Would leave a Black Shadow puffing in the wind to keep up, but the H1 500 - 3 has no class or predigree just acceleration. 0-60 in 3.2 seconds and standing quarter in 11.2 seconds. Mine was production race tuned, and was a lot quicker. Wheelie in 1st and 2nd, shift the weight forward, and pop the clutch and smoke the back wheel at 70mph. I wish I still had it even though it handled like it was hinged in the middle! I used to have to carry a pocket of platinum tipped spark plugs as they fouled often in city traffic. My reg number was WTO 127J. I keep toying with writing to the British DVLA and seeing it it is still in circulation.
Hope you are able to ride real soon. The weather is just great for it. The Vincent is a wonderful piece of engineering, and you certainly won't ever lose money on it. The factory was just up the road and I also had friends that worked at BSA and Triumph.
Meant to say, my friend had the Guzzi 850 with automatic clutch and running boards. Nice bike.
