When I got home in 88 degree weather after a 85 mph run for 1/2 hour the front was 41 lb and the rear 47.
Unfortunately I did not note the internal temps.
( 38 and 40 respectively cold ....the mechanic just filled them the day before and the TPMS confirmed that.
A softer fill would likely
a) get to the same pressure at those speeds or even higher due to extra heat.
b) run hotter
This is a general comment on tires but it applies to the Burgman as well...
-Lower inflation numbers (28-35 psi) will give you a soft, smooth ride but your tires will run hotter and your fuel economy will suffer. -
You are very likely to end up with the same pressure at speed but have more heat which is brutal on that rear tire.
The Shinko was at 41 cold the first PA run two weeks ago and it stepped out a bit in the twists.
I was taking it easy in the twists this time with only the front brake to rely on but the front stayed nicely on line tho I missed having the rear to work with. Was interesting practice and sure pointed out how useful the rear brake is especially at low speed.
For reference.
New Shinko ( bought a spare )
Have ridden this about 6,000 km
Kids - sport bike tire.
