I very much prefer the original, (and wanted one for decades, maybe still do), it evolved over the years, I think Munch ended up making the entire engine unit, the originals were of course car type, NSU Prinz engines. Sammy Millers daughter has just bought one for the museum, a year or so ago, and it cost £180,000! 70's of course, I dont gell with the last of the line, that chain guard is so ugly??? strangely I detested the Shifty for decades, (Fiat 127 engine/ Laverda chassis) sort of in the same mould, but now, I would like one of those!
