If you choose, you can also go the route I chose... I work for a company that manufactures our own 3 wheeled vehicle.. The company that builds our seats was so impressive that I had them build me a seat for my hayabusa... The took my spare stock seat (I was using a gel seat), shaved an inch of foam, replaced it with a better type of foam, added a pro pad and then did a full custom cover... It's hands down the best seat I've ridden with.. On your average weekend I'll ride 500-700 miles and I don't find myself "shifting in the seat" for comfort like I used to, and I no longer have the heat soak problem that gel seats are so well known for...
