Interested in knowing what tyre pressures you guys use for normal road use with:
standard size wheels and tyres
one up only and no luggage
normal tarmac roads (with the customary potholes

29/32 psi on my Z with stock wheels and tyre sizes (Metzler Enduro 3 Sahara).

2.5 front, 3.0 rear

are these higher than in your handbook? mine says 29psi/ 2 bar

why do you guys run the rear higher? specially 3 bar = 42 psi!

Handbook pressures for the Z are 30 psi front and 33 psi rear, so mine are actually 1 psi less than recommended for solo road use. Not sure about Dual's 2.5/3 bar (35/42 psi) - that does seem a tad on the high side! However, each to the own - we're all different.

You must have birds nesting in your airbox if it only makes 37 bhp!

A few psi here and there may not make a massive difference to handling, but sure as hell can have a BIG impact on tyre wear and particularly how quickly the rear squares off.

interesting the R is 29/29 I guess the Z is heavier and different weight balance.

My curiosity is the reason for using a different pressures to the handbook (within a certain parameters: normal road use/ standard tyres/ no extra weight) not extreme use.

I found that with my recent tyre change to a different manufacturer, I now run the rear at 26~27 to calm the bumpy rear end.

BTW 2psi difference from standard is noticeable in terms of handling and bump absorption (perhaps even 1 depending on how much natural padding you carry)

Indeed. Every different brand of tyre I've used on the Z I've run at slightly different pressures to get the best compromise of grip, wear and comfort.
