Hi all BT1100 experts I've just bought a 4yr old Bulldog, all sweet, except for the handling - damn thing is so twitchy, and in the wet the rear constantly spins up (only 65hp for *** sake!). It's on new Metzeler MEZ4 ZR 120/70f - 170/60r - any info on these or any other replacement tyres (and handling tweaks)? cheers Marek
