For me, I think it it comes down to risk vs reward as opposed to ball size. Of course I could just be rationalizing this as a thought to make me comprehend racing. And I do believe that smart balls will win out over big balls most of the times...use ovaries as a reference where needed...lol
Thus, EBD was calculating his risks (crashing) vs his reward (keeping up or making time) with each bike. At some point in his career, he changed the formula a bit and the sum had a different percentage through a particular turn.
Z3n, I think that with the speed and horsepower of todays bike, you also have better equipment to better handle those power and speed requirements e.g. suspenstion, tire width, compounds, thereby making it managable to make those turns.
Compare if you will, a superbike of EBD's era was a 1025cc beast, with as much weight if not more in some cases, tube frames that required plates to try and make them stop wobbling, and tire sizes half the width. It made it interesting to say the least. I remember riding a Z1 900 cc superbike that was fast but when it topped out, it would wobble so bad it would actually tankslap, all while just going straight...think about racing something like that!

and know that the guys bike next you does the same thing...better get those Kosman stiffeners! huh EBD?
anyway, here are some pictures if you guys will oblige me, showing the changes in racing equipment over the years, but riders are still riders throughout the eras and will compete!
a Jawa road racer
grid at Daytona in 73 - Kenny Roberts standing up
Eddie Lawson on 50cc or 80cc bike - CHECK OUT THE BAR ANGLES and legs INSIDE the fairing! and the racing boots lol
AFM Fast Guys - My hero Jon Woo
Harry Klinzmann
The factory badd ass bike at the turn of the 80's before they said they were too fast and went to 750cc for superbike limits
Eddie Lawson getting the most out of it
The grid at Laguna Seca do you know who they are?

No fair tellin EBD
one of the Honda "golden boys" (blonde) of the mid-80's Wayne Rainey, anyone remember who was the other?
Last weekend - Elena tearin it up!
hrmmmmm risk vs reward with a miscalculation thrown in
But regardless of the era, it still comes down to 2 racers competing, and the one who manages their ride best (equipment being the same of course) will be the winner.
pictures are from 4theriders, superbikeplanet, and I don't remember, but thanks for archiving history and memories for all of us!
