I came a cropper

I don't know that's why I'm asking.
I reckon the actual weight of the bike itself would have some effect.

 

ta
bastid.

 

orignal.

 

i find the same on me glodwing...more so the front, 5PSI in it between
nice motorbicycle and falling over head shaking behaviour

but i've never had the rear tyre down to 28 to check the response

when the front is low it can turn quite sharply to follow a line

 

Since you are implying you have superior knowledge re; ZX12, you tell me.

I'd be very surprised if you could tell me the difference between
"recommended" and usable.

Do you still need to have cross ply on the beemer?

Nope you are intelligent to work it out for yourself.

Recommended:
1. To praise or commend (one) to another as being worthy or desirable;
endorse: recommended him for the job; recommended a bike instead of a car
2. To make (the possessor, as of an attribute) attractive or acceptable:
Honesty recommends any person.
3. To commit to the charge of another; entrust.
4. To advise or counsel: She recommended that we be on time.
Usable:
1. That can be used.
2. Fit for use.

No.

But for the fact that the research shows that advanced rider training is
shown to have the negative effect of increasing rider confidence, which
means the rider rides harder and more confidently, putting themselves at
even more risk of fishtailing themselves into trouble.
Or so the TAC/Monash Uni Accident Research Centre says.

Specifically rider training or driver training?

Rider.

For most modern bikes, I would consider 28 psi to be too low for
anything other than a sedate ride on a straight road. Start throwing in
a bit of speed, or a situation where handling is required, that low
pressure WILL make the bike respond differently than if set up at
recommended pressures (which in the case of the bigger sports bikes is
well over 30psi).

For any bike I've ridden - other than the little GS450 - low tyre
pressure makes them wallow.

Why do you say that 28 psi is NOT too low?

I'm surprised to hear it (I'd heard that about cars, but had always
assumed the opposite for bikes). Got a cite or do I have to do my
own homework for a change?

Hammo has this habit of asking questions to provoke debate and when he
doesn't get what he wants he'll poke and prod and poke and prod.

 

The K-bike was like that. It didn't take much of a pressure drop to make
it feel like a log on wheels.

Get it right Peter, an intelligent shit-stirrer... he drinks Coopers!

Oh! A shit-stirrer! That's alright then.

In fact they are often around the (recommended) 42 PSI mark.

Odd then that racing bikes (that surprisingly enough require handling in
more than just a straight line) have their pressures considerably lower.

You need to consider the shape (and construction) of the tyre (apart from
being round) as this also influences how the bike behaves.

Blanket rules are for people that can't handle difficult concepts and this
is truly a case of "horses for courses". I have found that PSI has less an
effect on handling than steering head bearings and the torque they are set
at.

Some people like their tyre pressure to be what the manufacturer says,
others find what they like by experimenting and others let someone else
worry about it.

Long story, but I happened to be killing time in the same room as one of
the TAC's behavioural scientists, whose work is funded by the $50
motorcycle levy. Nice bloke. Crossed a few interesting points such as
this one, and the TAC's underlying wish (and I only say wish because
it's not something they're pursuing) to be able to remove the state's
roads of sports bikes for the safety of all riders. He told me that yes,
rider training does have some benefits, but only for new riders, and
more mature people returning to riding after a long break who need to
quickly climb a few rungs up the skills ladder. Riders who do advanced
riding courses tend to have a higher risk of coming unstuck, because of
the confidence leap.
It's one of the reasons that the call to use the $50 motorcycle levy on
advanced rider training has not been heard.

Nice drop, that Coopers. But jeez it snuck up on me. That was a looooong
time ago, and I still haven't gone back for seconds.

I'm not sure of the specifics of this particular research/report but I
believe many of these are funded but the various state Governments
The researcher knows that their employer wishes to show that SPEED is the
single most deterring factor in the road toll and better skilled riders will
not have a significant effect on this .
No only by reducing the number of speeding antisocial renegade motorcycling
filth will we ever hope to save the lives of the innocent
If the researcher wants another lucrative Gov. contract he/she knows what
questions to ask and how to ask them to achieve the acceptable result.
A bit like the researchers in the 70's who when funded by the tobacco CO's
found no plausible link between smoking and cancer
