I know that this has been discussed before but I can't find it with search - I know that the vanishing point is the point at which the road disappears and you can use the way it looks to judge how sharp the corner is going to be but I dont know how to use it... advice would be really useful

I am currently being fooled by chevrons - when I lived in Devon and Cornwall, if there was a corner with chevrons that meant it was a really sharp corner! but here up country it apparently means there has been an accident on the corner!! so some corners have chevrons and are just gentle curves - others have nothing and are actually so sharp I have nearly ended up in the hedge!

Any body feel free to correct me on this...

as I understand it when going into an unknown corner you study the point at which the two sides of the road converge.. if this point moves into the bend the expect the bend to tighten..
if the point moves to the outside of the bend then expect the bend to open wide....

Heres what I found:

Easy to exercise: take the wider possible position on the outside of your lane (right for left corners and vice versa).

This position will give you the max vision around the corner.

Now look at the vanishing point (where the tow sides of the road seem to touch in your vision- red arrow): this is your advanced scout telling you surely how the bend is going to be and the speed you should use.

If the vanishing point comes toward you, reduce speed and check


gear, when it goes away from you increase speed (and check gear).



Ideally the VP should move at your speed keeping a constant distance from the approaching bike. Now you have (before any commitment) speed and gear under control and from the right position you can see the corner opening.

Now you know traffic conditions, road conditions, and surface conditions. Now you can push the bar and initiate your cornering. Try to go a little further into the corner before initiating steering. You will see that all operation comes now into play in territory that your know.

Note that it's not /allways/ a good idea to take the widest possible position you can on left handers to get the best view... as a car/truck may also be doing the same thing coming the other way, but they are a bit wider and a lot heavier than you Neutral.

Otherwise, basically, as has been said: Vanishing point gets closer to you, slow down; Vanishing point moves away from you, you can speed up.

In addition to that, try and deliberately look further down the road if you can see, the more you know about what the road's going to do in advance of getting there. Easy to say, but it's remarkable how easy it is to forget to do it.

Wouldn't that mean they would be on the outside, away from the center line? (because it would be a right-hander to them)

No, they are more likely to cut the corner than allow themselves to run wide on right handers!

Ok I klnow I am being blonde here but huh?? if the point moves into the bend?? out side of the bend? what does that mean?

vanishing point comes towards you or goes away - surely if it goes away you are going backwards??

Im hoping this is just a terminology thing but that makes no sense to me!!!

No, it simply means if you can see less road ahead as you drive through the bend, it is tightening, and if you cansee more the bend is opening out.

Jinx, theres a picture on the page on the link I provided earlier which helps when you read the suporting text.

Good quote from the page;

Quote:
Why do we buy bikes that can lean to the extreme, why do we spend money on efficient modern tires with incredible grip…and we do not take the advantage of all these tools with a good training?


This is also covered in Motorcycle Roadcraft, which is a dry read, but good stuff all the same.

just a point which may help chevrons do not mean the corner is a sharp one, they are just there to tell you it is a bend they are normally found after a decent length straight or in a badly lit area.
in germany they have seem to have a system of coloured chevrons black and white mean a corner, red and white mean a sharp corner i think we could adopt the system here
i use the vanishing point quite a lot when travelling fast in an area i dont know, but i would not rely on too much if in doubt just slow down as the vanishing point does not make allowances for oil/gravel /horse shit on the road
heres a good bit of advice i learnt:
when aproaching the brow of a hill and you are unsure which way the road bends at the other side, if there are street lamps on the right hand side of the road then the road will bend to the left and visa versa................ just have a look next time you are out
regards
chris

Also applies to trees, walls, power lines (sometimes).

The spacing of the white lines also gives you information - wide spaces, it's all fine, short spaces, there are hazards about. That the rough idea, anyway.

Sorry, yes, ok not doing the same thing, but plenty of people do cut corners, which is what I was warning off.
