The Viper ER with electric start and reverse gains 29 pounds and suffers a tad in performance. Truth is that on the first day of our test ride, before the Vipers arrived, our crew made certain that the Indy 700 VES was chosen first. Like we said, based on our test ride, we were a bit surprised at our own radar results. The performance differences are close enough to make us believe that under different snow conditions and at a different location that the results could be turned around. In fact, in a matter of 24 hours on the same lake, the Indy gained four percent in performance from the previous day's radar runs against four 800 twins.
Conditions make a difference.
Here is what we found at Area 330. Make of it what you will.
