You can get any seat the fits your range and remove the cover and shave the foam down about 2 inches or so. Anymore and the seat will be uncomfortable. You can also get "shorty" shocks. There are some for about 80-100 clams. That also drop about 1.5 - 2 inches.
Dont forget the front too. If you drop the back, you should drop the front slightly. You can raise the forks about 1 inch in the trees. Anything else though means different fork tubes.
The ride IS the adventure. The destination is just to get gas!
