Fantastic MOD!
I usually drive vintage bikes, lapping nurbugring in 7.51 with honda rc30 is very realistic,i'm not so far from the official laptime for this bike that is 7:49.71 on 23 may 1993 with Helmut Dähne as rider.
Original physic is much permissive, with this mod is another game but i find difficult to drive bikes with more then 150 horsepower using keyboard.
