Thats what I've read & heard. Hopefully I won't have trouble with them, but if so... oh well. They look great, and seem to function well in the little ride time I've got in. What really sucks is the HD versions are serrated where they mount to the "Harley only" type male mount. Why on earth they didn't do that for us or the metric crowd I'll never know..

Take care,
Jim

Edit: Well, I now see they do make splined adapters for a lot of metrics, but not Triumph. I'm going to give Kuryakyn an email to see if they might offer some soon, as this would alleviate the "rotating at will" issue. I've got a set of HD stirrups I could use if they'll make me the adapters!
