ran a Buell for 50K and never serviced it just to see the wear and they also ran a 4pot Jap equivlent and compared.
the out come was the Buell was carrying its miles very very well as even in Buells tune it was under stressed and the wear at 50K was still well within tolerances and the honing on the barrels could still be seen !!!!!! the 4pot needed quite a few of its bearings replacing and some parts were out side tolerances but again nothing major and easy fixes
Don't see why my 09 won't outlast me and my son's plannin on it!
