I'd like to stand up on the pegs on my bmw but it will be only further to fall.

Tiggs, it's not fact, it's a common misconception. Equal amongst myths like KTM's are unreliable and girls can't ride motorbikes.

Total COG goes upward, but because the riders fulcrum point is lowered and leverage is increased , the rider has more control of the bike. At this point we should ask an engineering type to draw some pictures

I don't really get all caught up in centre of gravity nonsense, you're constantly adjusting the body language anyway so to say you should stand or sit is a bit silly really.. Weighting the pegs is an advanced technique? When I started riding dirt I was taught to steer the bike almost exclusively by weighting the pegs, with very minimal upper body input. I find it makes a huge difference to the amount of traction you get - infact some terrain is damn near impossible to ride if you don't.
Say you're riding a steep clay cross slope on single track and you need to turn a hairpin back up the hill. Without weighting the pegs correctly and riding outside the bike you won't be going very far!

Deferent on a motorbike I guess

And since when did your opinion become fact?

How often do I need to change the BMW air in my tyres and where do I get some for a reasonable price?
Please dont be a wanker! You missed the point!

I said this is NOT AN OPINION, it is a fact! So it's not my opinion or anyone's opinion it is the science of gravity.

Tiggsie, I weep for you.

Also, I would be very interested to hear which other forums are having a discussion on "CoGs" and "weighting the pegs".

AFAIK the only thread about that, running at the moment, is on a Strom-based forum.
Having an interest in that thread, I went back and read through it very thoroughly.
Nowhere did anyone state that what we loosely call "weighting the pegs" made no difference.
Possibly someone reading through the thread at 400 words per minute might have got that impression ~ but a careful read shows that was not what was actually said or intended.

There, the question of "CoGs" was rather more entertaining . . . if you like being entertained by a lot of people at cross-purposes, owing to some failures to recognise what engineers mean by the term.
And that confusion seems to be raising its head now in this ADV thread !

Alas, the problems that come from misunderstandings and poor communication . . .

* Matt D is expressing things very well ~ and I like his term "riding outside the bike", which is a much more meaningful term than the traditional-but-sloppy "weighting the peg". Good onya.

Sorry Doc AT I should've realized by the amount of posts you have to your name that you are an expert. My apologies!

Agreed. Well said.

What about this bloke?



Is he lowering his C.O.G.?

suspension?

does the perceived/actual increase in control purely depend on the CoG or would it also have something to do with the fact that you're immediatley adding in your legs as another level of suspension...

And there is a good reason for that

It comes as no surprise to me, and,without a doubt...... the vstrom should be at the start- in the lead- and vstrom still going strong at the end [and way beyond].

It is also known the only way to ride a vstrom on the dirt, fast, is standing on the pegs. If perhaps it needs to corner, weighting the pegs and sliding is an essential survival technique.

All thought of COG , fulcrums, 2 COG'S or otherwise should be absent from the riders brain.

Lowering th CoG is really quite useful when riding on dirt. I've found the easiest way is to lower your tyre pressure, thus dropping the height of rider and bike. Easy. But wait, there's more, take the wheels of your bike completely and you have lowered the centre of gravity even more.









Who farted?
