Been meaning to pass on this info especially for those who have original foam grips that are showing wear. About ten years ago, I purchased some foam sleeves that went over my original grips. While I liked their comfort and feel, the quality of the foam was was not nearly as good as the original grips. However, the original grips on my 88VR were wearing badly so I decided to look for some new foam grip covers. I finally found a manufacturer that makes them - called "Grab On Quality Foam Grips" in WA. To my pleasant surprise, they make a size that is a perfect fit the 5in long x 1 1/2 in diameter original foam VR grips. They stay in place without need for any glue and are extremely comfortable and durable (so far). The manufactures says they are made from extra durable EPDM foam and claims to guarantee satisfaction. They are also an inexpensive fix at a price of about $10.
