Heya... that's probably the most common complaint amongst us more "vertically challenged" trumpy owners. I have seen a footpeg reloaction kit, but it was over a year back and I didn't take note of the manufacturer - perhaps someone else here remembers it, as it's not showing up on the old forums or google either.
The easy answer is footboards - I had the dealer put them on my bike pre-delivery and at 5'8 I can comfortably ride it all day long.
