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.

Fresh from Italy, we get our first glimpse of the 2013 Aprilia RSV4 Factory WSBK race bike in its new livery. While the uniforms may look the same, the men wearing them have changed to some extent, and in many ways so has the Italian brand’s racing strategy.

Building its previous team around Max Biaggi, the previous incarnation of Aprilia Racing catered to every whim of The Roman Emperor — read into that as you will. But now with Biaggi’s retirement from motorcycle racing, Aprilia is forced to replace tried-and-true talent with two up-and-coming stars.

Out from behind Max’s shadow, Eugene Laverty is expected to impress this year, having shown himself a formidable rider on the RSV4 Factory last season with his sixth-place Championship finish. Seventh in the Championship himself, Sylvain Guintoli will join the Irishmen, after coming off a tumultuous season with Liberty Racing. With three race wins and six podiums, Guintoli made a definite impression, especially when he was on the slower Ducati.

With both of Aprilia Racing’s WSBK riders starting to come into their own, the Italian brand is showing a lot of growth potential in the premier production-motorcycle racing series. Time will tell on the results, but we expect a bevy of podiums from the Aprilia riders this year, and maybe a win or two. Mas photos after the jump.

We teased it to you yesterday, but today we finally have photos of the 2013 Honda RC213V in all its high-resolution glory. With the Repsol Honda squad getting a new livery package this year, the RC213V becomes quite the looker as the team sports a bit more white in their color scheme, with the effect being a more clean and fresh look for the factory Honda squad.

Debuting the team and machines at Repsol HQ in Madrid, both of HRC’s resident Spaniards, Dani Pedrosa and Marc Marquez, were on-hand for the event. With Pedrosa showing himself to be a new man in the latter-half of the 2012 season, and Marc Marquez tipped to be the new talent in MotoGP, Repsol Honda has a formidable pairing at its disposal, as well as a very solid motorcycling package.

Very much a cloak and dagger affair, it is always fairly entertaining to read the information that the manufacturers release regarding their MotoGP machines. Despite the fact that these are some of the most drool-over motorcycles on the planet, by rule of thumb the factories publish only the most general technical specifications possible.

If a company like Ducati thought they could get away with it, the release for the Ducati Desmosedici GP13 technical specifications would read something like “a racing machine with possibly two wheels and an engine” when disclosed to the press and public.

To be entirely honest, we don’t follow the adventure racing arena as much as we should, giving only a little bit of press to the world-famous Dakar Rally at the start of each year. So, we really can’t do justice to what Husqvarna and Speedbrain are doing with this factory-backed Husqvarna TE449 RR Dakar bike.

The photos are surprisingly detailed though, and are probably as close as you will ever get to a proper works rally machine, and Husqvarna gives a good accounting of the bike’s progression and current development. Rather than fake our own rewording of their story, read it after the jump. It’s pretty interesting.

It is hard to believe that the Honda CBR600RR will turn five-years-old in 2013, but the Japanese supersport has long been neglected in the Honda line-up. Actually, the phonomenon has not been limited to the 600cc sport bike, as the Honda CBR1000RR has also been left to whither in the sun for far too long. With the 1,000cc superbike getting a makeover for 2012, it looks like the CBR600RR is finally getting its turn, as well.

As such, the 2013 Honda CBR600RR gets a set of new fairings, which we must admit are rather fetching (the bodywork is good for a 6% reduction in drag, according to Honda). The Japanese company also says that the revised front section improves RAM-air, and thus midrange torque. We won’t being to tell you what’s wrong with that statement, but suffice to say the design helps the 599cc motor breath better.

Other changes include a revised ECU package, 12-spoke wheels, Big Piston forks (BPF), and re-tuned rear shock. Honda is even throwing its “Electronic Combined Anti-Lock Braking System” (C-ABS) on the 2013 CBR600RR. Wowzers. Colors are Red, Repsol Edition, & White/Blue/Red. Pricing hasn’t been released yet, which surely means a price increase is headed the Honda CBR600RR’s way.

The last of Honda’s six new models for the 2013 model year (checkout our coverage of the 2013 Honda CBR500R, 2013 Honda CB500F, 2013 Honda CB500X, & 2013 Honda CBR600RR), the 2013 Honda Gold Wing F6B is in a class of its own.

If the traditional Honda Gold Wing is the Cadillac of the motorcycling world, then the Honda Gold Wing F6B must be what the bike looks like with a drop-top. Taking the huge weekend touring machine, Honda has made the Gold Wing F6B more of a day-to-day cruiser…but not in a horrible Honda Rune sort of way.

Using the same chassis and 1,832cc flat-six motor that is found in the Honda Gold Wing, the 2013 Honda Gold Wing F6B not only looks like less motorcycle than its predecessor, but it also sports 62 lbs in less heft than the base tourer model, for a “curvy” 842 lbs curb weight.

Coming in two models, the Honda Gold Wing F6B will cost $19,999, while the Honda Gold Wing F6B Deluxe will cost $20,999, and will include a center stand, passenger backrest, and self-cancelling turn signals. Color choices are simple: black or red. Photos and tech specs are after the jump.

Where there is a full-faired 2013 Honda CBR500R, there must be a naked 2013 Honda CB500F – and thus the Universal Japanese Motorcycle (UJM) makes a proper return to American soil. Priced at a vey modest $5,499 ($5,999 with ABS brakes), the Honda CB500F is an affordable, dependable, and stylish street-naked or “standard” motorcycle for the masses.

Like the rest of Honda’s 500cc line, the CB500F is based around  a modest liquid-cooled, fuel-injected, DOHC, 180° crank, parallel-twin motor that will put down 54hp at the wheel for the US market (tiered-license countries will see a 47hp machine).

At 420 lbs ready to ride with a full tank of fuel, the 2013 Honda CB500F saves 8 lbs off its clothed sibling (click here to read our full description of the new CBR), with the lack of fairings being the real distinction between the two machines.

Available in either black or pearl white, expect the Honda CB500F to be at your local Honda dealer in April of 2013 (the ABS version is available only in black). Full technical specifications are after the jump.

More news on the 2013 Honda CBR500R, as details about Honda’s 498cc paralle-twin budget sport bike continue to unfold. A part of a larger effort to saturate the markets with 500cc-class motorcycles for the price sensitive, we can now confirm that the Honda CBR500R is one of three bikes (checkout the Honda CB500F & Honda CB500X) in the genre that will be coming to the USA next year.

Based around  a modest liquid-cooled, fuel-injected, DOHC, 180° crank, 54 rwhp, parallel-twin motor for the US market (tiered-license countries will see a 47hp machine), the Honda CBR500R is a sporty-styled no thrills sort of motorcycle. A graduation step from the Honda CBR250R, it makes sense then that the CBR500R has twice the cylinders, and thus twice the displacement — but it doesn’t come with twice the price tag.

At $5,999 for the American market, the 2013 Honda CBR500R commands less than a $2,000 premium over the $4,199 CBR250R. That price will go up to $6,499  though if you want the optional ABS package (and we know you do). Click after the jump for full tech specs.

Taking advantage of a quasi-home round for the MotoGP Championship at the German GP, Austrian company KTM debuted it latest “ready to race” machine, the 2013 KTM Moto3 250 GPR production race bike. A for-sale-version of its Moto3 Championship contender, the KTM Moto3 250 GPR borrows heavily from its GP-class predecessor, though comes in a slightly lower state of tune.

Featuring forged aluminum OZ wheels instead of magnesium ones, the production racer also comes sans Brembo brakes and WP suspension (items race teams would likely get from suppliers separately anyways). There is however one big technical difference, as KTM has reduced the bike’s maximum engine speed to 13,500 rpm, down from the 14,000 found on the factory bikes. This leaves the 2013 KTM Moto3 250 GPR production racer with just under 50hp on tap.
