My guru for suspension, Peter Verdone, says that the tires are the most important suspension component, but the ES only changes the spring preload and the spring(s) damping. Since damping's purpose is to complement the spring and needs to be adjusted whenever the spring rate changes, its hard to make an argument that damping is more important than the spring rate......at least to achieve an ideal suspension setup. Once the spring rate is selected and installed, its fixed and then you have to use damping and preload to get the best you can with what you have to work with. I think the ES spring rate is going to be far from ideal for loads over 300 pounds and the ES's inability to change rebound and compression damping independently is going limit the benefits from changing spring rates.Good questions! The problem with every OEM suspension is that one size is supposed to fit all and there isn't any shock spring that is going to adequately cover the 150-450 pound load range available on the FJR. Spring rates are the most important suspension component and I think the aftermarket suspension's option to select spring rates specificially for the rider(s) and riding style far outweighs the ES's ability to make minor damping adjustments on the fly. As stated, the OEM spring rates probably are designed for lighter riders so I expect they will get a better result from the ES than heavier or 2-up riders.So what about for a guy that's 250lbs? These bikes are setup for an 180lb guy, is the ES worth the money or should I save the coin and just do custom suspension? I could always set the dial to 2 up or 1 up with luggage to compensate for the extra weight from all my muscle mass. I don't ride 2 up so I don't need to worry about that. The advantage of the ES over custom suspension is the ability to change on the fly. Run it in comfy mode for the slab and bump it up to sport for the twisty's.
My experience with aftermarket suspensions is that once dialed in they work well with all road surfaces and riding conditions, the only time I have felt a need to change the damping is when there is a large temperature change.
I am going to disagree with you a bit there. I think spring rates are only one aspect of suspension, and not the most important. Though the farther from 'ideal', the harder it is to compensate. I also have enjoyed my aftermarket suspensions, though I have never been able to dial one in so that it works well in all situations. I still find trade-offs between comfort and sport. IOW, you can have one or the other, but not both. Much like for a car.
As for the trade-offs between comfort and sport, suspension's main objective is to keep the tires in contact with the road, and the better job it does at doing that, the smoother the ride and the better the ride quality. If you read Ducati's description of what its new electronic Skyhook system is trying to achieve, its actually describing what what every suspension system is attempting to accomplish. Very soft suspension may feel very comfortable on a short ride but rocking and rolling for several hours is much more fatiguing than riding on a suspension that resembles the Skyhook system. Nevertheless, suspension is always going to be a compromise for any rider due to changing loads, road conditions, and speed (especially speed) but that compromise is actually a compromise of spring rates and the compromise of a one spring size fits all for all conditions is going to be a bigger compromise than the ability to make small damping adjustments on the fly (although it would be pretty cool if you could change the 4 damping adjustments independently of each other rather than having to move all 4 in the same direction).
