MM93的問題應該在於車子設定被亂搞
設定, 我不懂. 上站 Le Mans 本田大敗, 我曾讀到一篇文章, 那時有摘錄以下幾句: ( 內容挺催眠的 )
Marquez is famous for his hectic braking style with rear wheel coming up and the bike hunting from side to side,
then nailing the apex, lifting quickly, and accelerating away.
The Honda men brake late and very hard, get the bike turned, then lift and accelerate.
to benefit from high speed all the way through the corner, The Yamaha men must be gentle with tires.
That calls for softer spring and damping rates, and for earlier, less severe braking,
and above all, for smooth transitions from braking to turning, from turning to acceleration.
The Hondas need a stiffer fork set-up
that can very quickly accept 100 percent weight transfer to the front without bottoming.
The Yamahas, by contrast, need maximum corner grip,
and that calls for soft spring and damping rates all the way to the bottom of the fork travel.
The last thing they need is a sudden stiffening near the bottom of fork travel,
for this is where the bike rides in mid-corner.
Yamaha corner speed depends upon keeping constant load on tires.
Now we can see that the Honda riding style,
combined with a 36-degree track temperature rise, could push the tires to the edge.
Crutchlow at the Jerez Monday test compared the present Honda swingarm with a new version,
intended to improve grip in an area where the Honda is lacking—in long “hanging” corners.
In other words, in bigger corners, the Honda men cannot use their normal stop/turn/go style
but must match the Yamahas in edge grip for long seconds.
I am guessing that the normal Honda swingarm is a bit stiffer than Yamaha’s,
and that the new part is intended to make life easier for the tire edge during those long seconds.
I think this is definitely part of the reason why the tires were working for Vale in Argentina and not for Lorenzo.
Is it possible that the amount of time he spends on the edge of the tire
was working against him on a fairly abrasive surface like Rio Hondo?
The tire edge, being a mass of rubber poorly supported by the fiber carcass, flexes a lot and so heats up rapidly in use.
Simple thing is, they gave me finally a set of front forks that allow me to brake where I want to brake.
Basically, it’s to try to stop deforming the front tire.
You’ve got more limit to play with as you go into the corner.
Instead of being on the limit and it collapsing completely flat, you’ve got more leeway to play with it a little bit.
Which, with a Yamaha, gives you confidence to release the brake, which (keeps) corner speed.”
Lorenzo’s corner-speed style requires keeping the fork tire-preservingly soft pretty much to the bottom of its travel,
because that’s where the bike is riding in mid-corner
(remember, maximum cornering doubles the load on the suspension).
A fork that soft is going to bam down on its travel limiter as Smith brakes in his preferred style,
and that makes the tire move, spoiling his corner entry.
The new fork internals can handle Smith’s higher rate of forward weight transfer during braking,
so he arrives in control, rather than fighting for it.
