I am about to buy a ´73 350 CB. I have been tooling around on a ´67 150cc vespa sprint and have decided it´s time to move up. I am excited about my new little honda, and even though it´s small I want to do some longer trips on back roads. Any suggestions/precaustions I might want to take? The top speed is listed at 75. Whats a good cruising speed then?
