And see if I`m happy, I understand I can monitor the pressure and the wear and tear to see if its okay.

Stop me if I`m wrong :)

34 psi in the front tire sounds way too high to me as I suspect that will make the front tire hard as a rock. My front tire is a 100/90 V 19 Pirelli Sport Demon, and I run 26 - 28 psi in it. It works great. Ed

Thank you, I have:
100/90-19 M/C 57H MT66 Pirelli
130/90-16 M/C 73H MT66 Pirelli

Front:
26 - 28 psi, okey.

Rear:
What shall I start with here then ? what do you have ?

When in doubt, check with the tire manufacturer.

Recommended pressure for the MT66 and Sport Demon tires is 2 bar (29 psi) front and 2.5 bar (36 psi) rear.

I have sent them a email, but no replay.
Wow the information I found on a forum is wrong then....

The pressure you list up I shall use, must I take off 2 psi compensate for warm/heated tires or can just fill 2 bar and 2.5 bar on cold tires?
Just for double checking....

Again thank you ! :)

Tire pressure recommendations for street bikes are for cold (ambient temperature) tires. There will be a slight increase as the tire temperature increases.

The information I posted was straight from the Pirelli website. No need to email for the answer.

What meant was I sent email to Pirelli one week ago, but have not got any replay, I trust your information !

Will test the tire today with correct pressure :)
