For solo Rider + Luggage it says 2.1 bar F 2.8bar R without checking that's how l got to 32F 34 R .....(QUOTE)
I'm wondering if the front feels skittish due to the ride height, not the tyre pressure.
By the way, you need to look at your figures again - 2.8 bar equates to 40.611 psi (at sea level just to be pedantic).
