I'm sure your transmission will get a workout at those elevations.

Yesterday I rode my RX3 over the Teton Pass, a twisting steep road which connects Jackson, Wyoming to Victor, Idaho. The pass tops out at 8,431 feet, but it taxes the transmission because of the constant turns, which prevent you from either building up, or maintaining much speed.

Near the top I was running about 8,000 rpms in third gear, even with the 13T C/S sprocket. However, I didn't hold up traffic, and I was able to maintain the speed limit without shifting below third gear. I'm sure I could't have traveled that pass without obstructing traffic, if I still had the 14T C/S sprocket installed.
