<div class='quotetop'>QUOTE (Arrabbiata1 @ Apr 30 2009, 06:17 PM) <{POST_SNAPBACK}><div class='quotemain'>Exactly - it doesn't... you say this class is in a catatonic state, I'm not so sure what you mean other than the confusion and directionless course that Dorna have charted, but I certainly miss the catharsis of the 990's. There may be more precision involved in piloting the and plotting the perfect parabola, but it can be boring as .... to watch someone inscribing the perfect race line..If it has to be four strokes, I'd rather a mountain of torque as a medium, an excess of power, and the glorious chaos of the late apex = 990

What makes you think that as soon as the 990's would be reinstaed that any of the factories would use the old engines? Since the end of the 990 aera electonics has evolved imensly and smaller engine with less rotational mass has proven a lot faster in the corners. They would work like hell to get the best from both worlds. Fast entry, with little room for alternative lines, and controllable power out. And finally excessive power on the straights that would be for little use.
If they could make the bikes faster the old way then fine, but they aren't. It was a period they excisted but it's gone and will never come back. To blame it on 800's is just an excuse, it's the aids and general knowledge about making bikes faster that has evolved way past that point.
I'd compare it to the old rally cars from the 80's. Fun cars to watch with +800hp and <u>way </u>slower than todays 300hp cars.

If the 990s wouldn't reemerge faster than today's 800s, why did they decide to cut displacement? Why does any series cut displacement?

The 990s would probably be much faster especially if they added more fuel. I've said it once I'll say it a million times more, the lack of fuel is what's causing cornerspeed to be the fastest way around a track mainly because it saves energy.

The faster you go through a turn the more force you need to turn a bike, often the force must be applied for a longer period of time as well. Maximizing the amount of time a bike spends on it's side is inherently slower b/c the bike can't be decelerated or accelerated.

^^^^This was the predominant theory behind the move to the 800s with 21 liters of fuel. Unfortunately, they had no idea how much development could be done with tires and weight distribution.

If the 800s did prove to be faster, the manufacturers would continue to use them. New manufacturers and privateers that can't afford to make 230hp out of 800cc could make larger displacement bikes while they develop new technology.

BTW, the handling capabilities of the 800s have little to do with reciprocating mass. In the 990 era as much weight as possible was hucked over the front wheel to keep the front wheel on the tarmac during torrid acceleration. The 800s don't have nearly as much torque and even less fuel so a more evenly balanced bike can be constructed without losing performance in a straight line.

Good analogy. But I'd sooner watch a +800bhp Audi Quatro from the '80s with Blomquist at the wheel than today's faster 300hp cars..actually I'd be equally satisfied watching Roger Clark race a Ford Escort Mk.1 in the 1970's but that's by the by. It doesn't bring 'em back, but then it doesn't stop me eulogising either - and it's the same for the 990's. Perhaps that's why I derived more pleasure watching Sheeny race a Classic Manx Norton after the British GP in 2002, than the actual main race.

Who said anything about reinstating the 990's? What made you think I thought that the factories would use the old engines?...when did I mention straight line speed. Sea air gone to your head?
Talk to any dirt tracker worth his cinders, and they'll crack a toothless grin, and cackle something about excess power on tap.

I'm fully aware of the technological evolution of this series, as I'm also aware of the devolution of it's entertainment value.

Why preach Babel?..you're not saying anything we don't already know, or haven't discussed before. Sure, I'm not alone in my lament for the 990' s but I'm not the only one to mourn the loss of the 500cc class or the 250's come to that. You want to go over old ground again then let's go up that well trodden path..but it's a tiresome ramble.

Two years ago this class was emasculated to 800cc. This horsepower reduction was an attempt to slow everything down, precipitated by the tragic death of Daijiro, and ironically HRC's designs on a capacity reduction. Of course, during testing, before one of these mini-bikes had even been raced in anger- if that's possible- it became immediately obvious that it wouldn't be long until they were inside the 990 lap times. So it didn't work, the electronics began to prevail. A prototype class predicated on the rise of the machine - its mission to exterminate any freedom and expression on the racetrack and to subjugate by sensor, sacrificing individual control by means of electronic implants. 'The Late Apex' has died an artistic death, the functional future is subservient obedient predictable monorail. So safety aside, it was also to the detriment of entertainment...the bikes began to evolve around other things that made them go faster...which weren't in the engine department anymore. The costs have spiralled...the much mooted standard ECU, two day race meetings, one bike team and outlawing of carbon discs are all moves to reduce these and also engender closer racing. To redress the damage that has been done.

I don't understand the point of your response Babel. You are one of - if not -the most knowledgeable contributer to this forum on technical matters, but like our other resident 'engineer' you are sometimes intentionally contrary and condescending.

Your recent demolition of BM's absurd drivel on the subject of gyroscopes and gps systems was one of the most entertaining threads I've ever read on here. Don't direct it at me.

Question Babel, now that I come to think of it...these systems are now so sophisticated that they can determine the optimum/viable speed that Casey's GP9 can almost autopilot around any given corner. I tend to agree, this technology is irreversible, I don't think that's what you want or that's what Dorna want to see - but it's certainly what the MSMA are intent upon. It's like excessive sampling in music, blanket CGI in movie making, or photoshop rendering three generations in the dark room suddenly obsolete. Why should I be afraid to express my luddite purist view of racing, and why shouldn't we be wary of technological impositions? - because IMO that's what it is tantamount to.

You claim you didn't say you expected the old 990 engines back, non the less it's a fact that the mantra of the traditionalists of this forum has been "bring back the 990's". Without any other spesifics there are no other reference than exactly that: The old engines of '06.
You say you are aware of the progress, but still go in the trap of comparing the 800's of today with the '06 990's when it comes to speed, safety and entertainment. Witch is it? The 990's of today would be even faster and more dangerous and most likely just as boring as the 800's. If you followed motor sport the last three decades you must have seen that they have all fighted the development with restrictions to power. WRC, F1, 500GP, motoGP... and the cost has spiraled indepently of new ruels or not in a constant spiral.
You like the analogy of the '80's Rally cars yet fail to see that even when the modern WRC cars are way faster they are safer to drive than the old monsters. And I'm not talking about teh safety cage.
I'm not a fan of 800's as they are today, I just don't understand the black and white sides people here take. It's an illusion, grow up and face reallity.

It is unlikely any of the current riders could have mastered the three bike configurations, certainly not to the same extent, but many of them have not had and will never have the opportunity to do so.

Wrong. As usual.

Well your argument is surely based on assumption, which is fine, but not if you're going to be selectly leaving out what would naturally follow in the reality of a development continuum. You try and build a case on the premise that the 800s should not be compared to the 990 of 06 but then make no mention of the continuum that would have followed had the sport’s rules not changed. One major reason the 990s where so close and produced such great racing was because most all the manufactures where near the same level on the development continuum. Even the true privateer team of KR was in close proximity to full factory efforts.

The big difference is not that the 990s would have stopped developing, and hence kept advancing in speed and performance as you say; but rather this all came to a screeching halt and a new baseline had to be established with the introduction of the 800s. This changed EVERYTHING! Every single component and characteristic had to be revised. Perhaps the only thing that didn’t change was the tires being round and black. This revision left some manufactures getting it very wrong (Honda, Kawasaki) some right (Yamaha), and some a mixed bag (Ducati, Suzuki). There in is the disparity of development regards to close racing and performance.

You fail to understand had the 990s stayed with us then the development cycle would have continued; the manufacture's understanding and development of it would have progressed evenly among manufactures. This is the point. Again, yes the 990s may have been faster, but not so un-evenly matched as the 800s have proven to be; and this has more to do with the dramatic change and disruption between manufactures' development continuum. Comprende?

“Grow up? Illusion”? Haha, you’re so far in an imaginary world that you can't see the mirage you believe to be truth is really just a figment of your imagination and shady logic.

You make it sound like every corner can be squeared off while in reality the majority are only small kinks, open turns or long U turns, none of whitch is suitable for any anicient point and shoot technique. To go faster in the turns has allways been the way to go faster. No matter how you angle it, more grip and more lean angle is allways a good thing. Thos extra ms they stay longer leaned over doesn't change that those parameters will allways be on the top of the list for development.
I can't see how that has changed with the 800's.

The Yamaha would be a good example of how much things changed. From '06 to '07 they did only minimal tweaks to the frame, and while it created a nightmare on q-tires in '06 it was as you said working well in '07. But the changes were hardly visible at all. Not exactly the quantum leap you argue?

The 990 area had good racing through all the years it excisted, not only the last year. I don't buy that the difference became that large due to the engines (The chassi's hardly changed at all except on Honda and Ducati. Probably not more than any regular yearly update) It's other factors that has produced the big change. Fuel limit and TC for starters.

I'll promise you one thing though, there are no pirates near the oil installations of the north sea and anyone comming within a mile would probably be shot to pieces before they knew what happened.

Look in the mirror Mick.
 
Looking at some stats and it seems to me that although the racing appeared closer on track (possibly due to Vale's notorious sandbagging on the 500s and 990s) from 2000 to 2007, the end results of the championship for the first two years of the 990s is eerily similar to the first two years of the 800s. Consider: 2002 - first to second 140 points; 2003 - first to second 90 points; 2007 - first to second 147 points; 2008 - first to second 93 points. Hmmmmm...
