It gets worse if you are going fast too as you really 'feel' the flex in the head stock but what can you expect from a bike whose front forks are only just bigger in diameter than drinking straws from McDonalds ? The front end gets all out of shape from the rest of the bike but it generally behaves. Nothing Mr Spondon, Mr Metmachex and a fat wedge of £££ wouldn't cure.
The RD500 is a pure pig to tune. Weird engine config but it is a true V4 even if they blow up for fun and the bottom end goes kaboom at exactly 20K miles

4 cylinder 2 strokes are motorcycle sex in motion
