A motorcycle is what the name implies: an engine with two wheels, and thus lends itself to being more accessible to both novice mechanics and expert builders alike. I myself gained my mechanical prowess by working not on a car, but on a motorcycle, and in the expert hands of tuners and accomplished customizers, true artistry can take place. Wherever you fall in between the two extremes of that spectrum, the ability to “print” replacement parts or new parts holds tremendous value. For someone like me, who loses small plastic tabs, screws, and other bits like it is his god-given mandate on this earth, the ability to create that lost part in a matter of minutes is a huge boon, not to mention it is easier on the wallet than the $5 nut or bolt that should cost $.01 at my local dealership.

While the Ducati Monster S4R is a special machine in its own right, using a water-cooled four-valve superbike-derived motor, this custom by Paolo Tesio caught our eye as something singularly different from the Italian brand’s fine work. First creating a custom subframe, tail section, and fork guards in CAD, Tesio’s finished motorcycle compliments the original design of the Monster S4R quite well, in a balanced “evolution, not revolution” sort of way.

Overall, our impressions of the 2012 Ducati Streetfighter 848 was that the new baby Fighter from Ducati, is a well-improved upon successor to the original Ducati Streetfighter 1098. Helping differentiate the SF848 from the higher-spec, though otherwise identical, Streetfighter 1098 S, the Streetfighter 848 takes the geometry from the Ducati Superbike 848, which means it gets a much-better handling 24.5° rakes. Ducati has also brought over the Testastretta 11° engine, which made its first debut on the Ducati Multistrada 1200, and then found its way onto the Ducati Diavel.

Smoother and easier to operate, the new Streetfighter’s 849cc motor may be down on power compared to its Superbike counterpart (132 hp at its peak, compared to the Superbike 848 EVO’s 140hp), but the SF848 has a much flatter torque curve and a power band that extends into a more useable range for urban and aggressive street riding. When compared to its predecessor, just about the only thing we don’t like about the Ducati Streetfighter 848 is the foot clearance issue with the shotgun exhaust, which limits the movement of a rider’s right foot on the Streetfighter’s peg.

Releasing these CAD drawings at the 2012 Ducati Streetfighter 848 US press launch, maybe some eagle-eyed industrial designers can come up with a solution for this reporter’s kneecap. CAD renders after the jump.

When the Moto2 Championship was conceived, the racing public was pitched the idea of exotic prototype racing machines that would be built around production-based motors. Though we did see Bimota build a Moto2 racer with the Bimota HB4, it is exotic motorcycles like the Vyrus 986 M2 that we really want to see filling the Moto2 grid. Of course with the spec-engine rules, races are being won and lost by just the smallest differences in chassis specifications, making the use of exotic designs a venerable game of Russian roulette. Don’t tell any of this to Rondine though, as the Italian firm is working hard on a unique Moto2 design of its own.

The 2012 Ducati 1199 Panigale represents a huge step in motorcycle design, mostly due to its frameless chassis or monocoque design. Using the engine as an integral component to the Panigale’s chassis, Ducati’s hallmark achievement was building an integrated headstock/airbox off the front cylinder. With the seat and subframe built off the rear cylinder, and the swingarm bolting directly to the motor, the Ducati 1199 Panigale was able to not only shed 22 lbs of its predecessor’s design, but also continues the Italian company’s new design trend of having components that take on multiple functional roles.

Norton, the Lazarus of motorcycling, continues to gain steam with its MotoGP project, as the latest news is that the British company is working on a 1,000cc V4 for its racing platform, which will debut in 2012 when the pinnacle of motorcycle racing reverts back to a liter bike capacity. MCN has snagged a CAD drawing of a Norton V4 motor that presumably is for the new GP bike. Initially the MotoGP race bike was expected to lay the tracks for a production sportbike, which could bode well for Norton fans who wanted something more than just a run-of-the-mill inline-four.

Confederate is readying its next iteration of its Hellcat series, posting these CAD renderings of the Confederate C3 X132 Hellcat on its website. Originally set to debut on Halloween of this year, Confederate has pushed back the launch date to the second quarter of 2011. For a bike that seemingly only exists on a computer screen, Confederate is being rather cheeky with its tech specs, simply stating that the new Hellcat will have 145 lbs•ft of torque, while listing the horsepower as “sufficient”.

Drawing inspiration from Daniel Simon’s Cosmic Motors series (Simon designed the Tron lightcycle in the up-coming Tron Legacy movie by the way), designer Bruno Delussu has dreamt up the Snake Road motorcycle concept. Set in a nondescript time in the future, the Snake Road uses a fiberglass body to house its internal combustion engine (apparently EV’s still haven’t taken off in Delussu’s future).

Made for fun, Delussu admits there are some deficiencies in the design (the front wheel can’t turn for example), and explains the choice of an internal combustion engine as follows: “Being a motorcyclist myself, I love the sound of a motorcycle engine (reminiscent of a raging lion), so the engine is a traditional internal combustion engine rather then electric, as the new trend would have it (a matter of ecology).”

Taking a motorcycle off the computer screen and into real life is a difficult process, and we always enjoy seeing an insight to that undertaking. As such, we present to you some wireframe drawings of the 2010 Aprilia RSV4 R to drool over. On a side note if you’re in the market for an RSV4, these images are the perfect template for designing your own bike paint scheme. Photos after the jump.
