Honestly, this Kipass system thing scares the ever living crap outta me.
I've never really understood the fear of kipass myself. I have two active fobs, one stays at home & the other in a inside zippered pocket of my riding jacket. Rarely take it out, I use the stove knob key at every fill-up & to open side cases. This has worked for me for the past 14 years & 271,000 miles. They will be many I'm sure that will say the stove knob key will bend & are afraid to use
As for the tank bag thing, I don't think my bike would run without one, mines always mounted. Been using one since the 80's!
