This is an OEM bar riser, 860201944 designed to fit the straight 7/8 inch, non tapered handlebar. Allows use of the factory mountain hoop handle. The shortest one available at 95mm, about 3 1/2 inches. I recommend this to be used with my zero rise bar, but will also work with the stock 7/8 handlebar. Will fit all gen 4 sleds.
