I hear a lot of talk about using memory foam in seats.The article I posted says it's not the best choice, any opinions? I am looking for something to improve the sundowner passenger seat to evenly disperse the weight and absorption of bumps.

There is a lot to consider when finding the right seat, bottom line is everyone will have a different opinion based on their own experiences - so just because something is good for one, doesn't mean it's good for you...
If you can find a good seat guy out your way that does custom seats, I would start with him and pick his brain...

 

The term "Memory Foam" just refers to the fact that the foam will return to it's original shape after being decompressed. Memory foam on motorcycle seats is exposed to the heat of the sun or the body temperature of the rider/passenger. As the memory foam warms it becomes useless due to the fact it completely compresses. In my opinion, stay away from "Memory Foam" products, they are just a marketing gimmick.

I would first check your suspension sag. Your rear shock tention may not be setup correctly for the weights of the rider and passenger. You and your passenger should weigh yourselfs while wearing your riding gear. Also take into account what's in your saddlebags if you have them. If that weight rises above 250 lbs then you most likely need to get shocks with "Heavy Duty" springs.

To measure the sag you will need a motorcycle jack, a friend, and the rider and passenger.

1. Jack up the motorcycle so the tension is released from the rear shocks. Find two points to measure between. The top and bottom shock bolts are a good place to measure from. Make note of the distance between the two measuring points.

2. Let the motorcycle off the jack and have the rider sit on the bike. Have your friend measure between the same two points and take note of the distance. The distance should be between 1/2 inch and 1 inch. I aim for 3/4 of an inch. Adjust your shock tension accordingly.

3. Repeat the steps with both the rider and passenger on the motorcycle. Remember to wear your riding gear.

Adjusting the shock is different depending on the shock. Some can be adjusted by hand while some need a spanner wrench. Check your owner's manual for the correct procedure and to get the specs on what weights the stock shocks can support.

You are going to find that the correct shock setup will help much more than a new seat. If you end up needing to upgrade the shocks it will be more expensive than a new seat, but in my opinion your ride will be more comfortable.

 

Very good advice!

 

It sounds to me as if your rear shocks aren't suitable for your application. If they were the bumps wouldn't be getting through or troubling you. Are you carrying a passenger you want to make more comfortable? If so consider upgrading your suspension, which will benefit you both. We have suggestions!

 

I modified my Sundowner and put gel inserts (from saddlemen) in the seating areas and covered them with 1/4" closed cell foam. My passenger was very happy with the mod but I couldn't tell much of a difference.

 

The best seat I have owned was a custom seat I had made for my Ironhorse. It had air chambers in the driver and passenger seats. But it was a $2000 seat. That being said, you might could look into this idea. Just at a glance, you may could take some foam out and add some of these and then lay a 1/4" foam sheet over before putting the seat back together. Just an idea.
