The OEM seat on my '09 Heritage is OK. I can live with it, but would like to find something better. But I'm a big guy (6'4", 270) and I need a big seat. I just sent a C&C seat back. It was very nice, very well made, but it was too narrow for me. So here are my parameters:
Can't sit me closer than stock seat
Can't sit me higher than stock seat
Must be as wide as stock seat (or very close)
So C&C is out, Mustang is out (sits higher). Any other suggestions?
