    From the timeline above:

    “1995 – Jim McClure’s first person to go 200 mph on “Da Judge” in the quarter-mile on a Rivera sponsered HD drag bike.”

    From the S&S Cycle Website:

    “Andy Gotsis set a record of 7.016 second ET at 200.31 mph on May 6, 1995 aboard this supercharged, fuel injected, nitro burning drag bike, campaigned by the S&S sponsored Hubba Hubba race team under the leadership of George Smith Jr. This was the first v-twin to exceed 200 mph in the quarter mile.”

    I can’t seem to find the date of McClures 200 mph run.

    Who was the first to 200 mph in the quarter mile, Gotsis or McClure?

    I am pretty sure it was Jim McClure, but I was wrong once!
