I mounted them on my own replacing the Metzlers with the Cobra Chrome tires on my R3T back in October. Have put about 4k miles on them since. It was my first time doing them myself and not bad at all. I just used all the tools and followed the process in this video from Motorcyclist Magazine:
Tools were less than $200 total and essentially paid for themselves in that one change due to local charges at the shops just for mounting (silly East Coast prices). Only thing to really keep in mind is having the bead wet with soapy water when working it over the rim. I used soapy water and not Windex. Was concerned the ammonia of the windex would dry the rubber. The shops use soapy water anyway.
Next year I plan on trying out Dark siding now that I feel like a pro at busting tires off the rim.
