I hate ordering stuff on line when I don't know exactly what I am getting, so I went to the Honda shop and had them order me a screen set for a 76 550 F and a rear tire. the tire ordered was a 110/100/ 18 when it came in it was a dirt bike tire.
since I want this bike to remain mostly stock, I settled for some vintage remakes sim to original equipment, I was looking for something a little more modern looking.
Good luck
Mark
