I installed the trhottle boss with my grips and love it. Most of my riding is in groups and the ruise control just doesn't work unless you are the lead bike so the thottle boss gets used almost 90% of the time. No more cramps in the hand after a long ride, just rest my wrist on the boss and adjust the pressure to maintain proper speed. For such a small cost, the thottle boss is well worth it. :lol:
Often times when you ride with others you are not able to use the cruise control. I doesn't take long for you hands to cramp. The trottle boss is great for using you palm to control the trottle and give you fingers a break.
Do you absolutely need the Throttle Boss, probably not, but it's sure great to have and where can you find an accessory addition that looks so good and that you'll come to enjoy for your Wing for only $16.95?
I installed them on both sides of mine. If you are doing it so both grips look the same, it doesn't really work, because to have the one on the throttle side in the correct position for use, it can't sit in the same as the non throttle side, because the throttle one must be positioned so it is at the right angle for use whe the throttle is twisted.
I use my thottle one quite a bit, because I am a control freak and rarely use the cruise control. So being able to relax my grip is very important. So the Throttle Boss Works great for me!
