tire pressure
Denizen
the front and back tires to 30psi. Now the scooter handles very well
in corners, but with the 20psi left in the tires after winter storage
the scooter wallowed around bends in scary fashion. What a difference
a bit of air makes!
As to the *correct* tire pressure, a Transport Canada sticker on the
scooter says it needs 33psi front and back. But the scooter manual
says something like 23psi front, 26psi rear for two people on board
(I'm heavy compared to young Koreans :). For one person the
recommended back pressure is even lower. So I'm mystified as to what
the true, correct pressure should be, but 30psi seems to work great!
Do other folks have experience with scooter handling varying in
response to tire pressure?

my theory is that any two-wheeler that is tail-heavy like most scoots
should be 4 or 5 psi lower on the front tire. not sure about sport
bikes, never had one.

The first time I noticed the effect was on my 50cc Honda Express. At
25-30, it felt like it would fly off the road. Very unstable. I
thought it was wheel balance or loose fork bearings. I never paid
attention to the pressure. I would just air the tires until not soft,
like a bicycle.
One day I aired to specs and it was night and day. It was rock steady.
I had noticed on both Elite 80 and 250, that low front makes it feel
like it wants to keep turning and is reluctant to come back straight.

When I unfortunately bought a Chinese 50cc scooter, the tyre pressures were
understated in the user manual by a similar amount, but later corrected in
the manual without stating it was a correction, so it looked like a
contradiction, which of course is no use to anyone who didn't realise that
it was a correction, leaving them riding with under inflated tyres.

some manufacturers have a sticker that lists the PSI with driver, and
the max PSI, with passenger. if 30 is working for you, keep using it.

The measured tire pressure also depends on air temperature and which
gauge is used. I pumped the tires to 30psi on a cold morning near 0
degrees C (32F). Then during the warmth of the day a week later at 15C
(60F??) they measured 33psi with another gauge. Per the group
suggestions I dropped the front tire 4psi to 29psi using the second
gauge and the scooter still turns well at speed. I have noticed that
the steering is now harder to turn at standstill or very low speed,
compared to the still-higher pressure.
BTW one gauge travels with spouse in the car and the other is at the
house, so both are not always at hand. Thanks to the group for your
suggestions!

You might get better handling or at least think you do if you skip the
tonic and take the B.Sapphire straight.

I have warned people about Chinese valve stems for 3 years now, They last
about 1 to 2 years before failing.
