Try some of these simple modifications


1. Remove the front suspension rubber rebound stoppers. You will gain an 
   extra inch of front suspension travel.

2. Grind off  some of the steering stop tabs. The turning radius will be
   greatly improved.

3. Mount the seat on old automotive valve springs. The ride will be a lot
   smoother.

I have seen a Honda Odyssey with a rear suspension from an old 3-wheeler. It was a quite simple design and worked excellent. Older 3-wheelers are very cheap to buy, considering all you need is the rear end so it doesn't even have to run! The way it works is: The swing arm is mounted underneath a frame cross-member. It has 2 sprockets mounted on the fastened side and 1 sprocket on the end with the wheels. The 2 on the fastened (hinged) side are used to go from the stock axle (which another sprocket has been welded to)and then to go to the actual sprocket that drives the wheels. This allows the up and down movement of the swing arm. That was tricky part, the easy part is attaching the actual shock. It can be mounted anywhere, you may have to make a bracket to hold it but that isn't too hard. Depending on the size of tires on the 3-wheeler, you may have to chop the ends off the stock axle. If you decide to try this I can not be responsible for screwed up Odyssey's. So make sure you know what you are doing before you do it. Good Luck. I have drawn up a little crude drawing, I hope it helps!
