One thing I got very used to up here was bumpy curves. In general the roads here are very twisty-obviously a good thing-but the harsh winters and freeze thaw cycles tend not to be kind to the road surfaces. Personally, if possible, I will always avoid the rough spots at the expense of taking an imperfect line through the turn. However if you don’t have time to alter your line or if the entire width of the lane is a mess just roll with it. Try to scrub off a little extra speed before you hit the rough spot and as Munch said, relax, and once you’re on it roll on the throttle a little just as you would on smooth pavement. If your speed is reasonable and you’re not dealing with serious gravel or an edge trap it shouldn’t do much but shake you up a bit.
