I have a 2011 Road King Classic and looking for suggestions on best Tyre Pressure. 110kg solo

Check ya manual for tyre pressures. I have same bike and run it at book levels no prob. I am around the 110kg as well. A worthwile purchase though for these bikes is the pump unit for the suspention. I find this to be more critical to the bikes handling than tyre pressure being a KPI or 2 up or down! oh and compliments on buying the RKC. If god rode a motorcycle it would be a 2011 RKC.

Thanks mate yea I have got a H/D pump as I thought s/aborber pressure would be critical to handling. Manual says 36psi front and 40 psi rear?

Yea, I go along with all of this... Just remember the difference hot and cold tyre pressures can be as much a few psi, less in winter...  I would say that 40 psi cold at home, 40/36-38 is about right, but that is cold at home where I have a compressor for the tyres...   If you ride very far to a Servo, you need to up that in my opinion, at least a couple psi in winter and maybe as much as 3-4 in hot summer..  Failing that and you could be a bit low on air and wallow a bit when back on cold tyres...

Oh, and be careful, DO NOT attempt to use a compressor on the air suspension or you will ruin it.  The little hand pump is the go as the volume is so small.

Cheers, Cowboy, horses and Harleys...

I'm running a metzler marathon on the front at 40 psi and a dunlop e3 elite on the rear at 42 psi cold

I run Metzler ME 880's on both ends of my 98 RKC and with no pillion 36 both ends, 40 in rear with the bitch seat occupied.
