oh! I forgot.
I rode the speedy from up state new york to the boston area last year....i was solo. I felt that with a 1/2 helmet and no windsheild that 70-75 was my sweet spot. BUT quick role ons up to 90-95 was great for this displacement. Again, it isn't a liter inline 4 by any means but MUCH better then a 900 (or much bigger) vtwin.
