Is Yamaha Using A Seamless Gearbox? The Data Says No

By 17 Comments

Ask Jorge Lorenzo if there is one thing which the Yamaha needs to allow him to compete with the Hondas, and he will tell you it is a seamless gearbox. The system used by HRC on the Honda RC213V allows the riders to shift gear while the bike is still leaned over, without upsetting the machine. It is an important factor in the Honda’s better drive out of corners, as Dani Pedrosa, Marc Marquez, Stefan Bradl, and Alvaro Bautista can shift gear earlier and make optimum use of the rev range to accelerate harder.

That Yamaha is working on a seamless gearbox is no secret, with Yamaha’s test riders currently racking up the kilometers around tracks in Japan, testing the reliability of the maintenance-intensive system to the limit before using it in a race. Recently, however, Spanish magazine SoloMoto published an article suggesting that Yamaha has already been using its new seamless gearbox since the beginning of the season.

In evidence, the magazine pointed to an apparent difference in fuel consumption between the factory Yamahas and the satellite bike of Cal Crutchlow. While both Cal Crutchlow and Valentino Rossi made mistakes at Qatar, only Rossi was able to recover, and then battle with Marc Marquez for the podium. The theory put forward by SoloMoto was that the smoother transition between gears gave both better drive and lower fuel consumption, as the ignition is cut for a much shorter period, wasting less of the limited gasoline the MotoGP bikes are allowed.

My own enquiries to check whether Yamaha was using a seamless gearbox or not always received the same answer: no, Yamaha is not using the seamless gearbox. The reason given was simple: with Jorge Lorenzo defending his title and Valentino Rossi in the race for the championship, they simply cannot afford to have a single DNF down to a mechanical failure of the new-fangled seamless gearbox. The risks involved were just too great, especially when taking the reduction in engine allowance into account, with just five engines allowed all season, down from six in 2012.

To test this denial, I went out to the side of the track on Friday morning at Jerez to record the bikes as they went by. I sat at the exit of Turn 10, Peluqui, and recorded the bikes as they accelerated towards Turn 11. It is a spot where they change gear once, before braking briefly for Turn 11 and then powering on to Turn 12 and the final short straight and hairpin.

OCC Coming Back to TV? — Universe Collapses in on Self

By 11 Comments

After a very public father/son break-up between Paul Teutul Sr. and Paul Teutul Jr., a steroid-ring scandal involving Paul Sr., and finally a bankruptcy proceeding, it appears that Orange County Choppers is the impossible to kill multi-headed hydra of doom that we all knew it was, as the custom chopper shop is once again headed to the small screen and recruiting some talent, on and off the show.

Looking for “someone who will work alongside Paul Senior, running the shop and helping build some of the best custom motorcycles in the world,” OCC says it will be back on television with a new show later this month (last we heard, the show was still looking for a creative director too). Please for the love of god, will someone give this man the attention he craves so dearly??! Or, just shoot us in the face.

Alstare Superbike Concept by Team Alstare

By 9 Comments

We love us some concept bikes here at Asphalt & Rubber, and we have featured more than a few pieces of stunning design and imagination on our pages. Though, we can’t remember the last time one of these works of art were brought to us by a legitimate racing team, but that is what we have here with the Team Alstare Superbike Concept.

A nod to the former Suzuki team’s return to the World Superbike Championship as the Ducati factory squad with Carlos Checa and Ayrton Badovini, Alstare has enlisted the help of designer Serge Rusak of Rusak Kreaktive Designworks to ink the shape of its futuristic Superbike concept, while Tryptik Studios handled “bringing the form to life” with its 3D modeling prowess (video after the jump).

Transcript: The Gay Question at Jerez

By 22 Comments

If you didn’t watch Thursday’s pre-event press conference for MotoGP at Jerez, it is worth a viewing right to the end (assuming you have a MotoGP.com account). Building off the news about the NBA’s Jason Collins coming out as gay in a self-written feature in Sport Illustrated, my good colleague David Emmett had the courage to inquire about the culture and acceptance of the MotoGP paddock for homosexual riders.

I will let David write in his own words the mood and response to the evening’s press conference, as well as address the comments, criticisms, and opinions put forth later on Twitter by members of the paddock, when learning about the event. For the sake of accuracy though, after the jump is a full transcript of David’s question, as put to riders Cal Crutchlow, Jorge Lorenzo, Marc Marquez, Andrea Dovizioso, Stefan Bradl, and Scott Redding, as well as those riders’ responses to David’s inquiry.

2014 Suzuki GSV-R Spotted Again

By 15 Comments

News that Suzuki plans on returning to the MotoGP Championship in 2014 should be old information for dedicated Asphalt & Rubber readers, and the Japanese company’s inline-four race bike was already spotted doing test laps last year by the eager eyes at Cycle World.

Well the American print-mag has another set of eyebrow-raising high-quality photos of the 2014 Suzuki GSV-R to mull over from the Motegi race track, along with some technical insights provided by the venerable Kevin Cameron.

Head over to Cycleworld.com to read Cameron’s analysis (and see the bevy of great photos the magazine has published), but understand that while the secrets revealed may be fewer than last time’s inline-four revelation, one thing is for certain: Suzuki’s MotoGP package looks to be very well polished in its design.

It is clear that the Japanese manufacturer has clearly taken some notes from the work produced by its fellow countrymen. Expect to see the new Suzuki GSV-R (or whatever the boys at Hamamatsu end up calling it) in a few formal GP tests later this summer, with Randy de Puniet heavily tipped to be Suzuki’s test rider.

BMW F800GS Adventure – Germany’s Middleweight ADV

By 7 Comments

A surprise addition to BMW Motorrad’s 2013 model line-up, zie Germans have announced a new middleweight adventure-tourer, the 2013 BMW F800GS Adventure. Like its larger predecessor, the BMW F800GS Adventure is a more travel-ready and off-road capable build of the recently updated BMW F800GS motorcycle.

Featuring a larger windscreen, panniers, and a bigger fuel tank capacity (2.1 gallons larger, for a total of 6.3 gallons of fuel), the BMW F800GS Adventure keeps the same 85 hp, liquid-cooled, 798cc, parallel-twin engine found on the F800GS, as well as the same chassis configuration.

ABS comes standard, though the Automatic Stability Control (ASC) and Electronic Suspension Adjustment (ESA) systems will be made available as factory-fitted options — i.e. “options” you will have no option but to buy while at the dealership.

Kevin Schwantz Returns to Motorcycle Racing – Enters the Suzuka 8-Hours with Team Kagayama

By 21 Comments

Former 500cc World Champion Kevin Schwantz has certainly been in the news a bit these past few months, mostly for his involvement and falling out with the Circuit of the Americas and the Americas GP, but also more recently for his comments regarding Dani Pedrosa — we also sat down with Mr. Schwantz in Austin, and the Texan gave us some sobering insight into the future of American road racing.

As if all that wasn’t enough, Schwantz is making a return to two-wheeled racing, and has entered the prestigious Suzuka 8-Hours endurance race with Team Kagayama. One of three riders on the team’s Suzuki GSX-R1000, Schwantz will race with Noriyuki Haga and team owner Yukio Kagayama during the eight-hour event.

Öhlins Releases a Semi-Active Suspension Upgrade for the Ducati Multistrada 1200 S – But, What’s Next?

By 19 Comments

An interesting development on the aftermarket side of things has graced our desks, as Öhlins has released a “suspension control unit” (SCU) that upgrades the electronically adjustable suspension on the Ducati Multistrada 1200 S so that it becomes a semi-active suspension system. Whhhaaaat??!

So, if you’re the proud owner of a pre-2013 Ducati Multistrada 1200 S, and you think that your electronically controlled Öhlins suspension is no longer boss, now that Ducati has released its Sachs-powered “Skyhook” semi-active suspension pieces on its new batch of Multistrada sport-tourers, there is a remedy for your motolust.

Up-Close with the 2013 Yamaha YZR-M1

By 19 Comments

In case you missed our exhaustive coverage of the Grand Prix of the Americas, those fools at Dorna gave me pit lane access this MotoGP season. So while the whole paddock waits for the Spaniards to come to their senses, I don’t plan on wasting the opportunity to share with our readers our extreme access to motorcycling’s premier racing class. Accordingly, here comes another installment into our ever-continuing “Up-Close” series, featuring the very finest Iwata has to offer: the Yamaha YZR-M1.

Over the past few seasons, Yamaha has managed the power-deficit created by the Honda and Ducati machines by having ballerina like handling. Truly at home only when the machine was tipped-over to the extreme, the edge-grip and handling of the Yamaha YZR-M1 has been its counterpoint in the ongoing MotoGP-design argument.

A true GP bike, in the sense that it requires a riding style that has been cultivated from years of 125cc & 250cc two-stroke racing, the flowing lines of the M1 on the race track have been a stark contrast to the harsh point-and-shoot styles seen more so on the Ducati Desmosedici, but also more recently on the Honda RC213V as well.

However now with HRC having developed a seamless gearbox for the RCV, the battle of Honda’s motor vs. Yamaha’s chassis has changed. Where Yamaha riders used to beg the Japanese factory for more horsepower (they still do, by the way), they know find themselves asking for parts to combat the Honda’s ability to get on the power while still at extreme angles — an attribute once reserved only for the Tuning Fork brand.

Thirty 2000px-wide photos are waiting for you after the jump.

Trouble Broods for Husqvarna as Austrians Come to Varese

By 8 Comments

Only a couple of months after Husqvarna?s sale by BMW to Austria?s Pierer Industries, the storied motocross brand is once again making headlines, unfortunately of the wrong sort.

Reports from the La Provincia di Varese website, Varese News, as well as motorcycling’s GPOne are saying that the acquisition of Husqvarna has revealed significant problems with massive unsold inventory, labor, and the existing business plan.

As of Monday the 22nd of April, Pierer Industries announced that the factory will be closed until further notice, and let go all of the 211 factory workers employed by Husqvarna. The only staff remaining are in the sales and marketing departments, about 30 people.

Up-Close with the Ducati Desmosedici GP13

By 40 Comments

It’s hard to get up-close with the Ducati Desmosedici GP13. For starters, she’s always traveling somewhere — a slave to her jet-setter lifestyle. And, when she finally touches down long enough for you to get a glimpse of her, she’s surrounded by men in red uniforms, who whisk her out of sight almost immediately.

Occasionally though, she gets all buttoned-up and makes a public appearance, and if you have the right credentials (not an easy feat in its own right), you can elbow your way in for a look at her scarlet glow.

Dodging other bikes, riders, and mechanics in the hot pit lane of the Grand Prix of the Americas, we had such a brief opportunity, and thus bring you our spoils from the moment. We have been up-close with a number of race bikes, exotics, and even exotic race bikes, but the Desmosedici GP13 stands out even in that prestigious crowd.

A rolling piece of unobtanium, with the very best of what is available in the two-wheeled world gring its chassis, and yet Ducati’s four MotoGP riders struggle mightily with the machine. Maybe if we look closely enough, we can figure out why. Twenty-two 2000px-wide photos are waiting for you after the jump.
