Honda Africa Twin Supermoto Concept by Nicolas Petit

The Honda Africa Twin doesn’t lend itself naturally to a supermoto format, though it is one of the most capable off-road adventure bikes on the market, but you have to admit that this photoshop render by French designer Nicolas Petit is very intriguing. Maybe it’s our obvious bias towards anything supermoto that is talking, or maybe it’s that there is something to the idea of taking the Africa Twin, adding 17” wheels, and lowering it just enough that riders can actually flat-foot the machine while sitting on it. Add in some styling cues that scream “supermotard” and you have a very handsome machine that is ready to conquer anything the urban environment can throw at it. Hell, it’s probably just a scary clown costume away from a good time on a gravel road. Right??!

Brad’s Leggero by Walt Siegl

The latest creation from Walt Siegl Motorcycles, Brad’s Leggero helps fill the void left behind by the departure of the Ducati Sport Classic from the Italian company’s lineup. Speaking to those who long for simpler machines, at the core of the Leggero is an air-cooled two-valve Ducati engine, which was built and blueprinted by Bruce Meyers Performance. Helping complete the café racer look is the bullet fairing bodywork, which takes a dash of modern by being made of Kevlar. The modern touches continue, with the use Öhlins suspension and radially mounted Brembo brakes. The effect is a tastefully done café racer that not only shines with real craftsmanship, but also does post-heritage right: taking the best of design from the past, without snubbing the progress of technology in the future.

More Photos of the 2017 Yamaha YZF-R6

Loyal Asphalt & Rubber readers will know how much we like our high-resolution photos here at A&R, so we wanted to make sure you could get a good high-res look at the 2017 Yamaha YZF-R6 that debuted today at the AIMExpo in Orlando, Florida. Yamaha has left its class-leading bike mostly unchanged for the next model year, when it comes to the R6 motor and chassis, which might disappoint some. But with the addition of R1-inspired styling, traction control, ABS brakes, and better suspension pieces, we think supersport fans will be pleased with this update. With the bar now set higher in the 600cc realm, hopefully we will see other manufacturers take up the challenge, and the supersport class will have new life breathed into it. We’ll have to wait and see on that. Until then, enjoy this modest photo gallery.

2017 Yamaha YZF-R6 Gets ABS, Traction Control, & More

The wait is finally over, as the 2017 Yamaha YZF-R6 debuted today at the AIMExpo in Orlando, Florida. As expected, the new Yamaha R6 visually borrows from the recently updated R1, with a similar headlight and intake setup featuring now on both machines. On the technical side of things, the 2017 Yamaha R6 is more evolution than revolution, with the basic chassis and engine configuration staying the same. However, updates for 2017 include a revised suspension package, ABS brakes, riding modes via ride-by-wire, traction control, and an optional quickshifter. While more of a model refresh, than an all-new model, Yamaha has gone to great lengths to improve upon a machine that is already leading the supersport category.

HJC Is Coming Out with Star Wars Themed Helmets

Pardon me while I geek out, just a little bit. It looks like HJC has gotten the rights to make Star Wars themed helmets for their 2017 collection. Right now, HJC is showing two helmets, one that mimic’s Kylo Ren’s helmet in The Force Awakens, and the other that replicates Boba Fett’s iconic lid. Both of these themed helmets are based off the HJC RPHA 11 helmet, the company’s top-of-the-line helmet, which also serves as a platform for HJC’s other branded, tribute, and special edition helmets. There will also be a “Death Trooper” helmet, based on the HJC FG-17 helmet, that will debut in time to milk interest from the opening of Rogue One. It should be noted that rumors about a possible Princess Lela helmet, with side-mounted hair buns, are unfounded and possibly started by this publication.

2017 Aprilia Tuono V4 1100 Factory – Just Add Öhlins

It goes without saying that if the 2017 Aprilia Tuono V4 1100 is getting a list of updates at INTERMOT, then the same must be true for the Factory version of the potent 175hp streetfighter. This means that the 2017 Aprilia Tuono V4 1100 Factory takes the new fourth-generation APRC electronics package, Bosch-powered cornering ABS, improved combustion chamber, larger exhaust can, and adds to it the typical Factory-spec improvements like Öhlins suspension (including an Öhlins steering damper). If you haven’t ridden the Aprilia Tuono V4 1100 RR or Factory, we highly recommend it – they’re so choice. The Aprilia Tuono V4 1100 easily competes as one of our favorite motorcycles at Asphalt & Rubber.

2017 Yamaha MT-10 SP – Putting the Europeans on Notice

What you’re looking at is the 2017 Yamaha MT-10 SP, a new edition of Iwata’s crossplane-power streetfighter. Despite being just a few bolted-on parts, the Yamaha MT-10 SP is one of the more interesting machines to debut in INTERMOT today. This is because it pits the Yamaha MT-10 directly against the streetfighter offerings from the European brands – something that was already occurring with the MT-10/FZ-10, even if it was unintended. The Yamaha MT-10 SP though gives the Japanese a more proper machine to go toe-to-toe with the likes of the Super Duke R, Tuono V4 1100, and other models. To do this, Yamaha has added semi-active suspension, courtesy of Öhlins. A quickshifter has also been added, along with an assist & slipper clutch.

The Yamaha MT-09 Gets a Facelift & More for 2017

Yamaha’s MT line runs with the tagline “The Dark Side of Japan” and promises edgy and affordable street bikes for urban riders. Someone in Iwata, Japan must have thought that the current Yamaha MT-09 wasn’t quite edgy enough though, which is the only way we can explain the 2017 Yamaha MT-09, which debuted today at the INTERMOT show in Cologne, Germany. Now with a “twin-eyed” LED headlight design, the Yamaha MT-09 feels a little bit more at home when parked next to the Yamaha MT-10 / Yamaha FZ-10 streetfighter. Other changes include an assist/slipper clutch, quickshifter, new suspension, and a redesigned tail section and fender.

Honda CBR1000RR SP2 – Big Red’s New Racing Platform

The current state of the World Superbike Championship rules entirely encourage the adoption once again of “homologation specials” – production bikes whose sole purpose is to be used on the race track. While none of the manufacturers have adopted a radical approach with their homologation special designs, this year’s INTERMOT show has already seen several such machines introduced, the Kawasaki Ninja ZX-10RR, the Suzuki GSX-R1000R, and the Honda CBR1000RR SP2. For Honda, the differences between the SP and SP2 aren’t terribly radical, but they are more purposeful. The 2017 Honda CBR1000RR SP2 does come with several visual cues that are different from the CBR1000RR SP model: carbon insert panels, gold striping on the tri-color paint scheme, and the more obvious Marchesini wheels.

2017 Ducati SuperSport – The Sport Bike Returns

The Ducati SuperSport is back for the 2017 model year, bringing a street-focused sport bike into Ducati’s motorcycle lineup once again. As you would expect, the 2017 Ducati SuperSport will come in two models, the SuperSport base model and a higher-spec SuperSport S model. Both bikes use the 937cc, water-cooled, 113hp v-twin engine that’s found in the Ducati Hypermotard 939. Ducati has also used a steel trellis frame for the SuperSport, which looks very similar to the one used on the current Monster line. Obviously, the front fairing takes some cues from the Panigale superbike. Ducati’s focus is for the SuperSport to augment its street lineup with something sporty that could go on the race track, but would be more at home on twisty roads, even with a passenger on the back.

Here’s a Dyno Graph of the Ducati 1199 Superleggera

05/14/2014 @ 11:16 pm, by Jensen Beeler22 COMMENTS


If you were one of the early birds to put a deposit down on the Ducati 1199 Superleggera, chances are that your $60,000 worth of titanium and magnesium, dripping in carbon fiber we might add, is sitting at your local Ducati dealer right this very second. We don’t know how you’re maintaining your composure under these circumstances…just breathe.

And soon, we all will be reading all about the Superleggera’s stellar attributes, as the chosen few of motorcycling’s journalistic ranks are headed to Mugello to put Claudio Domenicali’s homage to engineering through its paces. That’s not in our cards just yet, so we will have to keep ourselves warm at night with some cold hard numbers. Dyno graph numbers.

The good folks at RSRacecraft have stuck a Ducati 1199 Superleggera on the shop’s Dynojet 250i chassis dyno, breaking in a Moto Corsa customer’s machine at their request, and the impressive results are above.

2011 MotoCzysz E1pc Features 200+hp Motor

05/31/2011 @ 10:05 am, by Jensen Beeler17 COMMENTS

Bikes are starting to come out of the woodwork, as the TT Zero at the Isle of Man TT gets closer and closer. Now up is the 2011 MotoCzysz E1pc that will be piloted by Michael Rutter (Mark Miller will be on a modified version of the 2010 MotoCzysz E1pc at the Isle of Man as well), which features the MotoCzysz D1-11 VDR D1g1tal Dr1ve. According to the Portland-based company, the 2011 MotoCzysz E1pc will be capable of over 200hp, from what looks like a 3-phase AC motor.

If our sources are right, the motor was built with help from Remy, and should be the real-deal come race time as it spins to over 10,000 rpm (electric racing fans, get ready for a power grudge-match between MotoCzysz and Lightning Motors). Of course, what you really came to this post looking for is a video of the motor and 2011 MotoCzysz E1pc testing on the company’s dyno. Find that goodness after the jump, though it should be noted the identities of the criminally fast have been concealed.

How Do You Build an Erik Buell Racing 1190RS?

04/16/2011 @ 7:22 pm, by Jensen Beeler8 COMMENTS

Erik Buell Racing finally has its own official YouTube channel, which is sort of strange considering how well the small company has taken to the internet and viral marketing. Sidestepping that oddity, there is of course the issue of what good is there in having a YouTube channel if it doesn’t have a video — not to worry, the folks at EBR have our backs there. We’re not sure if the EBR 1190RS is the great white hope of American sportbikes, but we like Buell’s gumption and grit to start anew in one of the worst economic climates since WWII.

For some weekend eyecandy, feast your eyes on a time lapse video of the Erik Buell Racing 1190RS motor being built, along with some cool footage of the Erik Buell Racing’s streetbike being tested on the dyno. Only 100 EBR 1190RS street machines will be made, at a price Erik Buell Racing calls comparable to “the price of a top of the line minivan,” which sounds pretty steep for a motorcycle, but will help the Wisconsin company comply with AMA homologation regulations, and race the EBR 1190RS at Infineon later this May.

Video: Motus MST Stretches Its Legs on the Dyno

02/11/2011 @ 4:56 pm, by Jensen Beeler20 COMMENTS

There might be snow on the ground for most of the United States, but things in the south are starting to heat up now that Motus has gotten its MST sport-tourer on the dyno, and for a quick ride in its latest video on YouTube. Letting the 1645cc gasoline direct-injection KMV4 motor “unleash the beast” as it were, the project seems to be coming together nicely as we’re given a rapid succession of quick-cuts on the MST’s build job.

We expect to see the built-in-America bike on city streets once the ice thaws (or Motus realizes it was 70°F in sunny San Francisco today, and makes a stop by the Golden State), and the video’s ending suggests we’ll get another installment while we wait for winter to subside.

We’re still going through the video to see if there’s any nuggets of info hidden inside. Call them out in the comments if you see something.

BMW S1000RR 191hp Dyno Run on Video

04/26/2010 @ 11:57 am, by Jensen Beeler13 COMMENTS

Ever since early reports on the 2010 BMW S1000RR suggested that the German superbike was making a claimed 190hp at the crank, the Bavarian bike sounded like a true contender against the Japanese dominated  market. Then when we heard that BMW may have been sandbagging those figures, and bikes were popping up wtih 190hp at the crank, it definitely piqued our interest.

With disbelief we weren’t sure what to make of the new BMW, and it seem we’re in the same boat as the folks over at, as they’ve gotten their hands on a S1000RR and put it on a DynoJet to see for themselves what the bike could do. The result? 191hp. Check the video after the jump

Video: MotoCzysz D1-10 Electric Motor on the Dyno

04/18/2010 @ 5:03 pm, by Jensen Beeler8 COMMENTS

While the video of MotoCzysz putting their new D1-10 electric motor up on the dyno is not terribly captivating (it’s hard to see anything really moving since all the fun bits are inside the motor’s casings), the performance figures the company quotes surely are impressive. The liquid-cooled IPM motor makes 250lbs•ft of torque, generates over 100hp, and employs a proprietary cooling system to allow a higher percentage of that peak power to be used over extended periods of time. This is particularly important because of the large gap between peak power figures and sustainable power figures in the electric motorcycle world, with the latter being the more important figure to quote.

MotoCzysz: 0-120mph in 11 Seconds

05/19/2009 @ 12:31 am, by Jensen Beeler6 COMMENTS


Last week we showed you the MotoCzysz electric sportbike, the E1pc, dyno testing on video for the first time. That test, and all previous tests that have been done, were conducted with the batteries not installed into the bike. This week we bring you footage of the electric race bike all gussied up and ready to go with its battery packs on-board.

Seeing the bike take a closer shape to its racing form is certainly a sight in of itself, but what intriuged us was how fast this bike can go. In the video linked after the jump we see the bike clearly hit 120mph. It does this in only 11 seconds. Sandbagging us in this video, the E1pc apparently has more, with MotoCyzsz predicting that the bike can do the 0-120mph test in a mere 7 or 8 seconds. More after the jump

AMA Checks Power-to-Weight Ratio on Pro Daytona SportBikes – A&R Checks the Math

05/07/2009 @ 12:47 am, by Jensen Beeler6 COMMENTS


AMA Pro Road Racing officials dyno tested the 10 motorcycles that qualified for Friday’s Superpole session at Barber Motorsports Park, in an effort to maintain a more competitive balance among the hodgepodge of bikes competing in the series. In their study, they found that the bikes range in power-to-weight ratios from 2.65lbs/hp to 3.14lbs/hp, with a .28lbs/hp gap between first and second ranked bikes. What is interesting about the report from the AMA is that they never named which bikes were making how much horsepower, thus leaving it a mystery who had the supreme power-to-weight advantage. Never fear, math and common sense are here. We crunched the numbers to figure out what the likely results are in this report. Our conclusions may astound you, and/or confirm your suspcions about the series, and maybe AMA road racing as a whole.

2009 Yamaha R1 Reportedly Heavier and Less Powerful than the 2007 R1

04/15/2009 @ 6:00 pm, by Jensen BeelerComments Off on 2009 Yamaha R1 Reportedly Heavier and Less Powerful than the 2007 R1


Performance Bikes magazine is reporting that their independently conducted dyno tests show that the 2009 Yamaha R1 makes less power and torque than the 2007 R1. Furthermore, Performance Bikes also got a chance to throw the 2009 R1 onto a scale, and found that the bike weights more than the 2007 version as well. In the liter-bike class its all about stronger and lighter, crossplane crankshaft or not, so is the 2009 R1 all its cracked up to be?

Norton NRV588 Rotary Testing at Donington Park

04/10/2009 @ 12:48 am, by Jensen Beeler6 COMMENTS

You may remember the news that Norton was preparing an entry into this years Isle of Man TT. Visordown has caught up with the British team at Donington Park recently, and has posted a video of the Norton team testing the rotary motor powered NRV588, and running it on their dyno. The bike sounds vicious, and the glowing exhaust pipes, menacing. It won’t be long now until we can see the fruits of Norton’s labor. Watch the video after the jump.
