Riding a slow bike fast is much more fun than riding a fast bike slow, and 50ccs is right around where most every riders started their two-wheeled lives. Nowadays, the Monkey Bike seems forgotten, the engines have only gotten bigger, and some of that simple joy has been lost. That might be reversing, though. Buyers are increasingly enchanted by minibike nostalgia, as evidenced by the meteoric rise in Honda Trail 70 values. The upcoming Bonhams’ Zoute auction in Belgium, kicking off October 11, has five JDM minibikes that we never got in the U.S. Is this the moment to add a tiny, but powerful splash personality to your vehicle fleet?
