I had to replace the clamp on my Vespa, the OEM version of the clamp was $25, Shindy's was $7, I said I would take a chance. It is about 4mm less wider than the OEM clamp, but it is doing the job. I have had the clamp on for about 3 weeks and I have ridden about 80 miles on with it, thus far no issues to report. Will find out if it rusts once the salt on the road comes on. Overall a good quality product for a fair price.
