Quite a while ago I had a post including a photo showing one of the most spectacular Scandinavian racing motorcycles I have ever seen.
This was the Super X "Big Bertha" converted short frame special who once belonged to the famous Swedish racer Helmer Petterson.
Since my previous post on this blog regarding this bike (had to check when, and to my surprise it was almost two years ago, April of 2011) I have learned a lot and more pics of this very interesting bike have surfaced.
I will in this post sum up what I have learned so far regarding Helmer Petterson and his reputation as a motorcycle racer on X brand bikes.
I will start this post by re-posting the first pic I found on Helmets Super X, captured during an ice race in 1930 at Sæterviken bay near Uppsala.
