My neighbor had a DL1000 and a Duc ST2 that he would let me borrow whenever.
it was amazing and most of the time he would ride with me giving me pointers.
However with the bikes not being mine I did not push the bikes at all... I had a good ride but any ride is a good ride.
Fast forward three years and I now have my own bike with 26 thousand + miles on it and we still go ride. Having a 650 when used to riding those other bikes there were some differences but I love my bike too much to care.
