I hear you about the tires and traction. My friend had an '84 Honda CR500 (the last air-cooled model made), and I had an '82 Yamaha IT 465. In drag races in the dirt, we were usually pretty even despite the fact that he had considerably more hp & torque. He remedied the situation by swapping out the stock tire with a Cheng Shen they used to make which had a huge, wide center knob. About the closest thing to a sand paddle you could get and still have a knobby. He generally roosted me after he slapped that tire on. I wonder if they still make that tire. I know about the Maicos being deceptively quick, and very tractable as well. My brother-in-law had a 1985 Husqvarna CR500 2stroke. This was the MX model, not the cross country or enduro. It felt like nothing in the world could accelerate with it, and it was quick, but fast as well, having a 6 speed. His policeman buddy bought a 1981 Maico 490 in near perfect condition. Just riding the two and going by your seat-of-the-pants, you'd swear the Husky would run off and leave the Maico. Not so. The Maico always edged it out through the gears in roll-ons, and easily won standing start drag races. Well, that is, until the Maico topped out in 5th, then the Husky would come screaming by, having a 6th gear and much higher top speed. Maico seemed to work magic with the motors they built, that nobody else could duplicate. Enduro-like powerbands, with MX horsepower, but very broad and tractable as well. Having said that, the results between that Maico and Husky might have been very different on pavement, but they never tried. I'm pretty sure the Husky had more peak power, but didn't get as good traction.
