The risers fit perfectly. I followed the directions by applying heat to the studs and I had absolutely no problems installing them. The whole process took about 25 minutes. I personally put the handlebars forward over the headlight, so that the studs stood straight up. I folded up a towel to put between the headlight and the handlebars. I went for a ride after installing them. I was very satisfied with the feel of the risers in the new seating position created. I sit much more upright. Definitely a 5 star product!
