Hi Still, there are quite a few people on the forum who will be able to give advice on this subject. But what I know about it it's at very high speed, was attributed to the way the UK Police had set the bike up.
Normally it won't effect you as if it was to happen (which is extreamly unlikely) you'd have to be well over the speed limit. You have more of a chance of a roo jumping out in front of you.
I've had mine up to $180 and she was as solid as a rock, very balanced, very stable and just purred along.
As I said, there are quite a few who have more knowledge about it than me, my advise to you would be don't stress about it, keep searching for your red beauty.
