<{POST_SNAPBACK}><div class='quotemain'>1. Since the development of chassis, tyre, and electronic advances the advantage of v-twin driveability has been made redundant, this is shown in Hondas choice to move back to 4 cyclinder bikes. The Twins used to be the better racing machine, but not any more.
Wrong, Honda left the twin long before they used any traction control in SBK. They left the twin as they bored their long lived king of sportsbikes, the Fire Blade 900. Unfortunatly there were no defined 900 class for road sportsbikes, the blade was alone, and thereby no class to put that legend into high profile racing.
The 1000 on the other hand got it's top SBK class as all the japanese brans started to revamp their product lineup, and the rule change no doubt were pushed forward by those whining japanese companies. Who are they to dictate the rules, eh?
Wrong, no electronics are able to simulate the twin pulse operation.
Big bang configuration do a decent job but still lack a bit, and they have AFAIK problems to put that into a stret bike version anyway.
Proof: Ducati is currently competetive with a lot less horse powers, traction control or not.
<div class='quotetop'>QUOTE <div class='quotemain'>2. The reason why the diesels have an advantage at Le Mans is because the rules were written that way for political reasons, and i do not approve of this. In most of history racing classes have been defined with a capacity limit because it is the fairest way to restrict engines, it is the manufacturers responsibility to get the best performing vehicle from the rules rather than ask them to be changed.
Political or not the rules were written that way. The petrol cars are slower, ergo they must be yesterdays technology, or?
Capasity is of no use without further limiting the number of cylinders, and the type of engine used. A 800cc Vankel rotor engine would blow Ducati and the rest by a mile. A 6 cyl. Otto (i.e. the normal combustion engine) would also blow Ducati away, but they put a heavy wehight penalty on those bikes, and HONDA made sure the 5 cyl got the same penalty the second they left that configuration themselves (Those whining .......s or what ever you prefer to call Duacati today. It applies just as well to any of those companies, doesn't it.). How about turbos and blowers? They must clearly be part of a superior technology as they develop a lot more power under the
same capasity.
In other words, capasity is only one tiny parameter among a dozen that limit the power and create close racing. There is not one single good reason why that parameter should be absolute, just like there often are varying limits for weight, cylinders, air intake size to name a few.
<div class='quotetop'>QUOTE <div class='quotemain'>3. I don't believe Honda did make 6 cyclinder 125cc bikes,
You're right, I was conviced it was the 125, but that only made it to 5 cylinders, while the 250 and 350 had 6.
<div class='quotetop'>QUOTE <div class='quotemain'>but you are right that engineers have been aware of the relationship between cylinders and power for a very long time, why is it Ducati hasn't yet caught on? Except that in motogp with design freedom as it is, Ducati chose not to use their L-twin design, so even they know it is inferior.
No less inferiour than the 4 is compared to an 8 cylinder. However, other rules make sure it can't compete. Weight, weight limits, and gas tank sizes make sure of that. Even a 6 cylinder would blow the fours away. The RULES just make sure they are not competetive. The RULES make sure the fours are the best compromize, not the capacity, that is by no means a proof that it is the best configuration, it just the best (compromize) under those spesific rules.
To make a firework of a 6 cylinder engine, compact and light enough would be no match for Honda, assuming the RULES would favor that configuration. But it would drive cost up a big step, and that's another very important limitation that the organizers want to keep a firm grip on, to make sure smaller teams and companies can afford to compete. Again, fours seems to be a good cost effective compromize. But in a prototype seiris like MotoGP that shouldn't really be an issue, should it?
<div class='quotetop'>QUOTE <div class='quotemain'>4. If superbike is a market driven class then why don't the Japs just start making 1400cc superbikes and ask the rules to be changed to reflect that?
IF? don't be silly. This series is based on mass produced bikes and it's part of it's huge popularity
1400 don't get buildt because you and I wouldn't buy those monsters. Some morons by the Hayabusa 1300 to be fast but anyone (with a 600)can drive around that monster on a track.
