As mentioned b4 carry on past the 1st ashford turning (becomes the a252) to cholock good rd surface some nice twist normally a quite rd with just the right amount of straights to pass anything u may meet !! At cholock roundabout turn left towards Ashford (A251) long straights with some tricky down hill bends !!
I normally set of from Ashford go up the a251,a252 & then turn right onto a28 when Im trying to dial in suspension as it has a little bit of everything (a28 being the rough)
I agree heading towards chillock then turning left to ashford would be allot more fun.its a good road just to take it slow and enjoy the ride aswell as open it up.
You might find it slightly more interesting to carry on up towards Challock, there are some superb quiet sections between the Ashford turn and there.
Quite a nice route from the wonderful city of Canterbury through to Ashford where you can get the train down to France, a particularly interesting bit is between Thanington and Chilham. Quite good.
