Anyone here ever have the privaledge to ride all of these (vintage only) to compare power (and more) ? I'm curious how much more 'engine' the Bonneville 750 or Norton 850 might have. Especially since the Norton 750 and 850 have a undersquare (meaning smaller bore than stroke) stroke of 89mm. The Bonn 750 also has a stroker motor. The XS is slightly oversquare at 75x74. My lust these days seems to be for a Norton 850 Commando Sure wish I knew someone in TN that had one - that I could take for a low rpm spin I'm really only interested in torque, not speed or rpm's. If I really wanted to go fast, I'd buy an R1.
