That is the best set up I have seen yet. The KTM version should fit anything at least 10 years back. You would have to have a full DC conversion at 100W or more to run both squadrons plus battery charging, etc. I have converted my old 520 to full DC with a trailtech stator and would love to install this. Looks like it would bolt right up. Looks very well-made at a reasonable price.
Your KTM version should work on Husabergs back to 2004 also. Same basic clamps, except for offset and same stator/charging system. The '09 and up 'Bergs are full DC systems stock.
