Good product, Great customer service!.
Ordered these and many other parts for my 690. Initially was sent the wrong set of sliders (had the right part number so they simply got mislabelled). I emailed about it and Ron from KTMtwins sorted it out for me ASAP. I will order from here again! Great service!
About the sliders, I haven't dropped the bike with them on, but they look like they will stand up to significant abuse.
