On what typically would be the formal unveiling of Ducati’s next GP race bike, Ducati Corse General Manager Filippo Preziosi stood alone on the stage at Madonna di Campiglio, and instead talked briefly about the “totally new” GP12, while fielding questions from the assembled press. Releasing very little information about the team’s off-season progress, Preziosi shared very few concrete details about the new Ducati Desmosedici GP12 (you could also read that sentence to mean that the assembled press failed to press for more detailed information concerning the GP12…it really could go either way). From what information could be gleaned from Preziosi, we now know that that the new GP12 is comprised of roughly 90% new parts when compared the previous iterations of the MotoGP contender.

Expected visually to look similar the GP12′s of the past, the finalized GP12 will have an aluminum perimeter-style frame, carbon fiber swingarm, and a better balance with the motor placement. Declining to state the angle of the cylinder heads, Preziosi added some more fuel to the fire and speculation that the Ducati Desmosedici GP12 will not have a 90° cylinder arrangement. At the very least, the GP12 will allow for greater adjustment with the engine placement specs, as well as the overall geometry of the motorcycle. This should help Ducati Corse develop the GP12 over the course of the season, and set it up better for each race circuit. However, Preziosi did caution that the team was trying to compress two years worth of R&D into three months, a daunting task to say the least.

Talking to Lee Conn when Motus was on its US tour here in California, the Motus founder revealed that part of Motus’s business plan incorporates selling the Katech-designed KMV4 motor as a crate motor for enthusiasts and tuners. Though the Motus MST motorcycles will be using a 1,645cc 160+ hp version of the gasoline direct injection (GDI) motor, Katech and Motus have left plenty of beef to the KMV4′s cyclinder housings, allowing the V4 lump to be bored out to a 2L displacement.

Fanned by a recent article in Motorcyclist (and an earlier article in MCN from the same author), rumors abound that Honda is working on a 1,000cc V4 sportbike, likely to be called the RVF1000R. A supplement to Honda’s superbike offering, and not a replacement to the CBR line, the new RVF would be a more premium superbike offering, differentiating itself from its inline-four cousin in a similar manner as the Rc-45 and RC-51 motorcycles did in previous decades.

If rumors are to be believed, we could see the new Honda V4 as early as the end of this year, with the major differentiation over the CBR1000RR being both the RVF1000R’s price, performance, and exclusivity. If done properly, the new Honda superbike could be an opportunity for the Japanese company to build some brand value beyond making cheap & reliable motorcycles. While the Japanese manufacturers have a reputation for making quality bikes, their work has never been translated into lifestyle status brand value, which is something a premium superbike could help foster.

UPDATE: Obiboi has done up a Kenny Roberts paint scheme version as well. Find it after the jump.

Do you dream of Yamaha producing a V4 sport bike? How about naked-variant that supplants the popular FZ1? Does a carbon/aluminum trellis frame work for you, with a titanium exhaust of course? If you answered yes to these questions, and envision such a bike late a night when you’re forming your dream garage in, then Oberdan Bezzi has just the concept sketch for you.

Drawing on the same 1,000cc fairing-less street bike theme as the FZ1, Bezzi imagines a Yamaha with a forward-tilted V4 motor that has an almost perpendicular cylinder arrangement, and is capable of being a platform with worldly appeal.

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. Rumors had swelled that Spanish MotoGP hopeful Inmotec, who consistently fails to get its bike on the GP grid, could link up with Norton, likely in helping the British firm design its motor.

We don’t know if that partnership ever materialized, but 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.

Not to be confused with the Africa Twin, which would be missing two cylinders, Honda returns to its rugged off-road expedition-style adventure past with the Honda Crosstourer Concept. Based on the Honda VFR1200F’s V4 motor and dual-clutch transmission, the Crosstourer concept is designed to be the rugged off-roader that the Crossrunner and VFR1200F are not.

Finally unveiled, this is the much-hyped 2011 Honda Crossrunner that Honda has been releasing sketches of for the past month. A 782cc 90° V4 that’s derived from the VFR800 series, Crossrunner’s liquid-cooled, DOHC motor makes 102hp and 54 lbs•ft of torque. Honda hopes the Crossrunner will fill in a gap that is a cross between a naked street bike and an adventure bike, but has been very clear that it intends the Crossrunner to be a road-only machine (the Honda Crosstourer Concept should fill the off-road need just fine).

Sans a shaft-drive, the Honda Crossrunner will come with a chain final drive, uses an evolution of the VFR’s VTEC valve system for its 16 valves, and features Honda’s combined-ABS braking system. Road warriors get excited because the 2011 Honda Crossrunner comes with a 5.68 gallon tank. The only downside? The Honda Crossrunner is 530lbs when its on the curb. Photos and technical specifications after the jump.

While Honda won’t release more info on its new 800cc V4-based adventure bike and 1,200cc V4 adventure concept until a day or two from now, the folks at Oliepeil snapped this photo of the Honda booth, which shows a bike very similar to Honda’s teaser image. Looking very GS-esque, it will be interesting to see the results on Honda’s foray into the adventure bike segment with a V4 motor.

UPDATE: Larger photos and more details have been added.

Well here’s your first look at the 2011 Aprilia Tuono V4 R. While we don’t have official information, the Tuono V4 line seemingly comes equipped with the Aprilia Performance Rider Control package. Sharing its frame with the RSV4 superbike, the Aprilia Tuono V4 R receives a de-tuned motor with performance figures coming in at 162hp and 81 lbs•ft of torque. Like the Aprilia RSV4 Factory APRC SE, the Tuono V4 R will be fitted with APRC system, which will bring traction control, anti-lock brakes, wheelie control, launch control, quick-shifter, and rider-selectable driving modes to the naked V4.

Braking power comes from radial Brembo monobloc calipers mated to 320mm discs up front. Suspension is done by Sachs, with 43mm titanium nitride (TiN) forks and a four-way adjustable (compression, rebound, pre-load, and ride height) rear shock with piggyback reservoir. The 2011 Tuono V4 R comes with new wheels that are 5 lbs lighter than the ones that come on the Aprilia RSV4 R. We apologize for the small photos after the jump, but perhaps that’s better so as to help you avert your eyes from this abortion of a motorcycle.

Honda continues to tease its V4-based adventure bike ahead of its unveiling at EICMA next week. Finally showing off the actual lines of the machine, Honda has clearly made a cross between the CB1000R and VFR1200F in this design. Tall and purposeful, the concept clearly has the extra travel to soak-up an uncertain path, but Honda insists the bike is designed for on-road use. We dig the single-sided swingarm, but it will be interesting to see how Honda finishes off the exhaust pipe, and of course the final fit and finish of the design as a whole (the tail, like on the VFR1200F, seems to be an afterthought).
