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.

Two Enthusiasts Podcast #28 – Getting Cranky

08/15/2016 @ 7:58 pm, by Jensen Beeler12 COMMENTS


Episode 28 of the Two Enthusiasts Podcast starts with some recent news: the closure of Skully and the near-passage of California’s lane-splitting law.

The conversation about Skully quickly moves from the failed startup, to a broader conversation about helmet design and the progress of technology in this space. The show then turns to California’s lane-splitting law, and what it could mean for motorcyclists in states other than California.

Once the news items are out of the way, the show spends a bit of time talking about crankshaft design, namely what it means to have a “crossplane” crankshaft.

Further down the rabbit hole, this turns into a larger conversation about how engines make their power, and how that power is tuned for specific tasks. It’s a tough subject to do only via voice, but we think you’ll enjoy it.

As always, you can listen to the show via the embedded SoundCloud player, after the jump, or you can find the show on iTunes (please leave a review) or this RSS feed. Be sure to follow us on Facebook and Twitter as well. Enjoy the show!

2015 Yamaha R1 Spotted – DCT, 4 Cyl., & 230hp Rumored

07/18/2014 @ 6:33 pm, by Jensen Beeler28 COMMENTS


The eagle eyes at the Australian Motorcycle News bring us our first look at the 2015 Yamaha YZF-R1, as Iwata’s superbike was caught testing at the Eastern Creek International Speedway.

With the picture, comes the first rumored details of the new R1, with the biggest news being that Yamaha will bring two versions of the machine to market: one street version, and one for race homologation.

From the photo above, both models will heavily take their styling cues from the current YZF-R6, and will also continue to use a four-cylinder crossplane engine configuration — this revelation squashes any notion of a three-cylinder superbike from Iwata.

Video: A Primer on Crossplane Crankshafts

02/04/2013 @ 1:31 pm, by Jensen Beeler18 COMMENTS


Reading through the comments on the Attack Kawasaki CRT bike and its new crossplane crank, it is clear that the concept of what makes an engine have a crossplane configuration, like the one found in the current Yamaha YZF-R1, is still a bit of an enigma for some motorcyclists.

Referring to the way a crankshaft is built, with the four crank pinks at 90° from each other, an inline-four engine with a crossplane configuration fires its four pistons in a different order, and with different intervals between ignitions, than a normal engine with 180° pin positions.

A subject we’ll broach in greater detail at a later time, we thought this video from Yamaha would at least highlight some of the major differences and reasons for using a crossplane crank in a sport bike motor. Enjoy it after the jump.

Listen to Attack Kawasaki’s Crossplane CRT Bike

The 2013 MotoGP Championship season is rapidly approaching us, and while many of the teams are now making their way to Sepang, Malaysia for their first test since the winter ban period, Attack Kawasaki and rider Blake Young were out in the California desert, putting laps in on Rich Stanboli’s new crossplane-enginged Kawasaki CRT bike at Chuckwalla Valley Raceway.

Only time will tell on how Attack’s racing package performs at its three MotoGP wildcard events (Austin, Laguna Seca, and Indianapolis), but so far the project is music to our ears. The only Kawasaki with a crossplane crankshaft that we can think of, enjoy the video posted by RM Racing after the jump. And remember, it’s Friday, so no one at work would judge you if you bumped up the speakers.

No Cross-Plane Crankshaft for 2010 Yamaha FZ1

08/27/2009 @ 5:29 pm, by Jensen Beeler4 COMMENTS


MotoRevue is reporting that the 2010 Yamaha FZ1, like the 2010 Yamaha R6, will not be updated with the R1’s cross-plane crankshaft. The FZ1 is a shining example of Reaganomics, getting the trickle down technology of the YZF-R.

So, it comes with some surprise that we hear that it won’t get the MotoGP inspired crankshaft, but never fear loyal Fazzer owners, it does seem that the FZ1 will get some love in the next two years.

No Cross-Plane Crankshaft for 2010 Yamaha R6

08/14/2009 @ 9:08 am, by Jensen Beeler3 COMMENTS


Rumors are already flying about the 2010 Yamaha R6, which is due for an update this next model year. One of the prominent theories is that that supersport would inherit the cross-plane crankshaft found in the current R1 liter bike. While Yamaha has officially been quiet on this matter, R1 project leader, Toyoshi Nishida, has pretty much ruled out the possibility of that technology trickling down to the 600cc bike. However, it does seem certain that the new R6 will tip the scales at a paltry 385 pounds or less…wet.

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?
