These handlebar clamp risers are a disaster in my opinion .i use my motorcycle for long road trips, and I bought these thinking they`d be a great comfort upgrade. Unfortunately they have failed on me multiple times during rides, causing me to pull over and fix the issue. The one good thing I can say is that the material does seem durable, but that's not enough to make up for the overall lack of reliability. Overall, I do not recommend this product to anyone in the automotive industry..See full review
