Suzuki Shows Off a New Turbocharged Engine in Tokyo

By 28 Comments

Suzuki is making it no small secret that it plans to get in on the forced induction game in the two-wheeled space. The Japanese manufacturer first teased us with the turbocharged Recursion concept back in 2013, at the Tokyo Motor Show.

Since then there have been rumors that the Suzuki Recursion will go into production, and just a few months ago we spotted Suzuki trademarking the Recursion name in the US and European Union.

Now at the 2015 Tokyo Motor Show, Suzuki has a turbocharged engine on display, though little to say about it.

Rumors: Ducati 1299 Streetfighter & New Engine Coming?

By 22 Comments

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

By 35 Comments

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

By 23 Comments

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

By 19 Comments

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?

By 31 Comments

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

By 6 Comments

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

By 9 Comments

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

By 15 Comments

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

By 9 Comments

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

By 20 Comments

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.
