Whenever I've been off the bikes for longer than a few weeks, I find my cornering reactions are more like car driving ones. Several times I've found myself going into a bend and not leaning enough, a millisecond of corrective action has me going around the bend like it's on rails.Police RTA investigators have told me that in most cases of a single-vehicle m/c accident, where the rider has failed to take a bend, the bike could in fact have made the bend if the rider had reacted by correcting his/her line but they have given up by then.
This is compounded by not riding the same bike all the time, or simply just having new tyres on, which are all differences to accomodate to and learn.
