I have a home just outside Old Fort and I take the Dirt Road or Hwy 9 to Black Mountain. The 500cc works great with my 205 lbs and my grandson's 85. Stay off the inter-states at all cost.Ride safe, Bob.
...I think they make better bikes for climbing mountains.
The Indians also take the poor little fragile REs into the Himalayas, which by last reckoning a might bit hilly.
The original poster wanted to know if it was safe to ride home from the dealer on I-40, (70 mph speed limit), climb Old Fort Mountain (always semi's overheated climbing that hill, 7% grade for 5 miles) with his wife on back (400 lbs total) with a new, not broken in bike. I offered him my trailer.A broken in bike can handle the mountains. This was a recipe for disaster.
