These work better on older bikes since they are longer than grips on many newer bikes...I've used these for years, on several different bikes, because of their good grip, excellent vibration dampening and long wear.
My husband turned me on to the Oury grips. He has used them for years on his dirt bikes and bicycles. I have them on my KTM 200 EXC and have come to reailze just why he only uses Oury. They are grippy, soft, dampen vibrations, and the larger diameter is easier on the hands than gripping the smaller diameter grips all day.
I have been riding street and dirt for over 40 years. Have tried every style of grip there is-- including the new Gel grips. These are the only ones that keeps my hand from cramping . I have them on all 10 of my bikes. Scooter, Vintage, Dual sport, or Sport touring, they are the best.
