I had a chance to ride up through Yellowstone Park and over the Beartooth/Cook City highway to Roberts Idaho and then back over the Chief Joseph Highway on the way back. Later in the month I rode to Boise and then with my son, Mark, up to Highway 55 & 95 to Lewiston and down the Oregon side of Hells Canyon. EPIC! From Pocatello and back it was about 1300 miles over 4 days.
I rode about 50 miles the day and it did seem to be broke in better, but haven't ridden any long rides since.
On the DRZ400 I had a couple opportunities to ride 25-35 miles. I replaced the foam with a softer foam. (the foam pictured is the original foam) I added some padded bike shorts to the ride and between the two, fared significantly better.
Anybody else have any issue with uncomfortable seats?
