I just saw this mini bike and the story behind it.
...and searched for a relative thread to share this SUPER RAd MaChiNe!
"POLARIS X60...made for only 3 years...bordering 1985"
Polaris X60 Mini Bike
"For several years I have been competing in the National Mini Bike Championship races in Deweese, Nebraska. Every year I would craft up new killer bikes but always returned frustrated. However each of those years I would watch who won and on what. In the modified class it was a fellow on a Polaris. It wasn’t faster than others but it always won or placed high. I deduced it was the suspension-none of the others had it. I didn’t realize until much later the super secret is the torque sensing belt and jack shaft drive. I promised myself if I ever found one I’d snatch it up. It happened. I found this one in Wisconsin for $225. The Polaris X60 mini was only made for 3 years, I think, in the years bordering 1985. I don’t know why they stopped making them-they were advanced for the time and in the vintage classes today it is supreme. I didn’t keep much of the original bike just the frame, the dual drive system, the sprocket and the tank. The original tank is plastic, Clark I think. I covered the plastic with fiberglass so it would take paint without bubbling off. Since the rear had real shock suspension I matched it with 33mm forks I had under the bench. I used a pit bike rear disc brake which is hand operated. It’s Chinese and wonderfully cheap. Exhaust and tail section were scratch built. The engine is a Briggs Animal. The first time I rode it I was blown away. With the big engine, snowmobile style belt drive and the jack shaft drive it’s a torque monster and just rips. You can feel it shifting up as it speeds well past 50 mph. Now I’m ready for the 2011 Nebraska race."
