Conclusion:
When we ran the bike with each fuel at cruising speeds there was a noticeable "smoothness" factor that the cheaper gas suffered from. The dyno gave us the cold, hard numbers, but when fuel mapping and emissions are factored along with actual riding there's an important impression also-one that would prompt us to reach for the best gas possible each time.
The difference of one horsepower is pretty insignificant on the dyno, but over time your engine could perhaps show more wear and tear from running cheap fuel and suffer detonation issues because the lesser octane will potentially run hotter than the cleaner high-octane option.
The next time you roll up to the pump you'll know which pump to reach for...hopefully. With the way gas prices are going we're going to be at four bucks per gallon for the good stuff, and if saving three or so dollars per fill-up means that much to you then the cheap stuff will do, but you'll possibly notice a difference and perhaps cause internal issues down the line.
