MZ/MuZ Riders

looked for one of these since 1970 they were made in Athens Ohio about 50 miles from where i live

and it is a hoot top speed is 39 mph on my gps need to change that front sprocket to about 3 teeth larger
one wheel drive on right rear...
it needs to run with the trafffic on the fast roads across the bridges here in town
need to do at least 45 to not get ran over
it makes a smart car look big
