2015 Suzuka 8-Hour Endurance Race Results

In Japan, the Suzuka 8-Hour is a huge deal, but for the rest of the world, it ranks on par with the rest of the FIM Endurance World Championship. That’s kind of a shame, really, as the Endurance World Championship is the only motorcycle championship where we still see different tire manufacturers competing against each other, the bikes are beautifully technical in their own special way, and in the case of Suzuka, there are often heavy-hitters at play. This year was no different, with Yamaha fielding its “Yamaha Factory Racing Team” with two MotoGP stars, Pol Espargaro and Bradley Smith, along with factory test rider and MotoGP podium-finisher Katsuaki Nakasuga.

Recall: KTM 1290 Super Duke R

Attention 2014 KTM 1290 Super Duke R owner, KTM North America is recalling 640 units of “The Beast” for a fuel leak that may occur from the threaded inserts at the rear of the gas tank. Obviously, a fuel tank poses a safety hazard to the rider, not only for its propensity to combust, but its ability to degrade traction to the rear tire. As such, KTM will notify affected owners, and KTM dealers will seal the threaded inserts to prevent future fuel leaks. If the motorcycle shows evidence of an existing fuel leak at the threaded insert, the gas tank will be replaced. Of course, these repairs will be performed free of charge. The recall on the KTM 1290 Super Duke R is expected to begin in August 2015.

Erik Buell Racing Acquired by the Flying Spaghetti Monster

Social media and some assorted motorcycle news websites (first here, and now here) are feverishly reporting that Erik Buell Racing has been out-right acquired by Hero MotoCorp, during the company’s receivership auction, thus confirming the wet-dream conspiracy theories of Buellistas around the world. The report was first started by the stalwart news source Motorcycle.in.th, and was then elevated quickly into the realm of semi-truthfulness by a bevy of other news outlets. With the journalistic bar now set so low, Asphalt & Rubber feels comfortable reporting that there is indeed a new owner for Erik Buell Racing, but it is not Hero MotoCorp, but instead the Flying Spaghetti Monster — deity to the Church of the Flying Spaghetti Monster.

Official Details & Photos of the 2016 Honda Africa Twin

Honda has officially dropped details and photos on its highly anticipated adventure-tourer, the 2016 Honda Africa Twin. A continuation of the legacy by the same name, the new Honda Africa Twin is an off-road focused machine that will go head-to-head with the big ADV bikes already on the market. Built around a 998cc parallel-twin engine, which makes 94hp and 72 lbs•ft of torque, the Africa Twin tips the scales at the curb at 503 lbs (standard model, first photos after the jump) / 534 lbs (DCT/ABS models, shown above). What we think ADV riders will come around to is Honda’s off-road built dual-clutch transmission, which will have the benefit of making shifts while out of the saddle much easier, and giving clutch-free operation, much like a Rekluse clutch.

Gear Review: Arai Corsair-X Helmet

When it comes to helmet brands, Arai Helmet is perhaps one of the best known in the business; and when it comes to the Japanese company’s flagship model, the track-focused Corsair reigns supreme. So, it’s a big deal when Arai decides to update its ready-to-race helmet offering, creating the Arai Corsair-X in the process. This week, we got to test the new Corsair-X in the flesh, spending a full-day riding at Thunderhill Raceway in Willows, California on Monday — melting away in the 104°F heat — as well as riding around my new hometown of Portland, Oregon. So let’s cut the fluff, breakdown what’s new with the Corsair-X, and talk about what our impressions are of this top-of-the-line helmet.

Honda Africa Twin Specs Leaked with Hi-Res Photo

Last night we brought you a leaked video of the new Honda Africa Twin, which revealed the off-road oriented adventure bike in all its glory. Today, we get to see the leaked specs of the Honda CRF1000L (the model designation of the Africa Twin), along with what looks like an official high-resolution photo. The spec-sheet for the Africa Twin has long been something of interest for ADV fans, with the obvious questions being 1) how much horsepower will it make? and 2) how much will it weight. The answers are 94hp, and 458 lbs dry (467 lbs with ABS, 489 lbs with DCT).

Finally, Here is the Honda Africa Twin in All Its Glory

Honda has been teasing a six-part video series about the Honda Africa Twin, and the final installment has just leaked onto the internet. As you would expect, the video finally gives us the full monty on what the Honda CRF1000L will look like, along with some great action footage. Perhaps even better, the final installment of Honda’s video series also features a very interesting discussion with HRC riders, Honda engineers, and stakeholders to the Africa Twin brand. The discussion is very insightful to the development of the 1,000cc adventure bike platform, including off-roading’s first dual-clutch transmission (DCT).

New Kawasaki Ninja ZX-10R Coming for 2016

Superbike fans should rejoice to the news that Kawasaki has an all-new ZX-10R in the works for the upcoming model year. The news comes from Germany’s reliable Speedweek publication, which interviewed Guim Roda, the Team Manager of Kawasaki’s World Superbike racing effort. Talking to Speedwekk, Roda said “we will have a new Kawasaki ZX-10R in 2016. The concept will be the same but, with some details and changes, it will be even more competitive. Given that the current rules are very restricted, the motorbikes have to be developed with an eye on the sport. We are heading on a path that Aprilia, Ducati and BMW have already taken for this year by bringing out new bikes.”

SCTA Cancels Bonneville Speed Week, Again

Bad news continues from the Bonneville Salt Flats, as the SCTA has officially cancelled its upcoming Speed Week event — an event that was cancelled last year as well. As we reported earlier, Speed Week was put into serious doubt because of the conditions of the salt flats, which were shown to have a thin salt layer and wet/muddy conditions that made the historic site unsuitable for land speed racing. Spending Tuesday morning at Bonneville looking for a suitable stretch of salt for a 2.25-mile course, SCTA President/Race Director Bill Lattin & the BNI Chairman Roy Creel deemed the conditions unsafe for a race course, and thus dashed any hopes of the event being salvaged.

Rumors: Ducati 1299 Streetfighter & New Engine Coming?

If you believe everything you read on the internet, then surely you know that Ducati is allegedly getting ready to release a Panigale-based Streetfighter in the next few months. Another potent rumor making the rounds is that Ducati is working on a totally new v-twin engine, which will meet Euro 4 emission standards. The first rumor got its start from Visordown, which says that it has received an invitation for press launch in September that will consist of “a track test for a road bike.” The second rumor comes from Moto-Station, with the French site getting word from a source that Ducati has an all-new Euro 4 compliant engine that it will debut at EICMA this November. They go on to speculate that the engine could have Ducati Variable Timing (DVT), and would fit a sport-touring bike.

Rumors: Ducati 1299 Streetfighter & New Engine Coming?

Ducati-1199-Panigale-no-fairings-01

If you believe everything you read on the internet, then surely you know that Ducati is allegedly getting ready to release a Panigale-based Streetfighter in the next few months. Another potent rumor making the rounds is that Ducati is working on a totally new v-twin engine, which will meet Euro 4 emission standards.

The first rumor got its start from Visordown, which says that it has received an invitation for press launch in September that will consist of “a track test for a road bike.”

The British publication deduces that the new model must be a sport-oriented machine to warrant the track time for journalists, and the only model in Ducati’s lineup that’s long-in-the-tooth that fits the bill is the Streetfighter 848, and the recently discontinued Streetfighter 1098.

The second rumor comes from Moto-Station, with the French site getting word from a source that Ducati has an all-new Euro 4 compliant engine that it will debut at EICMA this November. They go on to speculate that the engine could have Ducati Variable Timing (DVT), and would fit a sport-touring bike.

Let’s examine these two rumors a bit further, in turn.

Ducati Announces DVT — Desmodromic Variable Timing

10/15/2014 @ 8:17 am, by Jensen Beeler35 COMMENTS

Ducati-testastretta-DVT-Desmodriomic-valve-timing-07

As was teased, Ducati is unveiling its “DVT” technology today, which stands for Desmodromic Variable Timing, and to showcase that technology (borrowed from Volkswagen), Ducati has produced the first motorcycle engine with variable valve timing on both the intake and exhaust camshafts.

Adapted to the now-called Ducati Testastretta DVT engine, which we reported will debut first on the new Ducati Multistrada for 2015, Ducati’s new v-twin powerplant can change the intake and exhaust timing independently, and throughout the rev range.

This means that the Ducati Testastretta DVT engine can be optimized for peak power at high rpms, while maintaing rideability and smoothness at lower rpms — not to mention keeping with emission and noise regulations throughout the rev range.

Listen to the Sound of the New Supercharged Kawasaki H2

kawasaki-supercharged-engine

Continuing to build the buzz around its newest sport bike, Kawasaki has sent us a sound clip of the new H2 motorcycle, which the company will debut at the upcoming INTERMOT show.

Team Green has been pretty tight-lipped about the Kawasaki H2, though there have been plenty of clues sprinkled around for us to suss out that it will be a sport bike with a supercharged inline-four engine.

Listening to the provided sound clip seems to confirm our notion that Kawasaki’s new supercharger system is at work.

Honda V4 Superbike Engine Outed in Patent Photos

03/12/2014 @ 2:40 pm, by Jensen Beeler19 COMMENTS

honda-v4-engine-patent-drawing

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.

Did Nissan Just Make the Ultimate Motorcycle Engine?

01/28/2014 @ 7:12 pm, by Jensen Beeler30 COMMENTS

Nissan-ZEOD-DIG-T-R-06

Nissan Motor Company is better known for its four-wheeled vehicle pursuits, so it might surprise you to see its name mentioned here on Asphalt & Rubber. To front load the answer to your most pressing question, no the Japanese marque is not getting into the two-wheeled universe.

However, Nissan has been doing some interesting work, ever since it took over the DeltaWing project. In a nutshell, the Nissan DeltaWing was a failed IndyCar replacement race car project that aimed to push the boundaries of light, aerodynamical, and efficient vehicle design.

It found new legs in the endurance racing arena though, and participated in the 2012 24 Hours of Le Mans — however it didn’t finish the iconic race, when a competitor crashed into it 75 laps into the race.

Nissan and the DeltaWing team have since parted ways collaboratively, but the Japanese car maker has clearly learned something from the process. Returning to Le Mans for the 2014 season, Nissan will field a very similar design, which it has dubbed the Nissan ZEOD RC.

A hybrid race car (Nissan hopes to complete its first lap at Le Mans solely on electric battery power), what tickles our fancy most is the 1.5 liter three-cylinder turbocharged engine, which weighs a featherlight 88 pounds. Twenty inches tall, eight inches wide, the Nissan DIG-T R engine is small, though mighty. How does 400hp grab you?

More on Kawasaki’s 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.

Kawasaki Debuts Supercharged Four-Cylinder Engine

11/20/2013 @ 1:39 pm, by Jensen Beeler9 COMMENTS

kawasaki-supercharged-engine

The start of the Tokyo Motor Show is today, if you haven’t already noticed, and it looks like the Japanese OEMs have saved their best models for the home court advantage this year, with all four of the Big Four having something special for Tokyo.

Yamaha’s big announcement of course is the nearly-ready-for-production Yamaha R25 concept, a 250cc two-cylinder sport bike that Valentino Rossi says “packs quite a punch.” The tuning fork brand also has its more fanciful concepts to show-off, chiefly the Yamaha PES1 electric street bike and the Yamaha PED1 electric dirt bike.

Suzuki is in the mix as well, with its turbocharged Recursion concept, as well as its electric monkey bike, the Extrigger concept. Both of these motorcycles look like a hoot to ride, for very different reasons of course.

Not wanting to be left out on the forced-induction warpath, Kawasaki has its own blower for the two-wheeled world. Showcasing a supercharged four-cylinder engine at its booth, Kawasaki says it developed the turbine and motor in-house, and hints that we will see this in a motorcycle model in the near future.

WSBK: FIM Confirms Cost-Cutting Rules, Adds EVO Class

08/09/2013 @ 11:21 am, by Jensen Beeler15 COMMENTS

aprilia-rsv4-factory-engine-motor-cutaway

The FIM has confirmed changes to the World Superbike Championship for the 2014 season and onward. Following in the footsteps of the MotoGP Championship, WSBK will go to an eight-engine allocation (per rider, per season), have a limited number of gear ratios, as well as price caps on brake and suspension pieces. Pretty standard fare.

More intriguing though is the announcement by the FIM that World Superbikes will have a sub-category: the EVO class. British motorbike race fans will find the term familiar but for the rest of us, the distinction is simple.

The WSBK EVO class will follow the same rules as the standard WSBK-spec machine in regards to chassis, suspension, and braking components, but will follow the FIM Superstock rules when it comes to engines and electronic systems. The press release is after the jump.

MotoGP Engine Usage at the Halfway Mark: Yamaha Struggling, Honda Dominating, & Ducati Managing

08/06/2013 @ 5:38 pm, by David Emmett9 COMMENTS

Dani-Pedrosa-MotoGP-Laguna-Seca-Jensen-Beeler-4

With the 2013 MotoGP season at its halfway mark, now is a good time to take a look back and examine the engine usage for the teams and riders.

In 2012, with the engine durability regulations in their third full season, the factories appeared to have the situation pretty much under control. The only excitement arose when something unexpected happened, such as Jorge Lorenzo have an engine lunch itself after he was taken out by Alvaro Bautista at Assen last year.

For 2013, the engine allocation was reduced from six to five engines per season. Each rider now has five engines to last the entire season, for use in all timed practice sessions during each race weekend. With three seasons already under their belt, no real drama was expected, yet that is not quite how it has turned out.

2014 Aprilia Tuono V4 R APRC ABS – Now with Bosch 9MP ABS, 167 Horsepower, & More Letters in Its Name

07/17/2013 @ 6:15 pm, by Jensen Beeler20 COMMENTS

2014-Aprilia-Tuono-V4-R-APRC-ABS-19

Now 167 hp strong, those crazy Italians in Noale are upgrading there already stout Aprilia Tuono V4 R APRC for the 2014 model year, and for bonus points are adding an ABS package along with those extra ponies on the streetfighter’s peak horsepower figure.

Integrating the Bosch 9MP dual-channel ABS package, which is mated to Brembo M432 brake calipers up-front, Aprilia has made the 2014 Aprilia Tuono V4 R  a bit more stable while braking on questionable road conditions — keeping the bike inline with its competitors.

With a bevy of changes coming to the Tuono’s 999.6cc V4 power plant to boost power, we also see that Aprilia has included its second-generation APRC electronics package to the motorcycle, making it easily the most tech-savvy machine in its category.

Other changes include also a larger fuel tank (4.9 gallons), and a new seat for better street performance and ergonomics. It’s not clear if Aprilia USA will price the 2014 Aprilia Tuono V4 R at its previous $14,999 MSRP, or will continue its aggressive pricing at $13,999, like the company has done with the 2013 models.
