What's the story with all the road bikers in Bellville last night?

[MildlyWild]

I drove north on Carl Cronje around 19:40 last night, and before and under the the N1 bridge crossing Carl Cronje there were about 50+ bikers parked at the side of the road and under the bridge, with traffic police all over and cars backed up.
Any idea what that was about?
