Skidmarx won't ship to the US. They referred me to http://streetfightersbydesign.com
their US distributor. I emailed the distributor about pricing and availability but never got a response. However, I later stumbled upon the hugger (superduke) for sale by them on Amazon.
Another option: http://www.simpson-detour.co.uk/Hugg...2-cfc411906c55
And they'll ship to the US. Some find this better looking but installation is trickier than Skidmarx.
I ended up making a fender extender out of ABS plastic for $2. http://www.ktmsmt.com/viewtopic.php?f=7&t=3597
