Our NSU Maxi was AMCA judged 98.75 points with a point deduction for a blemish on the seat trim and 1/4 point deduction for the wrong spark plug cap. It is a favorite of Blue Moon's owner John Landstrom and after 20 years in his collection it is now offered for the first time. This wonderful Maxi was displayed at the Keenland concours where it took a best in class award. It will be sold serviced and running perfect.
