We already covered the Honda MSX125 monkey bike when it debuted at the start of this year, and at the time we knew that the tiny street-terror would be a world market machine. Confirming our hopes at the time of its launch, Honda Motor Corp. has announced that it intends to bring the MSX125 to the United States, renaming it the Honda Grom.

The 2013 Honda Grom will come with just under 10hp, and features a four-speed gearbox that is mated to a 125cc single-cylinder motor, which comes from the common-parts bin of the Japanese company’s popular Honda Wave 125i scooter. Fuel-injected, 225 lbs at the curb when topped-off with its 1.45 gallons of fuel, and priced at $2,999 MSRP, we think Honda hit its mark with an affordable, bulletproof, and fun grocery-getter.

Track day enthusiasts, we have found your perfect pit bike; new riders, we have the ideal machine for you to cut your teeth on, while still being “cool” in the eyes of your more experienced riding friends; and for those who are vertically challenged, your 29.7 inch inseam machine is ready. More photos after the jump, but note America will only be getting the red & black models.

Shipped up and on its way to the Isle of Man, we can finally now see more than test shots of the Mugen Shinden Ni and get its basic racing specifications. The electric superbike that John McGuinness will ride in the 2013 TT Zero race at the Isle of Man TT, the Mugen Shinden Ni represents that evolution of the Japanese firm’s design, having now a TT race under its belt.

Like its main competitor MotoCzysz, Team Mugen is eyeing a 110 mph lap around the Mountain Course, which would be a pretty remarkable one-year advancement for either team. With Mr. McPint at the helm, and seemingly brimming with on-board energy, Mugen is a serious contender for the top stop on the podium. It should make for some good racing in a few weeks’ time.

John Shofner is back with another one of his short films for Bell Helmets, and like the first one, it is some two-wheeled goodness for your Wednesday afternoon. Following JD Beach as he hosts his personal hero Troy Bayliss for a few days flat track fun, it is just another low-key day of playing in the Kentucky mud for these two riders.

It is pretty cool to see two different generations of road course racers come together, and JD is quick to remind us of Troy’s epic wild card victory at the Valencian GP on the Ducat Desmosedici GP6. If this flat track thing looks like your cup of tea, the AMA Pro Flat Track series is going to be live-streamed this year. It’s great two-wheeled racing (even better in person), and we highly recommend you go check it out.

Mission Motors tweeted out something interesting just a moment ago, a link to a new website for Mission Motorcycles. Teasing there a photo of the Mission R, it would seem that the electric superbike that does competitive AMA Supersport lap times at Laguna Seca, is finally set to come to production.

The stars have been aligning these past few months for such an occasion, with rumors that an old Mission Motors investor was back in the mix, and looking to bring the Mission R to production. You may recall that Mission Motors made a course correction away from the two-wheeled world, focusing instead on supplying the automotive world with electric-drive components.

That change of course saw the departure of two Mission Motors founders, and the heartbreak of two-wheeled enthusiasts, petrol and electric alike, who wished to see the Mission R come to market. With layoffs reported at the San Franciscan startup just six months ago, it would seem more changes are afoot for the EV company, but we think you will like the sound of this.

KTM is shaping up to be the brand of 2013. Surpassing BMW Motorrad in outright unit sales, and becoming the largest motorcycle brand in Europe, zie Austrians have been on a tear with their small-displacement machine strategy. Most of that move has been buoyed by KTM’s partnership with Bajaj, which in-turn owns a very sizable minority stake in the Austrian company, but KTM also has been making other moves as well, like the acquisition of Husqvarna by CEO Stefan Pierer and his company Pierer Industrie AG.

Surprisingly, what has been occurring in KTM’s boardroom is almost overshadowing what is occurring in the company’s model line-up, with the KTM 1190 Adventure set to finally come to the USA later this year, almost a year after its European debut, as well the upcoming release of the KTM 390 Duke and its sport bike and adventure variants. Perhaps lost in the wash is the 2013 KTM 690 Duke, which is a new machine for the US market this year.

A single-cylinder hooligan-maker, the KTM 690 Duke is 330 lbs (curbside without fuel) and 67hp of two-wheeled fun, and we hope that the Austrians bring the KTM 690 Duke R our way as well. While we are on the topic of things missing from KTM’s American line-up, a decent supersport is painfully obvious, yet we can’t see the folks at KTM following the paths of other brands. That’s where our friend Luca Bar comes to mind with his latest concept: the KTM RC4.

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).

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.

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.

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.

Any loyal Valentino Rossi fan knows that The Doctor is an avid four-wheel driver. Testing everything from Rally to Formula 1, many think that Rossi will go to the four-wheel world after his time in the two-wheeled world is done. Which series that could be is up for contention (we very much doubt it will be in the Australia V8 cars though), though the name NASCAR might have to be added to the list.

Fresh off Sunday’s Grand Prix of the Americas, Monster Energy gave Rossi a chance to lap with Kyle Busch’s 650hp Toyota race car at the 1.5-mile Charlotte Motor Speedway. Though Rossi started out slow, he ultimately set some impressive numbers (what would have been a Top 15 in the Nationwide Series practice at Charlotte). Of course, it helps when you have the one of the most successful NASCAR drivers in the series giving you track notes and talking in your ear over the radio.
