ummm....ok. Now can you put all that in laymans terms so I can understand it.
I get the material, release factors, ratings etc...but in simple terms. Pretend you are explaining it to a 5 year old....that's me.
just talk to me in simple terms without being condescending (had to add this last statement cause I've been responded to before as though I'm a 5 year and retarded) so just explain the concept in simple terms.
I appreciate your effort in trying to explain it but I still don't get why on my CB1 (revs to 13K) and it's a 1990 bike with old tech, why the rear wheel will grab hold of the road at a mismatched rpm and skid a bit and yet, that "effect/sensation" is non-existent in the 919?
is it the 919s lower rpms?
is it that the clutch system is built differently?
This is re a 400 cc CB1, correct?
That is good for maybe 120 mph and weighs about 80# less than a 919 and is on a skinnier rear tire?
A rear tire that I am guessing could be old, aged out, and maybe worse yet run at a higher pressure than it should be for decent grip but enough for the carcass to still feel and be stable?
Now for some quick math.
13,000 CB1 vs 10,000 re 919
120 mph CB1 vs 140 919
For sake of simplicity, assume tire ODs are same or very close.
This means the CB1 has 40% more engine revs per mph than the 919.
(13000/10000 x 140/120= 1.4)
So to match up a mismatched engine RPM to wheel RPM, means the situation is 40% worse for the CB1.
The CB1 also has about a full point of higher static compression.
The CB1 bike is significantly lighter. (re rear tire loading to maintain grip)
The tire contact patch is smaller and if aged will also have poor grip.
(Unknown is whether this is happening while also on the front brakes or not, re front dive = weight transfer off the rear tire)
It's a blend of everything, but the short story is this:
There's not enough cushioning effect between the rear wheel and the engine to stay within the grip limits of the rear tire when the rear wheel is trying to accelerate the drive unit rotational speed - the engine unit component primarily.
(Some tranny elements are trying to be accelerated while others are trying to be decelerated.)
I know this is not as simple as you hoped, but hopefully it helps you along - perhaps even triggering more thoughts and questions.
