If I didn't have a TPMS on the bike I would use it, but as I said before, It will mess up the sending unit. Ride on also balances the tires as you ride. I had zero weights on the front wheel of my concours when that stuff was in it.
Yeah, I can't see how this would EVER be safe for tire pressure sending units, like on the Concours. So even talking about if for the Concours, seems silly. Even if we were *SURE* it didn't damage the units, there is no question in my mind that it would void the TPS warranty.
But aside from that, if it remains "flowable", to "dynamically balance" the tire, then it seems to me that after a week or less of the bike not moving, it would flow to the bottom of the tire, making the tire severely out of balance, until it had a chance to "flow" back around and become evenly distributed. No?
