97 sport 1100 tire pressure?

Fill your cold tires to a pressure, write it down. Go ride for at least a half hour through hiway and twisties as best you can. Stop and check the pressures again and they should be within 10% of your initial fill. Adjust accordingly.

I've had mine all over the place. It doesn't seem to make much difference. I've run as low as 24/28. In both the Tail of the Dragon and Running 90+ down the Idaho panhandle between Glacier and Spokane, they were good at 28/30. But lower pressure had a noticeable increase in parking lot effort, so Iv'e kept them at 35 both ends since and it's...still fine. I haven't ridden these Dunlops hard yet but I'll set the pressure for best low-speed feel because it doesn't seem to make any difference in handling or traction below racing speeds. Docc may have the most data on mid- to high-speed curvy roads.

Not sure what tires the Sport 1100-i came with. The original V11 Sport was delivered with Pirelli Dragon Corsa sport tires and spec'd at pretty low pressures (33/37, IIRC).  They wore really quickly and (IMO) contributed to the high speed weave exhibited by some of the early V11 Sports.

With sport touring tires, I gradually settled on 35/40 as a compromise between road holding, longevity, and tire wear characteristics.  These pressures also pass the "10% rule" on my Sport with its load-out, local road conditions/temperatures, and my weight in gear. I recently mounted my 58th tire on this V11 Sport.

Certainly there is no more applicable topic to say "YMMV!"

To expand on this, as the tires (and the air inside them) heats up the pressure will increase.

Tires are supposed to heat up a given amount in use. That increase in temp will create around a 10% increase in air pressure. That increase in pressure can be higher, up to 15% higher, if the starting temp was lower (like when it is cold outside). But for typical motorcycle use you should expect to see a 10% increase in tire pressure if the starting temps are typical motorcycle temps and the tires are pushed hard enough to get them up to temp.

It is science.
