Everything is relative. Any reasonable displacement, modern motorcycle is "fast", when compared to most cars on the road. And for Jim, what he has might be plenty fast or "fast enough."
Now, compared to a C14, a Roadmaster is not fast....
Stock C14, 0-60 2.9 seconds, 1/4 mile 10.56 seconds (no flash or anything else... stock)
Stock Indian Roadmaster, 0-60 4.7 seconds, 1/4 mile 13.6 seconds
There is only so much you can do with an unfared, nearly 930+ pound bike, having only 2 air-cooled cylinders (!!), even despite the huge 1.8 liter displacement.
And how about my reasonably fast car?
Stock G37S, 0-60 5.0 seconds, 1/4 mile 13.5 seconds
