The statistic I heard was that in 1981, they sold more 490s than Honda sells all kinds of dirt-bikes of all sizes today. And then of course, they also had the 250 and 400 for sale at the same time. One thing to keep in mind, though, is that they never really had the big Monster Industrial mass-manufacturing plant where the bikes were stamped out and rolled off like Model-Ts. These things were hand-made, and that means overhead was gnarly. That's why, even though they were selling 'em as fast as they could make 'em in 1981, they still felt like they needed to go monoshock in 1982, to keep from falling! At the same time, Husqvarna was staying with their world-beating twin Ohlins setup, and although they had some of, if not the best suspension in the bidness, they lost big sales because they looked outdated. Combine Maico's catastrophic monoshock failure with Husky's stubborn refusal to re-invent the wheel, and Honda's truly ass-kicking CR480, and you've got a recipe for two of the big three "Yur-peen Iron" marques falling off the radar.
