troy had filed and received a patent for a hybrid drive motorcycle design.

There is nothing particularly astonishing about EBR’s patent, after all with hybrids being all the rage in the four-wheeled world, it was obviously only a matter of time before that same trend transitioned to motorcycles as well.

However, what is interesting about Erik Buell Racing’s patent is that it doesn’t set forth the Prius-inspired setup that you would expect, where an electric motor takes over or assists an internal combustion engine.

Instead, EBR’s setup is more like the Chevy Volt, with a small petrol-fueled generator being on-board to charge the bike’s batteries once they have been depleted by the electric motor, and thus killing the range anxiety that is prevalent in current EV bike designs.

So You Want to Know How to Build a Front Wheel Regenerative Braking System on a Motorcycle?

So You Want to Know How to Build a Front Wheel Regenerative Braking System on a Motorcycle? Chip Yates KERS patent 1 635x452

Eighteen months ago, Chip Yates filed for a patent on his front-end KERS design for motorcycles, which means that today the United States Patent and Trademarks Office (USPTO) can disclose Yates’s patent application to the public. Detailing the only front-wheel regenerative-braking system for motorcycles that we know to exist, the design built by Yates allows a motorcycle to scavenge power from the braking force applied to the front wheel of a motorcycle, and store it in an electric battery system.

Current regenerative-braking systems on the market, like the ones that help power the 2012 Zero S that we tested just a few months ago, use regenerative-braking off the rear wheel, and are more prone to locking the rear tire up if too much force is applied to the system. With 70% or more of a bike’s potential braking force coming from the front wheel, a front-end KERS system has a substantially greater ability to put power back into an electric motorcycle’s battery pack, thus either increasing the range of an electric motorcycle or allowing more electric power to be used over the same distance.

Who Wore It Best? Del Rosario Calls Out the AGV PistaGP

Who Wore It Best? Del Rosario Calls Out the AGV PistaGP Del Rosario vs AGV PistaGP 635x423

While we are excited and anxiously awaiting the AGV PistaGP helmet, one American helmet manufacturer is less-than-thrilled with the Italian company’s latest offering: Del Rosario. A small boutique firm based out of New York, Del Rosario’s aim was to bring to market helmet designs that were “caught up to the rest of the industry.” Showing off a number of CAD renders since its inception, Del Rosario has clearly missed its late-2011 shipping date, and as far as we can tell, has not actually produced any physical prototypes or finished models.

Getting a fair bit of press and then falling off the radar, Del Rosario is back in the limelight as the company sent a worded warning to AGV through its corporate Facebook page. According to a message posted by Del Rosario on its social media portal, one of the company’s former advisors showed AGV Del Rosario’s stylebook, and now three years later the PistaGP has emerged with a shell design that has some obviously similar characteristics to Del Rosario’s renders.

There Are No Sacred Cows: Harley-Davidson Patents Cylinder Head Cooling System

There Are No Sacred Cows: Harley Davidson Patents Cylinder Head Cooling System Harley Davison water cooled cylinder patent 1 635x520

The rumors that Harley-Davidson has been eying a liquid-cooled motor design have always been in abundance, and 10 years ago we saw the company test the waters of that pool with the Porsche-engineered lump that was found in the V-Rod. While the VRSC line may not have been as big of a success compared to the other models in Harley’s line-up, the water-cooled bastard child of Milwaukee still seems to sell in the tens of thousands each year, even after nearly a decade of only cosmetic revisions.

Faced with an aging demographic, an uninspired motorcycle line-up, and 21 takes on the same motorcycle design, there’s a push internally at Harley-Davidson to break-out and find a new way to engage riders, especially younger riders. The core ethos of change seems to start at the motor itself, and Harley-Davidson has already done the rounds at various electric motorcycle and drivetrain companies. There also exists amount of external and internal pressure over Harley’s pervasive use of air-cooled motors, and now whispers of a water-cooled v-twin power plant have gotten louder in Milwaukee. With those rumors now reaching a boiling point (see what I did there?), Harley-Davidson has patented a very clever way of adding liquid-cooling to its iconic v-twin motor design.

Can-Am Files for Leaning Spyder Patent

Can Am Files for Leaning Spyder Patent can am spyder leaning patent application 635x496

Bombardier has been busy over the past two years, presumably working on something new for the Can-Am Spyder. While not exactly a new idea, the Canadian company has devised a control system for a leaning vehicle…a three-wheeled vehicle shaped like a Spyder according to the patent application that was filed in in July 2009, and published this January (yes, it really takes the USPTO that long just to publish an application, let alone grant a patent). While the technical drawings have little bearing on the final product, it would at least seem logical to conclude that we can expect a leaning Can-Am Spyder in the near future.

For now this technology is just in the application process, and Bombardier hasn’t received a patent from the US Patent and Trademark Office yet. Likely unable to get past the prior art for other leaning trike designs as a whole, Bombardier’s patent focuses on the linkage for the steering mechanism, and how to overcome some of the deficiencies in current designs. Diving into the claims of the patent, Bombardier actually has a pretty clever way of having the Spyder’s frame lean and not lean under the right circumstances, which should make for a more refined three-wheeled leaning chassis.

Buell Swingarm Exhaust: Still Owned by Harley-Davidson

Buell Swingarm Exhaust: Still Owned by Harley Davidson Buell exhaust swingarm patent 635x535

Math can be tough sometimes, especially when it comes to counting, so we can understand the confusion surrounding the news that Erik Buell has recently been awarded a patent for a design that incorporates a motorcycle exhaust system inside the swingarm of the bike (now that’s some engineering). However we have the unpleasant responsibility of saying that this patent is not in fact owned by Erik Buell and Erik Buell Racing, as the filing date and patent assignee information were clearly over-looked by early reports on Buell’s patent.

While the patent was published on October 28, 2010, its was filed by Buell last year (April 24, 2010), well before Harley-Davidson closed the company, and while Erik Buell still worked as a Harley-Davidson employee. As such, the patent is assigned to the Buell Motorcycle Company, whose intellectual property is still owned by Harley-Davidson.

Dual Clutch Honda CBR1000RR in the Works? Honda dual clutch transmission cut away 635x423

Visordown is reporting that Honda has filed patents in Japan that would allow the motorcycle manufacturer to port their dual-clutch transmission, a la VFR1200F, over to multiple platforms in the Honda line, including the Honda CBR1000RR. The patents reportedly center-around reducing the cost to implement the DCT into other motorcycle models by simplifying the electronics and sensors that go into the transmission, and removing expensive components of the existing DCT transmission.
