I was doing a little research here on new bars and was surprised to see people saying that you either need to cut off your hand grips or work them off with a screw driver and lube.. The fastest and easiest way is compressed air- if you have access- no matter how much glue was used you can pop off both sides in a minute- and this also aids greatly in putting the throttle side back on.

 

Yes, we have a couple threads with the info about using air, some even have pics showing this method.

I personally had ZERO problems getting mine off, they just rolled off like a sock on your foot. Required no tools and took about 15sec per side
