Tested the Pro v/s Standard Muzzy in real life run. Four Stoke Tech had the same results. The standard on a straight line drag the bike would be slightly quicker than the pros until the very top end 70mph plus. Standard Muzzy shinned more going uphill. The pros will pull more HP on the Dyno but not in the real world unless you are reving really HIGH more than 9500 RPM's. These test were on 840's we have two to test and play on since we actually own them. The pro's do run a little cooler and have a diffrent sound, a little quieter .. Standards have more of a small block chevy sound and the pro's a little more racey sound.
