Three Points or do a Course

[dainesefreak]

I see that's the problem. There are ops you can have now you know.

To be honest, I think I have a fair point and you know it. Why upgrade?

[Walloper]

I'm changing from a Sprint ST to a GS1200R.
I don't know if it's upgrade or not.
I have had a good 'shot' on the GS1200R and like the handling characteristics.
And I carry a load of shit when touring/shopping.

Your point is what?
The bigger the bike the faster you go?

I like to assume that the combination of Selected Gear & Throttle Position determine how fast I go.

But you may join the ranks here and disagree with that.

Coz the mass is more doesn't mean it's velocity is increased.

God.... Not more physics. It's too early.

And where in the guide to posting at BCF did it mention that you are not allowed to obey speed limits?

My point is mere conjecture, with which I see you are well versed. Have I mentioned you not obeying the speed limits?

So now I'm predictable! I can't see this relationship lasting.

map old fruit.
Calibration does not mean accuracy.

calibration

n : the act of checking or adjusting (by comparison with a standard) the accuracy of a measuring instrument; "the thermometer needed calibration"

You will have what's known to the informed among us (not necessarly you) a value of 'Tolerance'.

Not error.
Tolerance.
May seem the same thing to you mate but they are worlds apart in real life.


Here's some referance for the others:

stinkwheel, you say, "The only situation I can think of where it is appropriate to lock the wheels is when driving in snow."


When the wheels 'lock' the friction between tyre and road surface has been overcome.
Because of this there is no longer any effective deceleration from braking and one is solely relying on wind resistance.

On any surface this is true.
You will continue at the same speed and in the same direction until a force causes change in that state.
ie hit a wall, a car of a farmer's field.

ABS works on the principle of Cadence braking.
Which slows a wheel until it just about STOPS then releases the brake before the wheel locks.
This can reduce stopping distance in some circumstances but ultimately it allows a vehicles lateral direction to be controlled too.
(Or Steered)

For example.
Articulated trucks commonly suffer from the effects of wheel lock and jack knife. Where the trailer continues past the tractor when the brake is applied.
This is due to weight displacement on the axle and other things.
But when ABS is fitted this will not happen as the trailer brakes will never lock the wheels so the vehicle can brake in a straight line.

Most vehicles are fitted with a valve between front and rear brakes which senses weight shift and limits applied pressure to the rear brakes. By pass this valve and you will lock the rear brakes almost every time you brake.

I may have missed a few points or details but the facts can be corroborated.
I do not know how much corroboration it takes at bcf as no amount of sound evidence can convince some folks.

I'm off to the P.O. but will check in later.

Be kind to each other.
And to your patients Stinky.

Yeah, but in snow, you are driving on top of it. If you lock the wheels, they wear down through the snow to the tarmac underneath which has a far greater amount of grip.

Obviously only works in certain depths of snow, but it does work.

As far as speed limits and stopping distances go, I'm troubled by the mass generalisations and outdated rules.

The stopping distances quotes in the highway code come from the old days of drum brakes and old tyre technology. As often demonstrated on a variety of motoring programs, moden cars on modern tyres can often pull up in about half the recommended distance.

Equally, some people have vehicles which would be doing well to pull up inside the ageing stopping distance, thanks to crap tyres, faulty (or just poor) brakes or various other mechanical maladies.

I'd like to see traffic prosecutions taking more into account than a simple 'you were exceeding this limit'. Say I'm out on my sportsbike on a nice sunny day. My brakes are about as good as brakes get, my tyres are sticky as hell, and I'm relatively skilled in bringing my vehicle to an abrupt halt. So I'm doing 35mph? Big deal, I can haul this puppy up in (say) a third of the distance that the G reg Golf on remoulds behind me can.

Likewise, when its wet and I'm out in my Laguna, I tend to drive below the speed limit. Not for visibility reasons... I do it because I know my car has utterly shite tyres and is really easy to lock up under braking on a greasy road. So as soon as the heavens open, I'm the queen of stopping distance since I have no desire to slither uncontrollably into the back of the vehicle in front. 35mph in that 30 zone? Maybe not.

What's my point? I guess I'd like to see some leeway given due to the performance of your vehicle. Top Gear not so long ago showed the SLR (I think) stopping from 120 in the space it was supposed to take it to stop from 60. If the speed limits are there largely because they want you to be able to stop quickly when faced with a potential collision, then the speed of stopping should be more relevant than the speed of travel.

Next he'll be telling you he wants a bigger bike because it's easier to stick to 30mph on.

Did they elso tell you that a kitten dies everytime you break the speed limit?

Bendy: welcome.

I think I posted waaaaay back that the ‘Old Stopping Distances’ have not been changed due to several conditions:

For those who joined us after the break:

“In addition:

Over the years "stopping distances" have been argued as no longer appropriate for today's modern "high tech" vehicles, often equipped with sophisticated braking systems and on board computers

But not everyone drives modern "high tech" vehicles
Picture the driver with a highly modified 10 year old vehicle
Fitted with a state of the art music system
And a state of the art lighting system: often underneath the car
With a braking system that uses 10 year old technology
Driven by someone with 10 months driving experience

That's why "stopping distances" haven't attempted to keep up with technology.”
I don’t believe this statement got much of a root in the dense woodwork here.

You are not helping me to understand your side by insulting me.

I do read and understand your points.

I do not agree with all of them. My right.

I don’t think there is much you can say about a system which compensates for the ‘errors’ tolerated by modern vehicle manufactures.
The 10% error is rather a lot.
We have speedometers and all that electronic wizardry on board our vehicles for decoration and ergonomic purpose.
It’s got nothing to do with the fact that as Homosapiens we are shite at judging speed and are forced employ intricate distance/time machines to aid our instinctive perception within our suroundings.
We, as God or whatever made us, were never designed to move at much more than the speed of a man running barefoot. (Olympians and Scouse/Weegie shoplifters excepted.)

Our skill at judging speeds much above that has to be learned.
Some learn faster than others. And some will never learn. Sadly.

My trivial asides?

I started the thread with a statement about my speeding ticket and results of the corrective measures offered by the police.

I do believe what was pointed out at the workshop was meaningful and not brainwashing.
But as is the norm, as I mentioned in my intitial post, some at bcf are anarchists bent on revenge and cynical retribution against any and all kinds of authority.
Who can’t even read the letters on their screen .


If it wasn’t for people measuring things and learning from the mistakes of others we would be extinct.
Natural Selection Law.

It takes legislation to keep fools alive.
Personally I don’t care if one guy wishes to leave us all in a hurry.
I just hope his family and friends are ready for his off. (and hope I owe him money.)

Mr Jamez:

Did they elso tell you that a kitten dies everytime you break the speed limit?

I’ll give you their contact details and you can advise them of that one.

Come on, he is obviously trying to wind us up as he often does.

Leave him alone.

If he really does believe in what he was told then god help him and those on the road around him.

All the best
