What is Speed Lockout on a SUNTOUR fork? Looking at entry level SR SunTour suspension forks, there are the options of 


"MLO" - mechanical lockout
"HLO" - hydraulic lockout
"RL" - remote lockout


Now, mechanical and hydraulic lockout is clear. Remote lockout - not so much - it says that it is engaged from the handlebars, not from the fork itself.

My forks says XCR 011 Series mg. On the side of the knob is written "Speed lockout". I am able to lock the fork while compressed, but if I do it uncompressed, there is some small damping still, which is very nice. 

How do I know what is this "Speed lockout" thing, without disassembling the fork.

Note that I have been unable to identify the exact model of the fork.
Remote lockout means that the fork has a "remote" lever that is installed in the handlebar. 

My fork is a XCR RL from 2011 as well and pressing the blue lever locks the fork, pressing the black lever on top of the blue unlocks it. This is a XCR from 2011 as well.

You can see the remote in the following picture:



If you have a knob with speed lockout you should have a fork similar to SF11 XCR LO 26". If your fork has rebound adjustment then it's a XCR LOD. You'll have to look that up in Suntour's site since I can't post more than one link.
