Yeah I know, I'm supposed to hate pre '85 bikes but if the truth be known, I reckon that the 80s produced some of the most interesting and revolutionary bikes in our sports history. One of the more interesting bikes of that era is the ATK560. Developed by Horst Leitner, these gems were a decade ahead of everyone else in suspension and braking technology. Check out the linkless, single sided rear shock and you'll see where KTM got their ideas from. They had Whitepower USD forks, and heaps of other features not seen on other brands for another decade. A similar bike to the '84 560 ATK shown below is enroute to the Firko Collection as we speak. I may not be going to motocross race it, at nearly sixty I'm way past my useby date for wrangling a 55hp open classer but may put a guest on board it for the Nats and will look forward to myself punting it around the odd dirt track and Vinduro poker run.
