So some of us might run slightly lower when solo without losing sleep
This means I can go for a 2 week trip having set the pressures and not lose any sleep at all during the 2 weeks as the dash tells me I haven’t had a blow out.
Measured the tyre pressures when I got home and they’d drop 1 psi in 2,200 miles over assorted roads.
this is what the manual says - if the OP does not have one then you can get a free download in PDF format form the BMW website
if the bike has electronic suspension then adjust the preload by pressing the button on the left bar - it is this suspension adjustment that compensates for the added load
if the bike has manual suspension the RTFM for how to adjust
