OK, so this can be the resurrection of the throttle lock threads (lost in the forum crash).

I, for one, have CTS (carpal tunnel syndrome) from way too many years of keyboarding.  What this means is that after 15 or 20 min of trying to hold the throttle, I my fingers will start to go numb, and/or I can get pain in my wrist.  This is actually not an uncommon problem with motorcycle riders.

A throttle-lock is a device that will hold the throttle open so you can momentarily remove your right hand from the handlebar and "shake" the feeling back into the hand.  Or just reduce the gripping force which also helps.  It can also help with hand cramps even for people without CTS problems.

There are many types of throttle locks.  Most of them fall into three categories- those that clamp on the bar end, like the Throttlemeister, those that grab the handle on the outside, like the Go Cruise, and those that grab the throttle tube near the inside, like the Vista Cruise or NEP Cruise.  The bar-end ones are invisible and long-lasting.  But they are harder to use and can be very expensive.  People claim the Go Cruise is cheap and effective- but it does have issues with certain covers, and robs some hand space.

I have my eyes on the Vista Cruise.  There are two types- the universal, which is bulky and ugly, and the non-universal, which is sleek and small.  The Vista is relatively inexpensive, simple to operate, and the non-universal doesn't rob the operator of control space.

I don't have a Vista on the C14 yet (did on my old ZRX a long time ago).  From previous forum research  it seems the correct Vista model number for the Concours is the Yamaha version, model MCVICY-P.  But I am not sure it will work properly with the 2011(/2010) which have heated grips, so there is a larger lip and a wire where it would mount.  Has anyone installed a MCVICY-P on a 2010/2011?  Was it successful?  Please share installation and use experiences and pictures.

Of course, postings about other throttle locks are welcome.

I have the Throttlemeister and it works great.

But.....

I later bought one of these for my other bike and it works great too. Easy to use, easy to remove and simple design. Best yet it is less than $20.

+1 Throttlemeister, took some time to learn to use it, now it's great.

I use the GoCruise also.  It's about as simple as you can get.  Works great.  It just irritates me to pay $20 for a 50 cent piece of plastic.

I just ordered one today, and I have no problem paying $20 for it. The Cat oring works just fine, but this looks just like the ticket for me. The Crampbuster's are also cheap plastic, but they too really help on the slab. I may very well invest in a Throttlemeister eventually, but going cheap for now will suffice.

I've never used the Crampbuster myself but I see them on alot of bikes. Are they in the way for just normal riding? Do they really help on long flats?
 
Thanks.

I've used both the crampbuster and throttlerocker brands. They allow you to loosen up your grip while maintaining throttle pressure. They do work well. But they do not allow you to totally remove your hand from the throttle to shake it out a little like a throttle lock. These are good, but not as much by themselves.
 If you use decide to use one. I recommend the throttle rocker over the crampbuster. Although the crampbuster gripping the throttle grip is better. The Carampbuster is a straight piece of plastic that's not ergonomically shaped to fit your palm. I use to tend to give me a sore or blistered palm after use. Where as the throttle rocker is shaped with your palm and thumb in mind. So it tends to fit your hand better and not make your palm sore. So I recommend the throttle rocker over the cramp buster.
 But like I said, they are good, but use them in conjunction with a throttle lock or cruise control for much more versatility in riding comfort. Of course this is just my opinion!

It looks like the Crampbuster's do make both a "palm shaped" one and a longer skinnier straight-type one as you mentioned.

I have something similar in concept I used on my ZRX- it is a rubber, "strap-on" type of thing.  I don't use it though, because it really didn't help much.  In my case, I have to remove my hand totally and rotate my hand around a few times to get feeling back.  I also felt less in control with this type of thing.

I attached a picture of it if you are curious.
EDIT:  Oh, it has a name on it- it is called "Throttle Boss"

LOL!  Didn't even cross my mind until after you forced me to re-read what I wrote.
