Never ridden there....here is something from the STT site:
A trip around the 1.9 mile track on the Aprilia Mille, goes something like this. The front straight is 5th gear, appox 130-150 MPH , This is a nice long straightaway (you want to stay to the right edge of the track as you get mid straightaway) which ends by running you over a blind hill (again staying to the right) into a left hand 3rd gear corner (This corner is somewhat decieving in how fast you can take it, if you are to the right this is a fast corner and also bumpy). You then begin a sweeping right hander into turn two (2) (never really got this corner right all day) you can lose alot of time here and when you exit the corner (assuming you've got the corner right) you'll get a fast drive down a short straightaway anout 90-100 MPH ( somewhat up hill) to turn three, decieving, this corner again is a sweeping corner that looks tighter than it is. If you take it right you get pushed out to the edge of the track and it's a little bumpy on the exit. It then sweep to the left almost full throttle in 3rd gear, about 100-120 MPH (a small breath at turn four) on the throttle at mid corner (you are running somewhat downhill) into turn five (5) and as roll through turn 6 you head up hill (theres a big dip on exit) and as you accelerate hard uphill (very bumpy) into turn Seven (7). This is another odd corner, you pretty much want to turn this into a long sweeper, probaly a 100-120 MPH, from Turn seven (7) through Turn's eight (8) RIGHT and nine (9) LEFT, again loads of bumpy sections, and heading downhill somewhat in to turn 10, which looks tight, but can be taken as a sweeper, your pushed out to the edge again if you have the speed. You stay to the left on this straightaway about 100-120 MPH, very bumpy into turn Eleven (11), big dip into this corner, if you can stay left it is a smaller dip which throws you onto the front straightaway. Head down, easing over to the right as you approach the blind hill for turn one.
