I'm considering installing a set of heated grips for the upcoming fall/winter riding season. The HOTGRIPS on ScooterWest are $80 and the same product as the Koso heated grips on Amazon for $55. At least I think they are!

Before I order, can somebody confirm that the diameter I need is 7/8" for one grip and 1" for the other?
I couldn't find a verified source of handlebar diameters - also wanted to share the good price in case any of you were thinking of doing the same on your Vespas.
