He's got an SV1000. Motosliders don't make them for the 1k's (since they're no longer being produced). IIRC Nucular (who did the prototype design for Motosliders) is working on a set for 1k's, but doubt he'll do more than a few runs.
I have sent out 3 sets for the SV1000 and am just waiting on feedback from the people that got them. If that all goes well, I will have another dozen sets ready for sale. It will probably be once I get back from the rally.
Here is a link to the post I made of the prototype. The actual version has rounded pucks and zinc coated bolts. I will try to post up a picture later.
