We have featured the work of Peirobon on Asphalt & Rubber before, as the boutique firm from Bologna makes some intriguing air-cooled Ducati-powered sport bikes for discerning buyers, among other things.
Pierobon is also one of the companies we are looking forward to seeing at this year’s EICMA show, as the firm has something special this year for its booth display: a trellis frame kit for the Ducati 1199 Panigale.
After the initial disappointment at the death of the 250cc two strokes, the advent of the Moto2 class raised hopes that Grand Prix racing would enter a new era of chassis innovation, as the teams spent the money saved on engine development on exploring novel solutions to the problem of hustling a motorcycle around a circuit is the shortest time possible.
The first set of designs unveiled did little to feed that hope, with most bikes being of the aluminium twin beam variety which is standard in most sports and racing machinery, with a couple of tubular trellis frames thrown in for good measure.
Even that variety did not last. The trellis frames were the first to go – mostly as a result of the extra weight the design created – and the number of chassis manufacturers dropped from 13 in the first year to 6 in 2013.
Even that figure gives an inflated picture of the variety in the paddock: 28 out of the 32 permanent entries form Moto2 this year use either the Kalex, Suter or Speed Up chassis. The bikes vary in stiffness, in aerodynamic detail and in aesthetics, but other than that, they are virtually identical.
So why is there no real innovation in the Moto2 paddock – or MotoGP or Moto3, for that matter? The answer is simple, and has been discussed here many times before. The attitude which characterizes the paddock in technical terms is not one of the fearless pursuit of knowledge and innovation.
It is not a hotbed of blue sky thinking and adventurous engineering. It is a place of conservative evolution, of cautious refinement, where proven concepts are polished to as near perfection as possible.
Max Biaggi’s brief return to MotoGP is over. After two days of testing Ducati’s MotoGP bike at Mugello, filling in for the injured Ben Spies, Biaggi returns to his day job, as TV commentator for the Italian coverage of World Superbikes.
Two short days were not really enough time for Biaggi to get back to grips with a MotoGP bike, especially given that testing stopped early on both days after rain started to fall in the afternoon. Biaggi faced two problems, returning to riding at speed for the first time in eight months, and returning to a MotoGP bike for the first time in over seven years.
Given those difficulties, the times he set in the end were respectable. According to GPOne, who had reporter Luca Semprini on location, Biaggi’s best time was a lap of 1’52.1, which would have seen him qualify in 23rd position for last Sunday’s MotoGP race, just ahead of Hiroshi Aoyama on the FTR Kawasaki CRT machine.
“This is the reality,” factory Ducati rider Andrea Dovizioso told the media after finishing 7th at Qatar, some 24 seconds off the pace of the winner, Jorge Lorenzo. Hopes had been raised on Saturday night, after the Italian had qualified in fourth, posting a flying lap within half a second of polesitter Lorenzo.
While Dovizioso’s qualifying performance had been strong, he had at the time warned against too much optimism. The Desmosedici is good on new tires, but as they begin to wear, the chronic understeer which has plagued the Ducati since, well, probably since the beginning of the 800cc era, and maybe even well before that, rears its ugly head and makes posting competitively fast laps nigh on impossible.
The problem appears to be twofold. Firstly, a chassis issue, which is a mixture of weight distribution, gearbox output shaft layout, frame geometry, and to a lesser extent chassis flexibility. And secondly, a problem with engine response, an issue which is down in part to electronics, and in part to Ducati still using just a single injector per throttle body.
Just over 18 months ago, I wrote a long analysis of what I believed at the time was the main problem with Ducati’s Desmosedici MotoGP machine. In that analysis, I attributed most of the problems with the Desmosedici to the chosen angle of the V, the angle between the front and rear cylinder banks.
By sticking with the 90° V, I argued, Ducati were creating problems with packaging and mass centralization, which made it almost impossible to get the balance of the Desmosedici right. The engine was taking up too much space, and limiting their ability to adjust the weight balance by moving the engine around.
Though there was a certain logic to my analysis, it appears that the engine angle was not the problem. Yesterday, in their biweekly print edition, the Spanish magazine Solo Moto published an article by Neil Spalding, who had finally obtained photographic evidence that the Honda RC213V uses a 90° V, the same engine angle employed by the Ducati Desmosedici. Given the clear success of the Honda RC213V, there can no longer be any doubt that using a 90° V is no impediment to building a competitive MotoGP machine.
The photographic proof comes as confirmation of rumors which had been doing the rounds in the MotoGP paddock throughout the second half of the 2012 season. Several people suggested that the Honda may use a 90° angle, including Ducati team manager Vitto Guareschi, speaking to GPOne.com back in November.
I had personally been lucky enough to catch a glimpse of a naked RC213V engine at one rain-soaked race track in September, but while the glimpse through the window may have been good enough to form the impression of an engine that looked like it may have been a 90°V, it was a very long way from being anything resembling conclusive, and nowhere near enough to base a news story on.
Spalding’s persistence has paid off, however. The British photographer and journalist is a common sight wandering among the garages, either first thing in the morning, as the bikes are being warmed up, or late at night, while the mechanics prepare the machines for the following day.
At some point, the Honda mechanics and engineers – protective to the point of prudishness of displaying any part of their machine to the outside world – would let their guard slip. When they did, Spalding pounced.
So why did Honda elect to use an engine layout which is blamed for causing Ducati so much trouble? And how does Honda make the layout work where Ducati have continued to fail? The first question is relatively simple to answer; the second is a good deal more tricky.
It is hard to believe, but it has been eight years since Valentino Rossi raced a Yamaha in liter capacity in MotoGP. Without even getting into the 800cc era that started in 2007 and ended in 2011, it is safe to say that a lot has changed since Rossi’s 2006 Yamaha YZR-M1 and the still unofficially debuted 2013 Yamaha YZR-M1.
While we already have a pretty good idea what was under the fairings of Rossi’s 2006 M1, since Yamaha Racing made detailed high-resolution pictures of the machine publicly available, what lies beneath the fairings of MotoGP’s current crop of prototypes is a closely guarded secret.
That secret must not have been guarded closely enough though, because the eagle eyes at GPone have gotten a photo of the Jorge Lorenzo’s M1 in the buff, and the Pride of Iwata has some interesting secrets to share with us.
Using a sole Aprilia ART racing machine last season, Paul Bird Motorsports is looking to double-down with the Italian V4 power plant, though for 2013 the British team will split its time between continuing to develop the Aprilia ART with Yonny Hernandez on-board, as well as developing its own racing platform for Michael Laverty.
Building the PBM-o1 with the help of chassis-builder GPMS, PBM will have Laverty also ace with an Aprilia RSV4 engine between his legs, though the rest of the machine will differ from his teammate’s more “factory” machine. Teasing out the first pictures of the PBM-01 chassis by GPMS, Team Principal Paul Bird has teased out some pictures of the team’s new GP chassis with the V4 motor mounted.
While the 2013 Aprilia RSV4 Factory APRC may look like the same dominant superbike that has been blowing the doors off at bike shootouts, but the company from Noale has made some subtle changes to its V4 street weapon, the most noticeable of which is a three-level dual-channel ABS system from Bosch. The ABS unit can be completely disengaged, should a rider feel it necessary to retain the ability to lock-up the newly added Brembo M430/M50 calipers (the same brake calipers as the Ducati 1199 Panigale), and brings the Aprilia RSV4 in-line with its other liter-bike competitors.
While Aprilia could have stopped there and called things a day, the Italian brand has made further changes to the Aprilia RSV4 Factory APRC’s stock engine placement in the chassis, as well as other refinements in the RSV4’s exhaust and ECU. The result is a lower center of gravity, and a mild boost in peak horsepower and mid-range torque, which brings the revised RSV4 Factory up to 181.4hp at the crank and 86.3 lbs•ft of peak torque @ 10,500 rpm.
Speaking of triples at INTERMOT, Triumph is debuting the 2013 Triumph Street Triple R at the international bike show in Cologne. Using the same 105hp 675cc three-cylinder motor that we know and love, Triumph has revised the Street Triple’s chassis for better handling, and in the process dropped up to 13 lbs off the machine (403 lbs, fueled up and ready to ride).
While the motor remains untouched, Triumph did re-work the exhaust system, reportedly to help meet noise and emissions standard, but the design also helps the Triumph Speed Triple with its mass-centralization. Besides looking the business, the 2013 Triumph Street Triple R comes with switchable ABS as a standard item, as well as an engine immobilizer (also standard). Rounding out the package is a two-year unlimited mileage warranty.
We have shown pornography CAD renders of the Ducati 1199 Panigale sans fairings before, and immediately heard office doors around the nation close shut while trousers were ruined. Showing off its frameless chassis design, the Ducati 1199 Panigale is perhaps one of the most intriguing motorcycles to see without its bodywork.
Perhaps losing some the elegance of previous Ducati models when naked, there is very little free room between the Panigale’s 1437mm (56.6in) wheelbase. With the Tetris-style fitting of pieces together into the Panigale’s monocoque frame, there can be little speculation as to why the 1199 features such a large and comprehensive fairing.
That being said, when the Ducati 1199 Panigale is in the buff, it makes for some good art. But just remember: every time you masturbate, God kills a kitten. Please remember the kittens as you click through to the full-size photos after the jump.
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.
Being sure to keep the fairings on the Ducati 1199 Panigale fastened at all times, we have very little insight as to what Ducati’s new chassis looks like underneath its clothing, and after hounding Bologna for the past few weeks over the issue, these four renders of the Panigale’s frame are the best we can muster for our readers. The black background makes the black frame components hard to see, but the CAD drawings do provide at least some insight as to how the 1199 comes together. If the Panigale goes as well on the track as it does on the spec sheet, you very well could be looking at the future of production motorcycle chassis design.
