Across the Country on a Honda C70 Super Cub - ADVrider
I love these stories where someone takes an old cheap motorbike on a long trip. This guy is 18 years old - riding an old Honda moped, that he fixed up himself, from California to New York with a budget of 600 dollars. Top speed 35 mph. Dangerous? Yes, but totally awesome. He's got some writing skills too.
This isn't his bike but this is what a Honda C70 Super Cub (also called a Passport) looks like.
It's got a 72 cubic centimeter engine (4.4 cubic inches), about 5 horsepower, and gets 115 mpg.
I've posted a link to this one before Sydney to London on a moped called Dot - ADVrider it's quite an epic moped adventure as well.
One of the nice things about being young is you don't know what you can't do. An older person creates lots of rules about what they can't do and would think of all the reasons why riding a moped for thousands of mile is impractical, foolish, unsafe - and miss out on a great adventure.
