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.

2017 Honda CBR1000RR SP – Proving Patience is a Virtue

The wait is over. The most anticipated motorcycle of the INTERMOT show is here, the 2017 Honda CBR1000RR SP. We have seen the spy photos of this new superbike, we have seen leaked details on this superbike, and we’ve mused endlessly about this new superbike. And now, we can finally replace that conjecture with fact. First off, the rumors were true. The 2017 Honda CBR1000RR SP sheds a massive 15 kilograms off its bulk, which translates into a 441 lbs mass at the curb. Power has also been increased by almost 11hp, for a total of 190hp at the crank. Honda says that these two figures combined mean a 14% increase in the Honda CBR1000RR’s power-to-weight ratio. That’s pretty astounding, when you consider that under the new fairings is still mostly last year’s bike.

Grand Prix Commission Clarifies Flag-to-Flag Regulations

08/22/2016 @ 10:02 am, by David Emmett6 COMMENTS


The Grand Prix Commission has introduced a range of measures at their meeting in Brno. Among the most important are the switch from selling Moto3 engines to leasing them, and changing the flag-to-flag procedure, in an attempt to improve safety in pit lane.

Starting from next year, the flag-to-flag procedure has been revised. The number of mechanics assisting has been reduced, with only four allowed to assist in the bike swap. Those mechanics must now wear approved helmets, which will also make them easier to identify.

Trackside Tuesday: Pardon Me, Coming Through

Cal Crutchlow Losail grid 2014 Ducati Alpinestars Scott Jones

With the start of the 2015 MotoGP Season right around the corner, we have some more changes to the official regulations that govern MotoGP.

Some changes have been talked about for quite a while, such as that when a rider comes in to swap bikes during a flag-to-flag race, the waiting bike must be closer to the track than to the pit box; lower bodywork on the bikes must be designed to catch oil and other fluids that might leak (Moto2 and MotoGP bikes must be able to catch five liters of fluids, Moto3 bikes three and a half liters); and so on.

But some other items have been added to the rules that haven’t received much attention. Why am I thinking about all of this? Something just caught my eye that will directly affect my work as a photographer on the grid.

World Superbike Considers 300cc Class & More

12/24/2014 @ 11:56 am, by David Emmett8 COMMENTS


At the last meeting of the Superbike Commission, the body which makes the rules for the World Superbike series, representatives of Dorna, the FIM and the factories agreed a number of measures which provide yet another step on the path to the future of the series.

There were a couple of minor technical updates, and two changes which point the way to the series’ long term future.

The changes to the technical regulations were relatively simple. The balancing rules, aimed at allowing different engine designs to be competitive against each other, received a number of minor tweaks resulting from the fact that those rules will now be carried on from one season to the next.

In practice, this means that results for either twins or fours will be carried over between seasons, creating a rolling balancing scoreboard, which should create a better balance between fours and twins.

The other change to the technical rules allow a manufacturer to revert to their 2014 electronics for the first two races of 2015, should the 2015 electronics cause them problems.

Basically, this will give the teams a fallback position and give them a little more time to develop the electronics. As the first two rounds are in Australia and Thailand, the risk of struggling with a system which is not completely ready to race during a period when it is impossible to test has been reduced.

The changes to the sporting regulations are more interesting, and point the way to the future of the series.

MotoGP Rules Updated: Fuel Limits, Concussion Tests, Etc

12/18/2014 @ 4:46 pm, by David Emmett2 COMMENTS


The meeting of the Grand Prix Commission, held on Tuesday in Madrid, made a number of minor changes to the rules for all three Grand Prix classes, as well as a couple of more significant revisions.

The biggest changes concerned the setting of the maximum fuel allocation from 2016 at 22 liters, and the adoption of the SCAT3 test for concussion for riders after a crash. But perhaps the most significant outcome of the meeting of the GPC is not what was decided, but what was not.

Of the various minor rule changes, a few are worthy of comment. The first is the reduction of the time penalty at the start for a rider exceeding the engine allocation in any given year.

From 2015, anyone using an extra engine will start the race from pit lane 5 seconds after the green light is displayed after the official start (once all riders on the grid have passed pit lane exit), rather than 10 seconds.

This will have little direct impact on the outcome of any races, but should make it easier for riders using an extra engine to get close to the backmarkers, and perhaps score a point or two.

New Rules for WSBK: All Superbikes to be “EVO” in 2015 & Winter Testing Banned for 2014

10/06/2013 @ 12:36 am, by David Emmett12 COMMENTS


The future of the World Superbike series is about to undergo a radical change. The EVO class to be introduced from next year onwards is to be the standard for all World Superbike machines from the 2015 season onwards. As the WSBK grids have dwindled over the past four years, World Superbikes have been looking around at ways to stop the decline of the series.

Former owners Infront were unsuccessful at stopping the rot, and now that the series is in the hands of Dorna, the Spanish series organizer has sat down with the manufacturers – previously excluded – and tried to find a way to cut costs drastically and increase participation.

The Newspeak of MotoGP’s Rules for 2014

08/28/2013 @ 6:49 pm, by David Emmett6 COMMENTS


At the same time the World Superbike rules for 2014 were announced, the revised version of the MotoGP rules, including updates for next season were also published. But unlike the WSBK rules, no press release was sent out to announce the new rulebook, as the minor rule changes had already been announced previously.

Yet this rulebook marks a sea change in the way MotoGP is defined. For 2013, MotoGP is still defined as prototypes competing with 21 liters of fuel, and an additional class of machines running under the claiming rule banner. From 2014, however, the roles are reversed. All bikes are classed as MotoGP entries, but an exception is made for teams entered under the ‘Factory Option’.

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.

Why the MotoGP Weight Limit Was Changed

03/07/2012 @ 11:16 pm, by David Emmett7 COMMENTS

The weight increase in the MotoGP class introduced for 2012 – from 153kg, as originally agreed when the 2012 regulations were drawn up back in August 2010, to 157kg – has had many repercussions. The addition of 4kg to the 1000cc MotoGP machines has been blamed for causing the chatter that Honda’s RC213V suffers from, and for complicating the pursuit of the ideal weight distribution for both Honda and Yamaha, which the two Japanese factories had spent most of 2011 perfecting ahead of the 2012 MotoGP season.

The decision was taken in a Grand Prix Commission meeting held on December 14th of 2011 in Madrid, and though it drew little comment at the time, once the MotoGP paddock reassembled at Sepang for the first test of the year, some intriguing details started to appear.’s Peter McLaren has an excellent reconstruction of the decision process, from which it is clear that the path to adoption the proposal faced was far more complex than usual. It also reveals some of the underlying tensions in both the Grand Prix Commission and the MSMA which will go on to play a major role in the rule-making process for 2013 and beyond.

Moto3 Technical Regulations Released

10/13/2011 @ 9:45 am, by Jensen Beeler2 COMMENTS

Two-stroke racing has been living in a four-stroke world, and the death blow to the smokers in GP racing has already been dealt by the GP Racing Commission. With 2012 set to see Moto3 replace 125GP as MotoGP’s introductory class, the FIM has released the full technical specifications of the up-coming, 2500cc, single-cylinder, four-stroke racing class. Designed not only to bring GP racing into the 21st century, Moto3 also aims to end the Aprilia domination that’s currently taking place in the class’s two-stroke predecessor. With companies like Honda and KTM building complete Moto3 machines, and engineering firms like Kalex working on custom chassis for the prototype 250cc engines, there certainly looks to be a bit of diversity coming to the introductory GP series.

Another issue plaguing 125GP, and GP racing as a whole, is the rising costs of competing in the sport, as evidenced by the diminishing grid size in MotoGP. With Moto2 boasting a healthy 40 bike grid, Dorna and IRTA believe they have found the secret recipe to making prototype racing work, and have applied that methodology to the new Moto3 class. Unsurprisingly then, the vast majority of Moto3’s technical regulations concern keeping costs down, especially when it comes to the series’ claiming-rule style engine & parts restrictions. It’s actually interesting to read the level of detail the GP Commission has gone through in order to head-off attempts to circumnavigate the spirit of the cheaper four-stroke series, though we might point out that water always finds its level. Check out the full Moto3 technical regulations after the jump.

GP Commission Modifies 2011 Rules

12/13/2010 @ 2:52 pm, by Jensen Beeler6 COMMENTS

The GP Commission has seen it fit to modify the rules for MotoGP, Moto2, and 125GP during the 2011 season, with perhaps the biggest alteration coming in the form of FP3 being reinstated to the Saturday schedule. For MotoGP, all practice and qualifying sessions will be returned to their one hour format (up from 45 minutes), which should make the sessions more useful for teams who has to scramble to make changes during the 45 minute format (Moto2 and 125GP will remain at 45 minute session). All the classes will see a three-wide grid format, which should be especially interesting in the compacted Moto2 field. All teams will also be allowed the use of generators on the starting grid.

Special for MotoGP, Dorna seems intent on limiting the level of electronics being used in the premiere class, and has inserted a provision that says that “in MotoGP, only the GPS provided by Dorna is permitted.” Currently MotoGP teams employ GPS systems that know which turn, and where in each turn, the bike is, and adjusts the bike’s suspension, engine map, and other settings for that corresponding section of the track.

While hyper-precise GPS systems could shave tenths of seconds off lap times, they also create an arms race in electronic controls, which in-turn raises the costs of racing. With Dorna supplying the unit, or failing to provide a GPS entirely (plot twist!), the use of such advanced electronics could no longer exist in 2011.

In addition to these provisions, Dorna has also requested applications for the 2012 Moto3 ECU supplier. Find the full release on the technical regulations and specifications after the jump.
