Can't seem to find it anywhere - is there a difference between the 2003 ST1300 and later models? Seems I recall reading somewhere that there was a height difference? I'm trying to figure out why I'm not as comfortable on the 03 as I was on the 04. I have the same riser and the same seat now, and still it doesn't feel right. For the most part, I'm only commuting about 15 miles or so, and by the end of the ride, my shoulders are staring to ache. Yes, it's been about 5 years since the 04, but I have the pics, and the riser looks the same (same manufacturer), and the seat is a Sargent on both. I was commuting about 40 miles one way on the 04 and didn't have issues, so I'm not sure what's up with the 03.
