It’s hard to fault the current Aprilia Tuono V4 R APRC ABS, except perhaps the sport bike’s alphabet soup name, which the Italian company seems to grow longer with each passing year and added feature.

That being said, the Tuono V4 R is easily our pick for the best streetfighter on the market — it packs a punch with its V4 engine, has the industry’s best electronics package, and is just downright fun to ride.

Noale, Italy isn’t resting on those laurels though, so accordingly the 2015 Aprilia Tuono V4 R APRC ABS is getting some minor updates: namely a bump in peak power (170hp) and torque (83.3 lbs•ft), thanks to a new exhaust system.

When the Erik Buell Racing 1190SX first debuted, EBR was tight-lipped on any specifics about its streetfighter model. Thankfully East Troy has given us a few more details, and we now know that the 2015 Erik Buell Racing 1190SX will not have a detuned v-twin motor from its EBR 1190RX superbike counterpart, so 185hp and 101 lbs•ft of torque will be on tap for street bike fans…as it should be

Additionally, the EBR 1190SX will come with a $16,995 price tag, which prices it just above the Aprilia Tuono V4 R APRC ABS ($14,999) and BMW S1000R ($13,150 – $14,950), while being on par in price with the KTM 1290 Super Duke R ($16,999).

Thanks to our network of Bothan spy tipsters, we posted today the still-unreleased photos of the Harley-Davidson Project Livewire. Details were light from our sources though, but Bothans are a tireless breed (note: for new readers, we sort of have this whole Star Wars motif on leaked stories…just roll with it, we already know we’re nerds).

While the consensus on Project Livewire seems to be that it’s a looker, the devil is in the details…and now we have those as well. Featuring a three-phase induction motor with 55 kW of power (just under 74hp) and 52 lbs•ft of torque, the Harley-Davidson Livewire is packing more power than both the Brammo Empulse R (54 hp) and Zero SR (67 hp). That’s the good.

The bad is that despite its hefty casing size, the Harley-Davidson Livewire motorcycle is a little light in the loafers when it comes to battery capacity. Our guesstimate on battery pack size, judging from Harley’s quoted charge time and parameters, is somewhere in the neighborhood of 7 kWh nominal, a bit less than the 9.3 kWh and 10.0 kWh of the Brammo and Zero.

That means the Harley-Davidson Livewire is good for just over 50 miles of mixed city and highway riding that is limited to 92 mph (we’re not really sure how Harley-Davidson came up with that figure). Expect to go 0-60 in around 4 seconds.

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.

Jorge Lorenzo has won the last two MotoGP rounds in utterly dominating style. Though his win at Mugello was by a greater margin, the victory at Barcelona was one of the most impressive of his career. Afterwards, both Lorenzo’s team manager Wilco Zeelenberg and Monster Tech 3 rider Cal Crutchlow said of the Barcelona win that it was probably one of the best races he had ever ridden. Lorenzo had made only one mistake, the Spaniard said afterwards, and it was so small it did not even show up on the data.

As he had done at Mugello, Lorenzo ensured that he won the drag race to the first corner, aggressively outbraking Dani Pedrosa to take the lead. From that point, he held the Honda’s at bay until Dani Pedrosa finally broke, the Yamaha man going on to win by nearly two seconds. It was the second race in a row which Lorenzo had led from the start and gone on to win the race.

In fact, all three of Lorenzo’s wins, at Qatar, Mugello and Barcelona, have come in the same manner: Get into the first corner in the lead, push hard in the early laps, and ride as perfectly, and as fast, as possible throughout the entire race. There is simply no one else in the world capable of riding a motorcycle for 25 laps at full speed as well as Jorge Lorenzo at the moment.

As impressive as Lorenzo’s wins have been, the one thing they have lacked is spectacle. There has been no drama, no battles, no need to defend, and the only place Lorenzo has needed to attack has been off the line, an area perhaps aided by the new clutch Yamaha have been using for this year.

Does Lorenzo not enjoy the battle, is he incapable of holding his own in a battle, or is it down to the bike? It is a question which is debated by fans around the world, with an answer apparently hard to give.

After debuting the 2012 Kawasaki ZX-14R / 2012 Kawasaki ZZR1400, Team Green has been fairly tight-lipped about quoting specific performance figures on the company’s revamped hyperbike. Carefully gleaning the performance specifications from its US and UK websites, it looks like Kawasaki Motors Europe has spilled the beans on the ZX-14R’s horsepower figures. Perhaps letting down those who expected the ZX-14R/ZZR1400 to break the 200+ horsepower barrier, Kawasaki’s site quotes power figures just shy of 200hp.

Ducati has released pricing and power specs for the 2012 Ducati Streetfighter 848 here in the US, and the fighter’d version of the Superbike 848 is interestingly priced at $12,995 MSRP, the same price as the Superbike 848 EVO “Dark” or $1,000 less than the colored Superbike 848 EVOs, which retail for $13,995. Making 8hp less than the current Superbike 848 EVO, the Ducati Streetfighter 848’s motor makes 132hp and 69 lbs•ft of torque on Ducati’s dynos, just 23hp shy of the current Streetfighter 1098. Additionally, the Ducati Streetfighter 848 will tip the scales at 373 lbs dry (439 lbs wet), the same weight figure quoted for the current Ducati Streetfighter 1098.

As we stated when the Ducati Streetfighter 848 first broke cover, the positioning on the smaller Streetfighter was going to be critical and difficult for Ducati. The Bologna brand not only has to balance the the Streetfighter 848 against the Superbike 848 EVO, but also against the Monster 1100 EVO as well, which retails for $11,995. With the Streetfighter 848 getting lower-spec suspension and brakes compared to the Superbike 848 EVO (along with a presumably smaller airbox resulting in less power), Ducati seems to be hoping that the standard traction control on the SF848 will help distinguish the Streetfighter from its Superbike compatriot, which has no Ducati Traction Control (DTC) option.

Confirming what we reported back in November of last year regarding the performance figures for Ducati’s new Superbike, Ducati dealership Pro-Italia posted on its Facebook wall (now redacted) a less-than-cryptic “395/195” message while in attendance at the Ducati Dealership meeting in Miami, Floria. Noting the wet weight and brake horsepower, the new 2012 Ducati 1199 Panigale makes good on its promise to trump its predecessor by over 20hp and 20 lbs. To thank for the these benchmark miracles is the 1199 Panigale’s very over-square Superquadrata motor (also known as the SuperQuadro in some rumor reports), which will rev higher than any other previous Ducati Superbike motor to-date, and the company’s new “frameless” chassis design, which has been floundering in MotoGP.

While we can’t speak for the efficacy of Ducati’s new chassis philosophy, and how it will work on the company’s new v-twin production bike, the spec-sheet racers should be impressed with this latest piece of information. And as if those figures weren’t impressive enough already, Asphalt & Rubber has learned that the Ducati 1199 Panigale homologation special, the made-for-racing “production” model which has been making its appearance in the bulk of the 1199’s spy shots, has been producing over 205hp at the crank during its recent testing at Borgo Panigale facility (the namesake for the 1199 Superbike), while in its “stock” form. While we don’t know what naming convention Ducati will use on the race-bike-with-lights-on-it 1199, A&R does know that it will not receive “R” nomenclature that we’ve seen in the past.

The news of the 2011 Aprilia RSV4 R APRC got me thinking today about where the sport bike market is headed from a big picture perspective.

The sport bike market has been dominated the constant need to develop motorcycles with more power, less weight, and new performance enhancing technologies, and you’d be hard pressed to find a year where the bike with the most horsepower wasn’t the top-seller in this category (case in point: the complete sales domination of the BMW S1000RR during 2010).

For years the motorcycle manufacturers, especially the Japanese, have been painting themselves into a corner by constantly having to one-up each other with horsepower figures in order to sell motorcycles in this segment.

With bikes like the 2011 Kawasaki Ninja ZX-10R approaching the 200hp barrier, the question about “how much power is enough?” has been cropping up, and it certainly could be that we’re approaching the point in time where the relevancy of this metric is losing it’s power (pun moderately intended).

So what will be the new kingmaker for sport bikes? The electronics package.

We just got off the phone with Kawasaki HQ, and it’s official: the 2011 Kawasaki ZX-10R will inadvertently get a power decrease when it comes to the United States because of the EPA’s regulation of noise pollution, confirming earlier rumors from this week. The issue surrounds the EPA’s new methodology for measuring exhaust noise levels, which now involves taking the measurement at a percentage of the total rev range, instead of a specific rpm value.

The result is that the 2011 Kawasaki ZX-10R passes the Euro III standards, but fails the EPA standards in its unadulterated form. To come into compliance with the EPA’s Noise Control Act, Kawasaki has lowered the rev-limit on the 2011 Kawasaki ZX-10R by 750 rpm in order to meet the new criteria. The byproduct of lowering the rev-limiter will reduce the new ZX-10R’s maximum power output, but Kawasaki isn’t saying by how much.

Immediately after the launch of the 2011 Kawasaki ZX-10R, which claimed a 207hp figure at the crank with ram-air (197hp sans the air), rumors began to swell that the new ZX-10R’s peak performance figure would be drastically less in the American market. Apparently and supposedly due to federal regulations by the EPA, Kawasaki will be lowering the rev-limiter on the 2011 Kawasaki ZX-10R in order to comply with US government provisions.

Whether those rumors are in regards to the ZX-10R’s emissions or noise levels at that rev range is unclear at this time, but speculation that the power decrease is due to the new 10R’s peak power figure being north of 200hp are completely unfounded (Editor’s note: the United States has no provisions, at both the state and federal level, that cap motorcycle horsepower performance levels from the factory). We’ve reached out to Kawasaki for an official response on the issue, more as we get it.
