I grew up with these in Europe. 5HP, limted to 40kph.

 

My best buddy won one of these in a radio contest back in the day. It wasn't very useful because of the convoluted driving laws here. It was basically a moped, but it did not conform to moped regulations - did not have pedals and was a little too fast.
As a result it had to be registered and insured just like a "real" motorcycle and you had to have a motorcycle license.

 

Thanks for the input. Guess I was too slow on the San Diego craigslist ad posting is expired. I'll keep looking

 

Those were funky little 50cc 2 smokes for the street. When I had a Honda SL100 I thought I wanted one of these until I rode a friends. They were pretty gutless but sounded cool with the ring-a-ding. Save up for an old RZ350 if you want a nice small 2 stroke.

If your hellbent on the MB5 here is one in SoCal for $500...http://inlandempire.craigslist.org/mcy/1707543339.html

 

While you're looking for the MB5, you might as well look for a CR80 motor.
I hear it makes for an entertaining combo........

 

Used to be a racing class down here for the MB. Ran 'em on the local go-cart tracks, much preferred over the Lambretta's and Vespa's.
