I've spent 5 hours on my 14R, and am toying with the idea of doing a road trip to Las Vegas from the SF Bay Area. In my car it is an 8 hour haul. Wondering what's your stamina on the bike - in terms of hours. I was fine on my 5 hour ride, but glad to get off, but mostly due to dropping temperatures after dark getting into the low 40's, and I was wearing summer gear (It start out at 70 during the day, but dropped like a rock after dark).
I've done 6 hour hauls on other bikes just fine... seems to me as long as the weather is not cold or windy, should be good to go.
