Throttle lock on my bike is a spring loaded set screw. Get up to speed, give the screw a nudge tighter, it friction locks the throttle. I don't use it, after 15 years the throttle return spring on my bike has gotten weak, tends to stay open on its own.
I have a rubber hand rest. While they work great, I can't take my hand off the bars and place it on my leg to relax it or shake out the numbness.
Then you need a better fitting handlebar. If your arm/hand is going numb, you've got the wrong set up.
Lisa's 800 Intruder now runs 10" rise mini-apes. The stock bar was too low (and not adjustable, locked in place via riser tangs and bar slots). My Savage currently has 15" rise bars, but I need to shove them forward a bit and repin them in place (the stock risers don't work well with high bars).
Put a chunk of 2x4 under your kick stand. Sit in your normal riding position, let you arms and hands fall to a comfortable location. That's where your grips NEED to be. For most riders, that means stock pullback or drag bars hit the recycle pile in favor of a higher, wider bar.
I ride with high bars because I like them. Am planning a 3" or so height drop soon, and my tracker bend equipped CL Honda is getting a higher set (more like KZ440 bend).
