As the others say, it depends on what you want to do with the bike. You can race any year Maico through the '83 model in AHRMA events and other regional vintage series. The early 70s Maicos are fun to ride but expensive to maintain (ask me how I know this!)and you will seldom find a good example that's ready to race for less than around $2,000. If it IS less than that, there's likely something wrong or in need of replacement. Parts are not a problem to find (Maico Only and NW Maico/CZ have about everything). The mid-70 Maicos are plentiful and there are some bargains out there becuz this is a relatively under-raced segment. At the top of the heap are the 490 Maicos from '81 thru '83. These bikes are still competitive against mod bikes and a helluva lot more fun to ride! I don't know why some people claim they have too much power, becuz it's great, ez-to-use power that lets you ride at your best. The famous quote about a 490 Maico is: "If you can't win on one of these, take 6 months off racing. And then quit." Yeah, I've got one of these too. A good race-ready 490 can be expensive, but there are also some bargains out there if you look hard enough.
