Interesting! Some archive pictures from the old circuit there when they used to go along the prom in Portstewart.
I used to go every year between about 1984 to 1995. We always used to sit at the pits. There's nothing quite like a grid start on public roads. 2 waves of 36 bikes blasting off to the first corner at well over than 100mph. The top speed trap time this year was 204mph!

indeed!
Maybe you will find something else to interest here:

Hopefully they will repeat that next year
