You may get a short ban or 6 points. You can reduce the chance of a ban by indicating that you wouldn't be too inconvenienced by it e.g. say you can easily get the bus to work.

I got 6 points and for also doing 95 in a 60 on the A65 to Kirkby Lonsdale on my CBR600 - same scenario - nice long straight, click down into third, pass a load of cars and then a BMW traffic car appears a few minutes later.....

Had to go to court - pleading guilty by post wasn't enough.
