You can get Harleys with white tyres.
But then again, on a Harley it's easy to measure the lean-angle by looking at the scratch marks on your chrome.
On another note, we all like to ride our bikes. Now, if some of us like to discuss these meaningless things - and don't fool yourselves into thinking we don't realise that it doesn't matter at all out there in the real world - where's the harm in that. How about, instead of getting all annoyed and making arses of yourselves, growing stomach ulcers and whatnot, you leave the discussion to those that might enjoy it and go out and ride your own ride? Just a thought, but hey - I'm just another idiot so don't mind me.
It is preferential to refrain from the utilisation of grandiose verbiage in the circumstance that your intellectualisation can be expressed using comparatively simplistic lexicological entities. (...such as the word fuck.)

Indeed. Talking about motorbikes on a motorbike forum... Who would have thought!![]()
Yes, the balance point will have to be moved. But not because the CoG has moved. Gravity is still acting through the same centre. It's just that there is now another force acting unevenly about the original pivot point.
There is, however, another possible explanation that means we're both right. The CoM definitely won't move but maybe the CoG does because the force of the air can be seen as equivalent to an added mass.
All this is irrelevant to a rider though. In this case the wind is horizontal. Hence, the resultant force is not helping or counter-acting gravity at all as it's perpendicular to it.

One of these is not like the other.
Which lot do you think understand the physics better?

COM and COG are two different things. They are often thought of as the same because they are in the exact same place until you add the thing that has been missed out in these explanations..... centrifugal force (CF) you have to add CF to the equation of COG, COM and wind resistance. as CF increases so does the amount of effect gravity has on the mass (G force increases) Wind resistance has little to do with cornering compared to COG, COM and CF. Total mass is important and relates directly to how much effect CF has. COM is important because it determines WHERE the CF has the most effect. Also in the equation is enertia or momentum (speed) the greater the speed or mass, the greater the CF. CF is why we have to lean our bikes to corner, we offset the force trying to biff us off by making the force hold us to the ground. our COG does in fact move, the more g force the lower the COG. our mass does not change therefore our COM does not move. but our "weight" increases with g force. This explains why it is better to weight pegs (rather than the seat) because the extra weight we gain with g force is exerted at a lower point.
i'm too fukken tired to try to explain it better and to be honest all this thinking is doing my head in. Interesting thread... time for bed.... blood is red..... my brain is dead. OK seriously i'm going insane. night night

Just one minor correction - Inertia is a body's ability to resist changes in velocity (speed or direction). This is constant irrespective of what speed is involved (but only if you ignore frictional forces).
Otherwise I agree. Especially the last bit. I'm getting a bit tired of this on-call lark. Paged at 00:30 and can't get back to sleep. Time for another attempt![]()
