There is no reason for you to fear this old Yamaha because it is as rare as Bigfoot or the Loch Ness Monster. There are very few of these, and at this point, they are pretty much all locked up in museums for safety. Kenny Roberts, one of the most talented road race and dirt track riders ever, raced it once and won the Indianapolis mile on it, but said never again. He was quoted as saying “they don’t pay me enough to ride that thing” and he was getting pretty well paid at the time. He has ridden exhibition laps on it in recent years, but even on the best tires currently available 125hp from a peaky 2-stroke 4-cylinder motor is just too much in the dirt.
