Since getting my '05 I've struggled with hip cramps, sometimes after only an hour, sometimes taking a little longer to occur. I have a 34" inseam and have fitted Suburban footpeg relocators which helped but the cramps still remained. So, time for a little creative thinking. I feel as though my hips are at the wrong angle (hard to explain) but I feel they need to rotate forward slightly and the K12 seat tends to make me sit in it rather like a bucket. So I duplicated the seat adjustment bar, adding 25mm more height than the standard highest setting and, presto, no cramps after 1 hour. I now need a longer test ride but it looks (feels) promising. Works for me, I just need to modify the seal latch bar now so it can be locked down. Not a difficult solution and possible to revert back to standard in 5 minutes if required. Give it a try if you have a need.
