There are very limited options for the K1200LT/Hannigan conversion in this area. I ended up making my own pegs which work very well for the occasional leg repositioning. I've also found that the width of the K1200LT Tupperware spreads your legs quite wide just to rest them on the pegs. This position in itself becomes uncomfortable after a while! I have attached a link to the construction of this modification if you decide to go that route.......
