I have had an '81 MC490 and an '83 Husqvarna CR500. The Husky was a great fast, good handling, heaps of power, easy to ride bike. The Maico was a fast, good handling, heaps of power (a little less than the Husky), easy to ride bike. On the track I think the the Maico would get the nod because it revs a little qucker and feels a little lighter, but very close. In the pits, if you can get past the legend status of the Maico, it's 6 of one, half a dozen of the other, although I would probably vote for the Husky with the white, blue, yellow colors and the cool alloy tank. You could buy a Husky for about 50-75% of what you have to pay for a Maico as well. I've had a few Maico's and I still reckon a '77 AW400 is hard to go past for an all rounder. Maico clutches are a little harder to live with as well. I've also ridden '83 Honda CR480, nice bike, '84 CR500, too much power, not as good as the 480 in my opinion, '84 RM500, nice smooth torquey power and '84 KX500, once again nice and rideable. I've never ridden a Monty 414, but the 360 is a great bike. In the real world it all boils down to what color you like and how much cash you have to get what you like. Here's a similar question: Blonde, red or brunette?
Cheers,
