ZRX1100 Tyre Pressures

I've been riding my bike on the tyre pressures recommended by the manufacturer since i got it but it has always felt slightly heavy at the front end. At anything over 20mph the weight was hardly noticeable but at low speeds it was too heavy! I decided to do a bit of research and found that the recommended tyre pressures don't go down too well with any ZRX owners! The best pressures to run are 36psi in the front and 42psi in the rear. It now feels like a different bike!
