But why is what I want to know.
All 3 gens have top plates with handlebars that slide in.
Are the gen3 handlebars a different diameter at their mounting point than the gen1 and 2?
It would seem foolish if they were, as most bars are the same diameter throughout, standard 7/8" for the grips.
Helibars will also tell you that gen1 Helibars dont fit gen2, and vice versa...but they both do, and are identical other than switch mount locator holes in slightly different locations, as said above.
I would not be suprised if the only difference in gen3 handlebars vs gen 1 and 2 is once again only switch locator hole location, and that gen1 or 2 Helibars will actually fit the gen3.
Hopefully someone with a gen3 and a gen1 or gen2 can check their handlebars for differences.
