I've used less than the suggested amount, and still had very good results. One thing to note, if you leave your bike parked for a few weeks, it will settle on the bottom and shake a bit on the next ride, until it warms up and sorts itself out. I love the balancing part, but mainly got it for the puncture protection. I don't like sitting on the side of the road waiting for a trailer. Even though I use Ride-ON, I still carry plugs and a small compressor.
