The Superbike never ceases to amaze ever. High lai are planted when someone threatens to usurp the right of first refusal Infront towards any form of derivation of the series, on the other hand, when someone goes away in a, well, surprising, even iperspecialistico model road … all silent .
CHANGE OF DISTRIBUTION
If someone had escaped yesterday during the launch of Aprilia Alitalia, someone has “let slip” a trivial news item from the technical point of view, like the fact that the RSV4 SBK 2010 will have command of the distribution gear. You read that right: by the two chains, into the gears, as required by Regulation Superbike technical point 2.4.8.
Camshaft control system must remain standard, unless there is a kit for free sale. How to say the bike must be completely standard, not a bolt can be changed. Unless, of course, there are no parts for sale aftermarket .
But why ‘?
Still leave lose these considerations, and let’s a question: why go to work on one aspect – the command of distribution – which does not seem to have caused reliability problems, which is hardly the basis of performance problems, which, in short, where he was standing there looking pretty? The question arises, as he said Lubrano. But the answer, thinking it a bit ‘. It is an answer that probably will not like at all the boys to Infront.
DIMENSIONS OF THE QUESTION …
But let’s go with order: as we have said, is not the command of the distribution the limiting factor of the maximum speed reached by the RSV4. The manager was probably trying nell’alesaggio, which with its 78 mm is a bit ‘limited compared to that value – over 80 – with which the motor was born, before the cycling considerations and definition of the intake ducts that There have been repeated ad nauseum at the time of presentation took over. The control of distribution, however, is responsible, at least in part, of the dimensions of the engine. On matters of economic efficiency, the Aprilia V4 cylinder banks is identical wording: it produces a unique piece and mounts, turning on both banks. Logical and effective solution, but it has a consequence: two chains of distribution on both sides of the engine.
MA E ‘GIA’ IN ITS COMPACT …
Never mind, you might say: the RSV4, his is one of the bike more compact market, thanks to the engine, that with the narrow angle V comes to be moved into the frame so as to vary the placement of its center of gravity of around 5%. It ‘true, when it comes to road bikes. But in the case of the prototypes, the question changes: a GP, if provision is made – often the bikes do not allow private part of those rules – the engine may be installed by changing the CG position of more than four times as much .
MOTOGP DREAMING
A moment — I can almost hear you say – and what enters the prototypes? A factor. For those who had lived under a rock in recent months, the fan MotoGP Regulation 2011 should be possible to run engines loosely derived from the series. As it happens, with a maximum bore close to that with which he was born the RSV4. Certainly, there remains the problem of aspiration, although perhaps to circumvent not having to submit to the restrictions of the approval of roads.
So? So here is the distribution gear, which reduces the overall size of the motor – the thickness compared to the chain falls, and in the future could be taken on one side of the engine – to, well, testing focused. To obtain an engine more compact and therefore more suitable for use in a prototype bicycle .
DEVELOPMENT ALONG THE RULES
The Superbike a test for MotoGP? It would be ungenerous to Infront and the league itself, but if so – and we have no certainty, of course – then, that someone running for cover, because at the end of the Aprilia has not done anything contrary to the regulation: that, however could only be the start of a development based on the folds of the Regulation (see the F1 with the ugly history of the speaker Brawn GP 2009), and the kit was created specifically for the inevitable increase in performance, cost … and as consequently, has the decline of spectacle and the consequent withdrawal of builders and teams.
The solution is simply to draw up a regulation which rejoined the series that run the bikes in Superbike. You will see that so, some temptations are not to anyone .
