The top one belogs to Jim McCabe-a Maico rider since 1956 from Indiana USA. He has been very helpful on the Yahoo Maico forum. The Machine is intended to get a speed record at Bonneville Salt Flats. Rick Sieman aka "Super Hunky" saw it and thought it was a waste of a 490 Maico...but now thinks it is cool.
I have not seen pics of the second one before, but it is likley McCabe's as well.
He has more than a few Maico hybrids etc.
