    OK, I may be sorry i asked, but kind of a noob question - just installed new handlebar rubber grips, and on the throttle twist, hard to tell, but there appeared to be some dried up grease within the twist mechanism. anyway, dead end on the search on the subject of lubrication. so the question, light lube with something like lithium, silicone, synthetic, ???, or bad idea all together. I solvent cleaned everything and it feels pretty good as is, but it's just metal to metal contact at this point. same lube question on the twist grip, rotating center shaft and the handlebar itself. TIA

    Whatever grease is to hand.

    My Triumph manual for the modern bonneville calls for just engine oil as the twist grip lube. I do use light grease on the commando however. Works well for me.

    I'll add, when using the grease on the commando twist grip, I've found the little throttle hold "clutch" screw doesn't seem able to hold the twist where I want it to...seems the slip back to open within a minute or so due to vibrations? So maybe htat needs to be grease free if you intend to use it.

    I use Mike's Bike Grease on light applications like this.

    Works well and is not as heavy as auto types.

    The only time I use grease in the twistgrip is if I’m wanting to keep water out (winter prep or going on a long run in the rains, neither of which I do much of these days).

    Too much grease can impede smooth action and / or return.

    Personally, I tend to assemble twistgrips dry, with a spray of WD40 dry film lubricant that I’ve become a fan of these days.

    Modern bikes = plastic throttle tubes. No lube needed, or light oil if you want.

    Cdo uses a metal throttle tube. Lubrication is needed on all metal to metal moving mechanisms. What KIND, could be debated. I’ve used moly grease (on hand for ball joints, TRE’s, and all sliding devices) for decades. Mainly because it stays the job longer, and I have lots of junk that needs attention . As mentioned, any grease will do. Not only the I.D. of the tube, but that tiny flange in the housing gets it too. If it wears away, (and they DO, with no lube) and your right hand suddenly slid off the bar with the grip & tube, inertia, and your body’s weight would HAUL YOU BACK, the bars go full left and you crash. HARD.

    My choice is Dri-Slide. A dry moly film in a fast evaporating solvent that doesn't dry sticky and attract dirt.
