If you want to learn to get your knee down properly then come to Basingstoke, a)cos we're second only to Milton keynes for number of roundabouts,and b) we have, what i call, the AA loop (cos its right next the AA building HQ). its where one dual carriage way joins another at a 90 degree angle, but as the sensible road designers cant have people doing a tight turn at 70(ish) mph, they put in a slip road that to me resembles a plane taking a wide turn.
coming into town you take a longish left, and then a looooooooooooooong right to basicaly come back on yourself, coming out of town its just a 270 degree left. they got resufaced not that long ago so are nice and smooth, and so easy to get your knee down on, plently of time to just lean it, lean a little more, lil more, just, a, little, more ssssccccccrrrrrcccchhhhhh!
Its where i learned on a streetfighted Bandit 400, so if i can do it on that you can do it on most stuff!
