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.

Over-Revving Caused Yamaha’s Mugello Engine Woes

06/02/2016 @ 1:58 pm, by David Emmett19 COMMENTS


Yamaha have issued an official explanation for the problem they suffered at Mugello, which saw Valentino Rossi’s engine blow up during the race, and Jorge Lorenzo’s engine blow up during warm-up on Sunday morning.

The cause given is exactly in line with the reasoning in our Mugello Sunday post-race round up: the engine overrevving as the rear wheel lifted at the end of the Mugello straight.

At that point in the track, with the bike hitting 350 km/h and nearing peak speed at top gear and at full throttle, when the rear wheel lifts over the crest at the end of the straight, the engine spins up too quickly for the rev limiter to catch.

MotoGP Tech Director: No Breach of Moto3 Rev Limit Found

03/11/2016 @ 1:53 pm, by David Emmett7 COMMENTS


MotoGP’s Technical Director has rejected KTM’s claim that Honda exceeded the official Moto3 rev limit during the 2015 season.

In an official statement issued today, Danny Aldridge said that he and his technical team had examined the official rev limiter used in Moto3 and verified that it was operating correctly, and that although there had been overshoots of the rev limit, these were very small and very brief.

Aldridge went on to confirm much of what we had found when we investigated the issue at the end of February. Speaking to Peter Bom, crew chief of 2015 Moto3 world champion on a Honda Danny Kent, Bom explained that the issue had been about the way in which Honda had optimized the point at which the rev limiter cut in, and this is what had caused the confusion.

KTM Claims Honda Exceeded Moto3 Rev Limit

02/24/2016 @ 4:01 pm, by David Emmett18 COMMENTS


Were Honda exceeding the Moto3 rev limit in 2015? This is the accusation made by KTM Sports Director Pit Beirer in a story on the German-language website Speedweek.

Beirer alleges that KTM came across the issue when talking to riders who switched from Honda to KTM this year, who were complaining of how abruptly the KTM hit the rev limiter.

Beirer further claims that KTM were able to look at the data of the Honda Moto3 machine held by a former Honda mechanic. In that data, he alleges, the Honda ran flat out to the 13,500 RPM rev limit, then gradually tailed off to 13,600 RPM.

These claims, if they are true, would be a massive breach of the Moto3 regulations. Though Beirer does not mention Danny Kent by name, the insinuation was that this may have been a factor in a Moto3 title that ended up being decided by just six points.

We spoke to Peter Bom, crew chief to Danny Kent both this year and last, during his successful Moto3 championship campaign, and a key factor in the Englishman’s title. Bom denied the allegations, and explained that the claims can only be based on Beirer misinterpreting the facts.

The difference between the Honda and KTM Moto3 rev limiter strategies was marked, Honda having invested a large amount of time and money in optimizing both gear change and rev limiter strategies, making the bike as smooth as possible and as easy to ride.

Minimum Weights To Be Reduced Soon in MotoGP

05/28/2014 @ 3:32 pm, by David Emmett8 COMMENTS


The news that 340mm carbon brake discs are to be allowed once again in MotoGP has rekindled a debate that has been going on behind the scenes for some time.

The move to allow the discs at all tracks, and not just Motegi where they are already compulsory, has come as both power and weight of the MotoGP machines has grown over the past three years. But the real solution lies in reducing the minimum weight.

There was a certain irony in the moment chosen by the Grand Prix Commission to ban carbon discs larger than 320mm. The move – made for reason of cost savings and rationalization – came just as MotoGP was to return to 1000cc, meaning the bikes were about to reach higher top speeds.

Compounding the problem, the minimum weight was also increased. The initial proposal was to raise the minimum from 150kg, the weight of the old 800cc machines, to 153kg. However, to make life easier for the CRT machines, the weight limit was raised even further, in two steps, to 157kg in 2012 and 160kg in 2013.

In the space of two years, engine capacity had been increased by 25%, leading to a power increase of around 10%, while weight had also been increased by nearly 7%. It was a recipe for brake problems, and that is precisely what occurred.

Factory 2 Rules Adopted for 2014 Season: Spec-Software Compulsory in MotoGP from 2016 Onwards

03/18/2014 @ 8:16 am, by David Emmett34 COMMENTS


After a week of debate and discussion, the Grand Prix Commission has finally reached an agreement on the Factory 2 class. It took many hours of phone calls, and full agreement was not reached until late on Monday afternoon, but the agreement contains some significant changes to the long-term future of the MotoGP championship.

The Factory 2 proposal has been adopted in a slightly modified guise, with any manufacturer entering in the Open class liable to lose fuel and soft tires should they win races. But the bigger news is that the full MotoGP class will switch to use the spec software and ECU from the 2016 season, a year earlier than expected.

The proposals adopted by the GPC now lays out a plan for MotoGP moving forward to 2016. In 2014 and 2015, there will be only two categories – Open and Factory Option – with the set of rules agreed at the end of last year.

The new proposal sees manufacturers without a dry weather win in three years to compete as Factory Option entries, but with all of the advantages of the Open class – more fuel, more tires, no engine freeze and unlimited testing. However, should they start to achieve success, they will start to lose first fuel, and then the soft tires.

If Ducati – for it is mainly Ducati to which these rules apply, as they are currently the only manufacturer who are eligible at the moment – score 1 win, 2 second place finishes or 3 third places during dry races, then all bikes entered by Ducati will have their fuel cut from 24 to 22 liters for each race.

Should Ducati win 3 races in the dry, they will also lose use of the softer rear tires which the Open category entries can use. If Ducati were to lose the extra fuel or tires during 2014, they would also have to race under the same conditions in 2015.

Official: MotoGP Drops Rookie Rule & Single-Bike Rule – But Restrictions On Factory Bikes Introduced

07/02/2012 @ 5:08 pm, by David Emmett9 COMMENTS

Much was expected of this Friday’s meeting of the Grand Prix Commission, but in the end, the decisions taken were relatively minor. Dorna, IRTA, the FIM, and the MSMA agreed on a number of proposals which had widely been expected, but made no real progress on the major rule changes expected for the 2014 or 2015 season.

The rule change with the biggest immediate impact was the dropping of the Rookie Rule, as we reported during the Silverstone round of MotoGP. The dropping of the Rookie Rule, which prevents new entries into the MotoGP class from going straight to a factory team, opens the way for Marc Marquez to join the factory Repsol Honda team next season. Contrary to popular opinion, however, the rule was not dropped at the request of HRC, but rather of the Honda satellite teams themselves, both Lucio Cecchinello and Fausto Gresini fearing the disruption that Marquez would bring for just a single year.

No MotoGP Rev Limit Until 2014

05/01/2012 @ 3:03 pm, by David Emmett6 COMMENTS

Jerez saw another round in the game of bluff poker being played between Dorna and the manufacturers over the future of MotoGP’s rules, and both sides took another step closer to an agreement. Reports emanating from the discussions suggest that Dorna has made a concession to the MSMA over the rev limits, while the factories are pushing through a single-bike rule, and an agreement should be ready by the middle of the year.

Ever since the MSMA lost their monopoly over the rules at the end of 2011, when the contract between the MSMA and Dorna lapsed, Dorna has had the stronger hand, and Carmelo Ezpeleta has been pushing the factories hard for changes. The pressure is starting to pay off for Ezpeleta, as by a combination of cajoling, threats and promises, he has also reached an agreement over the future shape of the sport. MotoGP is to undergo a radical transformation from the pure technology exercise that was the 800cc era, and become a sport focused on entertainment, where costs are kept in check.

Official: 2011 Kawasaki ZX-10R Gets 750 RPM Redline Reduction Because of EPA Noise Laws

10/08/2010 @ 3:58 pm, by Jensen Beeler14 COMMENTS

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.
