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.
