Honda Passport C70. I wanted one of these for a long time, ever since reading a Peter Egan article about his road trip on one back in the day. I was enchanted with stories of it's indestructibility and ease of use, I thought it would be fun to run around town on..and maybe one day take a overnight trip with it just because.
Working on it was just painful though. I had to fix something simple, I forget what, but it involved removing the rear wheel, shocks, exhaust, etc. I thought it would be a relaxing project, but it was way more frustrating than my DRZ or Tiger. And because it was 70cc, insurance would have been just as much as my other motorcycles.
It was fun to ride around the neighborhood and through the yard, but next time I'll just get more modern moped if I feel the need.
