All the replies all helped alot. Especially that there are no absolutes and it's all corner and situation dependent.
I'm at the point where I'm just starting to learn how to go faster and I really needed to know what is desired for real speed and was is just there to keep us out of trouble.
I remember my very first track day in a car taking the school. In class they say - a car will only do 1 thing. Accelerate, turn, or brake. So they teach you to brake in a straight line, finish your braking completely, then start turning.
I wish they would have just said - "fast drivers brake and turn simultaneously, and they also accelerate and turn at the same time, but since you guys are new and don't have the proper car control - please brake in a straight line, finish braking - then turn...
It really makes me wonder on a slightly different topic - why is the front tire on a bike smaller than the rear. They obviously do this so that the rear can handle more of the traction, so under acceleration - the bike is 50/50. The front gets 150lbs, the rear gets 250 lbs. But since the rear is wider than the front - it equates to 50/50. So under acceleration - the bike handles beautifully.
In a car - this would be called a staggered setup. Most BMW's would have skinnier tires in the front than the rear. For practical track purposes - it's not a good thing. It's a formula for understeer (front end pushing). BMW has spent so much energy making a 50/50 weight distribution car, and ruin it by running skinnier tires in the front. The reason is simple - insurance. When a car starts sliding - most drivers automatically lift off the gas, and get on the brakes. During oversteer situation - this will cause a spin 100% of the time. During understeer - brakes are not as catastrophic - so BMW decides their cars to lean towards understeer. Get rid of the staggered setup on your BMW - and the car handles like a dream!
What would happen if a bike - which is 50/50 in weight distribution, would also have a square setup. 190 front and rear? Then you can go in very hot trail braking into corners without understeering, have amazing traction during maintenance throttle in the mid corner phase, and good acceleration because when accelerating - the front wheel is almost off the ground anyway - so who cares???
Just asking - i'm sure there is a reason well paid engineers at Honda, Kawi, Suzuki, BMW are all down with the staggered setups on the bikes - and my thinking about it is all wrong. I'd just like to find out why
