Motorcycle Consumer News tested a Speedy in April of 2003 and it ran 14.47 @ 90.1 mph - and now a few comparison scores from MCN:

Suzuki's Boulevard M50 ran the quarter in 13.99, the 1200 sportster clocked 12.99 @ 100.11, and the 883 did it in 14.98 @ 88.93; the only other Harley the Speedy bested was the FLHTCUI that ran the quarter in 14.75; the Road King sauntered through the lights in 13.94, the Wide Glide at 13.21 and the Super Glide made it in 13.47. The Honda Sabre (1100 cc) ran it in 14.26; the VTX 1300 turned in a 13.50.

I don't have a good way to document this, but my Jet Black America ran the quarter so fast I didn't have time to check the numbers... So clearly, MCN's wrong, right?
