A small piece of plastic that can make riding much more enjoyable.  Have you ever been riding along and had your right hand cramp up from squeezing the throttle?  If you have this is the gizmo for you: the Crampbuster.  I stumbled on the Crampbuster while I was browsing an accessory rack at Life Cycle in Kalamazoo, MI.  It interested me enough that I spent eleven dollars and installed the Crampbuster on my bike while still in the parking lot.  Installation was extremely simple you just bend it open and slip it on the end of your handlebars.  Once on it has a ratcheting type grip on your throttle only moving round opposite the throttle for adjustment.  Once riding I found that I needed to rotate it way out of the way for city driving, but when on the highway it preformed exactly as advertised.  The cramp buster provides a very nice ledge to rest my hand on and uses the weight of my hand to keep tension on the throttle.

My suggestion to anyone who is interested in trying this device is be careful.  When I first installed it I had it at an angle that made city stop and go driving very difficult.  It took a few minutes but I soon learned to adjust it while driving.  I suggest trying it out for the first time on some side roads where you can get a feel for its position without hindering traffic.
