Street LevelAfter the drag racing was completed, for one final comparison we took the two bikes out on the back roads of Cook County, Georgia, for a little spin. These were, after all, streetbikes, so we were curious to see how the turbo and nitrous compared on the open road, as typical riders would use them. In other words, let the roll-ons begin. We started with both bikes cruising side by side in top gear at 45 mph. On signal, both riders nailed the throttle (plus nitrous button on the Vulcan). In top gear the torquier Vulcan walked all over the V-Rod, working up a yawning, eight or 10 bike-length lead that would hold all the way up to around 115 mph, at which time the V-Rod's turbo would have had time to spool up and it would blow by the Vulcan with a 10-15 mph advantage. Fourth-gear roll-ons yielded a similar result except that the initial jump by the Vulcan was smaller due to the fact that the V-Rod was higher in the rev range for this test and closer to its power peak. Repeating this test in third gear (with the V-Rod this is the meat of its high-revving powerband), the turbo Harley would easily leave the lumbering Vulcan in its dust.
