It depends on what you are looking for. Almost everyone I know with a FJR finds the rear shock under sprung, and it wears out after about 15,000-20,000 miles. The front suspension usually needs work also, either springs, or internals. This can cost anywhere from about $1,500 up to over $3,000. The extra $1,000 the ES costs is a bargain compared to that. And it is still better because you can adjust it on the fly. You can also rebuild the ES shock for about $100.
There is a reason that the A model is being discounted so much. No one wants to buy them. If you are one of the riders that can't tell the difference between a bike with a suspension that works well and one that doesn't, then the ES is a waste of money. If however you like the idea of having a suspension setting that works on a twisty road, then can be changed with a couple button pushes to soak up expansion joints on the freeway, then the money for a ES is the greatest bargain of the century.
