I am the original owner of a 1982 Honda XR200R. I have found the original IRC Vulcanduro tires to be OK but that the rear grip was a bit too much such that to get good balance and crossups I really had to get my butt up towards the tank. Those tires are long gone and I have ordered replacements. Coming are a Dunlop D803 for the rear and an Pirelli Scorpion XCMS 80/100 for the front. I am not sure how the balance is going to work out. I figure to run the very tall D803 at low pressure and to obtain a suspension effect from it to help with the XR200R suspension. I hope that the Pirelli front tire will balance its grip well. Any comments on this or similar combinations?
