Backing it in is a very useful defensive technique and also a good way to make passes because you can be late on the brakes.
Even Rossi has quoted saying that he doesn't slide anymore because the tires are so good now that you end up going slower if you slide around. But if you're leading and someone is trying to pass you, then getting the bike sideways (perpendicular to the apex somewhat) covers more ground and can deter a rider from taking a certain line to pass.
But I'm not too sure on the debate of whether backing it in saves tires or eats them up. I've always thought it saved tires because you're not riding on the edge of the tire to make a turn, rather using wheelspin and steering forces to get around.
I didn't mean to imply that backing it in is the faster way around. I know it's the slower way. What I was implying is that you CAN back it and still be fast. Elias proved that :)
Onto the 800s:
The 250cc riders aren't going to have this huge advantage that some of you believe. They still have to deal with 4-stroke characteristics like engine-braking. Sure, the transition from a 250cc 2-stroke to a 800cc 4-stroke is going to be less difficult than if the rules never changed at all, but not to the degree that I'm reading here.
I do see the the GSV-R (finally) and the Ilmor/Suter X3 doing well because of their use of pneumatic valves. The high(er) revving bikes will take full advantage of that F1 technology. Hopefully, we'll see Hopper on the podium for once.
To sum it up:
GP racing is NOT going to be turned upside-down because of lower displacement and slightly altered power curves. And 250cc riders aren't going to have it any easier, it's just going to be a bit less difficult for them. That's it.
Here is my take on the 800s. Removing 190ccs is removing a LOT of torque from the bikes. Torque matters a lot when you are carrying extra weight. It's what gives you good drive out of the corners.
The 800s will be down on torque by a good margin. With lighter cranks, that will shave even more torque. Now, slap a 105lb rider vs a 150lb rider on the same bike and the advantage goes directly to the lighter rider.
Pedrosa, Capirossi, Stoner, Melandri. They will all have an advantage. I think MotoGP needs to implement a minimum rider/weight restriction to insure the BEST riders get on the track and not just the smallest, lightest....
Otherwise you'll see no more AMA/WSBK/BSBK, etc riders making it to MotoGP unless they're tiny. Like DiSalvo....
