Doesn't take that much horsepower to get to 130 mph. Most 70's era 1000s would do it... about 80 rwhp.212 km/hr?!!
That is 131 mph- pretty damn impressive for 1920.
Thanks for sharing Mscuddy. How many square feet of boards was that track? The track must have made an odd noise when the bikes roared past. Like a bowling alley from hell?
Now getting up to 150. That's a lot harder. More like 120 HP. I could do the formulas but I'd rather let that keyboard in Seattle explode into 1000 pieces.
