Impressive power curve, I would love to see that overlayed with a modern CRF450. I imagine the CR would make it look a little anemic!
They are a real mans bike them which is why I never raced one , I found a 250 was more than adequate for breaking my bones
Back in the 80's when all the top riders raced the Le Touqet beach race the works Hondas used to pull 125mph plus down the main straight.
