It has been a while since we posted about those crazy Spaniards at Radical Ducati, but long-time readers will remember fondly the exquisite custom motorcycles that Pepo and Reyes have created from the various pieces of Ducati’s finest.

It is hard to pick a favorite from machines like the Radical Ducati RAD02 Imola Cafe Racer, Radical Ducati Café Veloce, Radical Ducati Mikaracer, Radical Ducati Raceric, and Radical Ducati RAD 02 Corsa EVO, but our moto-lust keeps bringing us back to the Radical Ducati 9½ - a café racer styled motorcycle that uses an ST2 motor, a Monster 900 frame, and a 916 fuel tank and swingarm.

Getting its name from the ST2′s 944cc engine displacement, the 9½’s designation should tip-off where the Spanish firm has gone in its creation with the Radical Ducati 7½ Sportiva. Another water-cooled machine, the 7½ Sportiva ups the ante with the Ducati Superbike 749R taking the honor as its donor bike, while still remaining true to its predecessor’s café racer look and feel.

Visual aesthetics have always been something of import and interest to me, a trait that is probably tied into the fact that I am visual learner. So it interests me when we see subtle changes having a great affect on a design.

Take the new Repsol livery on the 2013 Honda RC213V — the simple change from black to white creates a significantly different visual understanding of the MotoGP bike, though the basic idea of the livery remains the same.

We can see the same process with the Ducati 1199 Panigale S Nero by Commonwealth Motorcycles, as the Kentucky-based Ducati shop has massaged in a bit black paint on the already stunning Ducati 1199 S Tricolore paint scheme (work by Robbie Nigl of Peach Pit Racing).

The effect? A whole new take on an already very classy looking machine. Nice work guys…now let’s talk about posting some hi-res photos next time, eh? Far too small pictures are after the jump.

Regular readers will know that I am not a big chopper guy, but every now and then one comes along that tugs enough on this sportbiker’s heart strings that I feel compelled to post about it. Such is the case with the Benchmark by Walz Hardcore Cycles, whose close proximity to the F1 course in Hockenheim, Germany certainly must play a factor.

I am fairly confident that the Öhlins superbike suspension, carbon fiber wheels, carbon/ceramic disc brakes, and debadged Akrapovic exhaust can aren’t going to really make the difference on this low-slung S&S-powered motorcycle, but they certainly do add to the bike’s sporty lines.

The streamlined sporty-chopper look has always worked well on me, and the Benchmark is no different with its brushed aluminum metal bodywork and carbon fiber accent pieces. I can’t say that I am a fan of the Ducati Monster headlight though, a design element that kills the donor machine for me.

With pricing that starts at €124,900 (€149,900 for the bike shown here), there is a hefty dose of sticker shock that comes with the Benchmark as well. So, we doubt one will find its way into your garage anytime soon, but for now it is something nice to look at, even if the chopper thing isn’t your bag of two-wheeled fun.

If you don’t follow the work of Nicolas Petit, you should. The French designer has been inking some of the most striking motorcycle concepts in the industry, and the best part is many of them are coming to life thanks to BMW accessories provider Wunderlich.

Refusing to let go of the thesis provided BMW HP2 Sport, Petit envisions BMW’s new semi water-cooled boxer engine (first seen on the 2013 BMW R1200GS) as providing the basis for a new sport bike in the HP2′s vein, complete with a single-sided swingarm, dual undertail exhaust, and Öhlins suspension.

It might be a tough sell now that the BMW S1000RR and BMW HP4 have hit dealership floors, but there is something really quite elegant in Petit’s design, and we imagine there are more than few weekend riders who wouldn’t mind such a unique machine with a boxer’s punch.

Last year, our Christmas was ruined with the sighting of the Pierobon X60R sport bike. A small Italian company based in Bologna, for those who aren’t in the know, Pierobon has ties to some big projects in MotoGP & WSBK.

Known for their trellis chassis designs, the Pierobon X60R is the company’s two-wheeled flagship (be sure to checkout the Pierobon F042 street bike). We lusted after the X60R last year, you wanted one under your Christmas tree, and we all had to learn how to live our lives with disappointment afterwards.

Discontent to call things done, Pierobon has revised the X60R over the past year, with the most noticeable change being the Ducati Monster 1100 EVO air-cooled v-twin lump. Putting a little bit more pep in the bike’s step, Pierobon has also revised the chassis, namely the X60R’s swingarm.

Derived from the company’s GP designs, the chain-side of the swingarm has been fully enclosed, presumably for increased rigidity. Pierobon has also increased the size of the oil-cooler radiator to help with heat transfer on the more powerful motor.

For almost two years now, we have been waiting for Bottpower to finished its BOTT XR1 custom motorcycle. Starting with an air-cooled v-twin motor from a Buell XB, the BOTT XR1 is the perfect intersection of old-school flat tracking and high-tech street shredding — we’re not sure if we should strap on a steel shoe, or get some fresh knee pucks. Available as a stand alone machine from Bottpower, the Spanish firm also plans on making a kit for XB owners.

Built with an ample amount of carbon fiber, Bottpower used the stock eight-piston Buell 1125R Brake system (with ISR levers for the front brake and clutch). For the rear suspension an Öhlins shock has been implemented, while the under-slung exhaust is from Torque Hammer. The flat handlebar is by Easton, while the gauges are from Motogadget. If don’t have a street tracker on your holiday wish list, we suggest a revision. Tasty photos after the jump.

We have to admit, we’re sort of a sucker for the tri-color paint scheme on the Ducati 1199 Panigale S Tricolore, and it broke our hearts seeing one of these $28,000 bikes hit the dirt during our track day this weekend. Classy and understated, the Italians constantly remind us that less is more, but why should the Panigale get all the fun? The folks at Motovation Accessories seemingly agree, and have dressed up their Ducati Multistrada 1200 S Touring in the Tricolore’s paint — naturally, we likey.

Asphalt & Rubber may be known for the over-enjoyment of a certain sci-fi dynasty that started in 1977, but we are group of equal opportunity geeks/nerds/virgins here, and have just as much room in our hearts for the toaster-fraking good times that were provided by the re-imagined Battlestar Galactica series.

While we stayed up late at night, wondering if Kara “Starbuck” Thrace was in fact a Cylon, it turns out that Katee Sackhoff, who played the rebellious Viper pilot on the hit show, was instead probably dreaming of her next two-wheeled toy: Classified Moto’s KT600.

It is hard to believe that the “Biuta” began life as Ducati Multistrada, as it really looks nothing like the air-cooled Terblanche-penned bike. Getting more of Streetfighter meets Monster look and feel than the lines of the Multi, the Biuta is one hot looking machine, no matter which flavor of Desmo you prefer. Made by Carlo Roscio and his brother, the two brothers from Pavia, Italy spent over two years getting the Biuta right — and get it right they did.

Not too ostentatious, and not too sublime, the reincarnated 2003 Ducati Multistrada 1000DS looks great in powder blue, and has a tasteful mix of parts that allures to both the form & function crowds. We particularly like the custom Zard exhaust and side-mounted radiator, though we would hate to have to be the one to make all those many, many perfect welds. The only thing we don’t like? The far-too-tiny photos found after the jump.
