be sure to buy a surplus of reg/recs with it , they are a lovely bike to ride but i think the build quality is proper ***** , ( worse then the boxheads)
not really sure an ohlins shed R is worth 10K either but that just my opinion.
They are almost certainly quicker through the corners , however not very difficult to pass on the straights.
I could never get used to the constant up and down the box either , I must be getting old
good luck with the test ride Phil , hope you enjoy it , are you just fed up of the beemer????
