How-To: Change Motorcycle Grips the Easy Way
By far the easiest way to remove grips is to use an air compressor and blow gun. All you have to do is lift the grip up, and shoot in 100psi. The air pressure causes the grip to slightly inflate/enlarge, allowing you to easily slide it off and on.
Looking to replace worn or torn grips? I like the Scott half waffle available at Amazon.
