Only averaging about 4 K miles per year, so might as well spend a couple extra dollars. My brother is talking like getting a bike again, possibly a BMW, Suzuki or Triumph adventure bike.
I never took the Goldwing to Hudson Bay in Canada with my son. Just never came together, and he is 20 now. But my brother and I are talking about it.
Wonder if the Rocket can be fitted with Goodyear Wranglers?
