Get one
i visited the FJR club work shops (local to me) for other things and had a run on my bike with one put on. I was hooked after 20 minutes and flexible friend in credit card came out and job done. I had a 2K trip with same the following week and confirm it is good, and as my a**e moulds it, it gets better.
Not gel but well made and very firm

As tonto said, if you e mail the FJR club they will give you a price to ship across the pond, they will want your old seat back mind !!!
