Damping Handlebar Vibration
From Pvdwiki
BUZZZZZZ....
A vibrating handgrip will cause discomfort and the hand to fall asleep. Weight is usually the fix.
The aftermarket has a few examples of large bolt on weights for clip-ons to fight this. If you can find some of these, give them a try.
Stock Clip-on Modification
Stock handlebars will almost always have some sort of weight inside. This is to reduce the vibrations at the bar. A problem for the non-racing rider is that these weights are kept to a minimum to score points with magazine editors regarding overall bike weight. So our bikes are light, but they hurt to ride. Let's choose to add a little weight and make the bike far more comfortable to ride.
