I took a ride yesterday .I normally cruise at about 105/110KPH and get 18.5 to 19.5 KPL.
Yesterday I had a road with very light traffic and I cruised at 120KPH,touching 130kph at times, for an extended period.The America loved it!It ran great.
The only downside is it only got 16.5 KPL,so it's defintely thirstier but I don't imagine I'll ever need "more" bike.
She'll do me.

Having said that, I suppose a T-Bird in the Garage would be nice too

[but I can't see one in my near future]
