RE: [ST] for Matt and Richard - tire width & cornering

["Heyer, Matthew A." <mheyer@xxxxxxxxx>]

(Didn't I tell myself that I would drop this and get back to
work....maybe why I'm still at work approaching 11 hours and
counting......)

Yes, theoretically with the different widths of the tire, the arcs are a
function of the tire width, with the rear being the wider and thus
turning in faster at a lean.  But practically speaking this is very
negligible for the size of the arcs being dealt with.

The "skid-steer" is also offset by the front tiring doing the turning
and thus also technically doing a little sliding as the forces push the
tire off-line.  So no compensation by power being applied at the rear.

I'm done....back to work to get out of here and have a beer sometime
soon.  Ahh, and just to thing - I can do it all over again
tomorrow......  Damn shouldn't have come back from Puerto Rico.  Warm
weather, on the client's dime, and people look at you weird if you work
past 5:00 (Don't you have better things to do!!)

Pardon me.  If the front and rears are different widths, there will be
an arc change with lean.  The rear moves inwards faster than the front
assuming rear wider than front.  Also, if power is applied to maintain
speed (who in their right mind would accelerate while leant over? ME!),
it will be off-centre and produce an element of 'skid-steer' like
tracked vehicles use.  This would be in the opposite direction to the
turn.

The lean will not affect the arc of the two tires.  The path,
regardless
of the lean, will be the same (if your front tire follows a said path,
the rear will make its own path due to the length of the bike and the
path of the front tire).  Now sliding the rear out will change the
path
of the rear...try at your own risk.....
