I ran it 150klm in total yesterday from scratch or pick up and that's a pretty good run by my standards with a new bike. I did probably 40klm of dirt road too. that would be the longest dirt run ive ever had on a bike. also ran along at 50 mph on the sealed stuff so I would say it would cruise at 60 mph once run in.
this may surprise but I don't think power wise I am that far behind a standard 500 uce. i'd say a cross between a 350 and 500.
