A little but you do get used to it. You will find it much much tighter in the bends.
Obviously as mine had lead weight over thr front wheels it had a tendancy to plough straight on in the corners if entered too quickly.
The ATB transformed it, as long as your on the power it will get round nearly any corner giving maximum grip, if your off the power then it does get a little loose.
You wont take long to adjust to it and you will soon find nicer lines through corners
