I have never tried a 50CC. I wanted to do one in November last year but didn't happen.
Living in Phoenix, AZ I would need, eventually, come back to Arizona and this leaves me with basically two options:
1. 50CC west-east and get back visiting NP's without interstates. This will require a lot of time.
2. 100CCC. This is faster but not having done a 50CC not sure if a 100CCC is the best option.
I used my 50CC to start my NPT SILVER ride. Getting the first 2 corners (Florida & California) & 13 states & 23 national parks going to & returning home from the ride. Also, got to ride Death Valley NP, which was one of my bucket list rides.
