<{POST_SNAPBACK}><div class='quotemain'>I only take exception to using the word "drivability". I would prefer "usability". Yeah it's a stupid semantics issue, but in my mind, the most drivable bike would have 10hp and training wheels.
Call it what ever you like, I just following the standard expression.
<div class='quotetop'>QUOTE <div class='quotemain'>I agree also that Ducati does have a good chassis at this time. Those crazy Italians are obsessed with trellis frames. They didn't work with 990's b/c they can't handle the power, but they seem to work fantasticly for the time being. If Ducati don't do more chassis work, they will be slow when the power comes up.
Where's your take on that? The original 990s probably didn't have more power than the 800s and were by far much slower. Why wouldnt the Ducati work then?
This is not at all about trellis strength. They are exactly as strong as you build them and they can easily cope with double the power, with som added weight. If anything the ducati frames are AFAIK made of CrMo steel. That give the frame a very different flex from the Deltabox alu. Alu is a very dead material, small flex and even dampening that. CrMo is more spring like. But bikes need flex and how much and where is one of the huge mysteries in bike constuction. A strongly doubt they couldn't get it right with the 990 because of power, I find it much more likely that they by hard work or coinsidence got it a lot better this time around.
<div class='quotetop'>QUOTE <div class='quotemain'>If you leave physics out of the equation the 990's would have gotten easier to ride. The strain put on a person's body by exponential performance growth in the 990 class, outweighed any nice things they could have done to keep you from crashing imo. Top speed and acceleration out of the corners was the name of the game in the 990 class. You have to be a beast to decelearate and countersteer that kind of power. I'm not sure they can put power steering on motorcycles..............yet.
The power doesn't make it harder to steer, the running mass in the engine does but that's quite constant or even lighter as development goes on.
Power was not the game with the 990.
- Rossi won the title with an underpowered Yamaha.
- Last season saw the smallest differences in power, and that tells me everyone was more or less on the same power because they can hardly use any more. The powering out of turns has from the beginning been limited by grip so no added power will help there until a couple of generations of super rubber are invented.
Same goes for the strain on the person riding the bike. The strain is limited by tire grip, not by engine power. These beasts only use full power at high speed straight forward, and that's not where the riders meet the maximum strain. Braking probably better and harder with the new 800s, resulting in higher maximum strain on the rider than before.
So, to sum it up, the only reason why a 990 would be harder to ride is the added rotation mass, and while it does make a difference, there are limits to how much a difference 190cc does. Adding that the rotational mass would probably be less as development goes on, not more.
