Roland might have won a race or two, but I don't think he ever had a championship. Rich Oliver was around at the same time and was in a league of his own on the track. Everybody knew they were racing for second place in 250s when he gridded up. In his defense, I think Roland was banging most of the umbrella girls, so he still had a pretty productive racing career.
I'm not trying to tell the guy how to build a bike...but when you have over 200 horsepower you might want to think about using a front brake. I'm crazy like that.
