Correct Tire Pressure ?

BMW says: Front: 2.5 bars & Rear: 2.9 bars
That is:
Front: 36 psi
Rear: 42 psi
Regardless of whether you are riding solo, two-up, or two-up with luggage.
I know it sounds too tight, but I wore out my first set of BT-021 tires at those pressures and never had any slip or traction problems.

TeddRi, Don't you have an owners manual ???
You can download one online.http://www.bmw-motorrad.com/com/en/.../services/manuals/manuals_main.html&notrack=1

Tire construction and rubber compounds are always being tested and evaluated. The grip, wet & dry, of tires on the newer BMWs has improved to the point that they are safe on the street at these pressures, and give longer tread life as well.
36F/42R or 2.5barF/2.9barR for your camhead.IMHO
