I don't know if Mike can get away with that as easily as I get away with calling Tony my ex boyfriend"ex girlfriend"
I fitted Koso Apollo heated grips (from Revzilla). They work just fine (and a lot cheaper). For my Indian Chief I installed the factory heated grips, it wasn't cheap but they work well.
All the bikes I have owned have heated grips in some form. I must be a girl's blouse.
I would be surprised if the indian ones arent made by Koso, just rebranded, though the 3 vs 5 settings is different. Sure look like them.
