I have just finished doing some testing of my Infinity Subtanks on my new 640 adventure. My company makes these and this is kind of a plug but this is a different application for these things and I wanted to show it off. Because of the tons of crap under the fairing the best place to mount them was on the fairing/headlight frame. I am trying a new setup with ball valves instead of the adjustable control valves I normally use. This is so I can switch the system off for road riding and on for trail riding with the flip of a switch. I am running a 100mm oil height with this set up and it is helping control fork dive while road riding with the valves in the fully off postion. Turning the ball valves to the fully on position is really unrestrictive and has the feel of dropping the oil height down to a much lower level. So on the trail that make the forks more sensitive and has eliminated a lot of deflection in the rocks. The ball valves are not ideal for Subtanks. But they are really easy to use for this application so I am considering offering it as an option for a dual sport setup.
